Norbar® Torque Tools
History
In 1942 the ‘North Bar Tool Co.’ (as Norbar was then known) became the first company in Britain to
commercially manufacture a torque wrench. The initial demand was driven by the need for the
gasket-less cylinder head of the Rolls Royce Merlin engine to be accurately tightened. Bill Brodey and
his partner Ernest Thornitt obtained a license from Britain’s war-time Government to begin
manufacture of torque wrenches and Norbar was born.
Since then, Norbar has continued to invest in the very latest design, manufacturing and quality control
technology to achieve the highest level of innovation and precision in the field of torque control
equipment.
The company has grown from strength to strength and now has one of the largest and most modern
plants in the World devoted exclusively to the design, development and production of torque tightening
and measuring equipment.
Norbar is owned solely by the descendants of the founder, Bill Brodey, and they remain every bit as
passionate about providing customers with high quality, value for money products and services.
Global Service

What is Torque?
Torque is any force or system of forces that tends to cause rotation about an axis.
Measurement of Torque
Imagine someone tightening a bolt using a socket attached to a meter long bar. If they apply 10 kg of force (kgf)
perpendicular to the bar they will produce a torque of 10 kgf.m at the axis (the centre of the bolt).
However, under the S.I. system of measurement, force is expressed in Newtons (N) rather than kgf. The conversion
between kgf and N is x 9.807 so the person is applying 98.07 N.m of torque.
2m
1m
100 N
100 N
Torque = Force x Distance
Example 1: Distance = 1 m, Force = 100 N,Torque = 100 N.m.
Example 2: Distance = 2 m, Force = 100 N,Torque = 200 N.m.
Example 3: Distance = 1 ft, Force = 100 lbf,Torque = 100 lbf.ft (or 100 ft.lb)
The Importance of Torque Control
Although many methods exist to join two or more parts together, the ease of assembly and disassembly provided by
threaded fasteners make them the ideal choice for many applications.
The object of a threaded fastener is to clamp parts together with a tension greater than the external forces tending to
separate them. The bolt then remains under constant stress and is immune from fatigue. However, if the initial tension is
too low, varying loads act on the bolt and it will quickly fail. If the initial tension is too high, the tightening process may
cause bolt failure. Reliability therefore depends upon correct initial tension. The most practical way of ensuring this is by
specifying and controlling the tightening torque.
Bolt Tension
Torque
When an assembly is clamped by tightening a nut and
bolt, the induced tension causes the bolt to stretch.
An equal force acts to compress the parts which are
thus clamped.
The proof load of a bolt, normally established by test,
is the load which just starts to induce permanent set
– also known as the yield point. Typically bolts are
tightened to between 75% and 90% of yield.

Introduction
Friction in the Bolted Joint
When a threaded fastener is tightened, the induced tension results in friction under the
head of the bolt and in the threads. It is generally accepted that as much as 50% of the
applied torque is expended in overcoming friction between the bolt head and the abutting
surface and another 30% to 40% is lost to friction in the threads. As little as 10% of the
applied torque results in useful work to tension the bolt.
Friction under the bolt head
Friction in the threads
Useful work to tension bolt
Given that up to 90% of the applied torque will be lost to friction, it follows that any
changes in the coefficient of friction resulting from differences in surface finish, surface
condition and lubrication can have a dramatic effect on the torque versus tension
relationship. Some general points can be made:
•
•
•
•
Most torque tightened joints do not use washers because their use can result in relative
motion between the nut and washer or the washer and joint surface
during tightening.This has the effect of changing the friction radius and hence
affects the torque-tension relationship. Where a larger bearing face is required
then flange nuts or bolts can be used. If washers are to be used, hard washers with a
good fit to the shank of the bolt give lower and more consistent friction and are generally
to be preferred.
Degreasing fasteners of the film of oil usually present on them as supplied will decrease
the tension for a given torque and may result in shear of the fastener before the desired
tension is achieved.
Super lubricants formulated from graphite, molybdenum disulphide and waxes result in
minimal friction. Unless allowance is made in the specified tightening torque, the induced
tension may be excessive causing the bolt to yield and fail. However, used in a controlled
manner, these lubricants serve a useful purpose in reducing the torque to produce the
desired tension meaning that a lower capacity tightening tool
can be used.
For reasons of appearance or corrosion resistance, fasteners

As a rough guide, the calculated tightening torque should be

Tightening to Yield
Bolts tightened to yield provide consistently higher preloads from smaller diameter bolts.The reduced fastener
stiffness reduces the fatigue loading to which the bolt is subjected under repeated external load reversals,
e.g. cylinder heads and connecting rods.
In theory, a bolt tightened to its yield point will provide the strongest and most fatigue-resistant joint possible,
within the physical limitations of the bolt material and manufacturing process.
Down side of this method is the cost of the sophisticated equipment necessary to determine when the bolt goes
into yield.
Torque Tension Calculator
For further information and guidance on
establishing the correct tightening torque for a
fastener, see Norbar’s web site, www.norbar.com.
When Torque Doesn’t Equal Tight
As we have established, it is the tension in a fastener rather than the torque that is the critical factor. Torque is an
indirect means of establishing tension but, in a correctly engineered joint and with a controlled tightening process, it is a
satisfactory method under the majority of circumstances.
However, in joints that are highly critical due to safety or the cost and implications of machine down-time, a more
direct means of establishing tension is needed. Various methods exist including several types of load indicating bolt or
washer. However, one of the most versatile methods is to measure the extension of the bolt due to the tightening
process using ultrasound and this is exactly what Norbar’s USM-3 does. For full details of this instrument see Norbar’s
web site: www.norbar.com.

Recommended Maximum Torque Values
The information supplied here is intended to be an acceptable guide for normal conditions. For critical applications, further information
and research will be necessary.The following basic assumptions have been made:
a.
b.
c.
d.
Bolts are new, standard finish, uncoated and not lubricated (other than the normal protective oil film).
The load will be 90% of the bolt yield strength.
The coefficient of friction is 0.14.
The final tightening sequence is achieved smoothly and slowly.
If lubrication is to be applied to the nut/bolt, multiply the recommended torque by the appropriate factor shown in the table on page 7.
Alternatively, use the Torque/Tension Calculator on the Norbar website which enables fastener and friction conditions to be modified
with ease.

Torque Wrenches
TruTorque™ Wrench
Models 20 N.m and 50 N.m (180 lbf.in and 35 lbf.ft)
Durability has been a primary development goal – both in terms of the lifetime of components and
longevity of calibration accuracy. Cycle testing of wrenches at full torque was a key element of the
development process and, in total, several million tightening cycles were accumulated. The result is a
product that you can use with complete confidence that you have the best tool for the job.
• Accuracy: +/-3% of reading exceeds all international standards for torque wrenches. Each wrench
is supplied with a traceable calibration certificate.
•
Micrometer Scale for simple and error free setting. (On dual scale wrenches, the micrometer
increment applies to the N.m scale.)
•
Quick and Light Adjustment: adjustment over the entire scale can quickly be achieved and with
minimal effort in approximately ten complete turns (exact number varies by model).
•
Adjustment Lock: all models feature a lock to prevent accidental adjustment of the set torque.
•
Versatile Ratchets: the tough ratchets are reversible and have a narrow engagement angle of 5º to
allow easy positioning of the tool in the tight confines of today’s vehicles and machines.
•
Comfortable, Durable Handle: the handle is constructed using two materials: a base material for
strength overlaid with a soft feel grip for comfort and slip resistance. The handle material and
lens resist chemicals in common usage in the automotive, aviation and industrial environments.
Norbar Non-Magnetic torque wrenches are
designed primarily for the medical MRI scanner
market. However, they will prove invaluable where
ever a torque wrench has to be used in the
presence of a strong magnetic field.There are
currently two models: 1 - 20 N.m, Part Number
13292 and 8 - 50 N.m, Part No. 13293.

Professional Torque Wrench
The ‘Professional’ is Norbar’s core torque wrench range containing the most
popular models and the most model variants to suit almost every application.
More than 60 years of torque wrench manufacture has shaped this
range and no aspect of design, manufacture or materials is taken
to chance. Every new product and design change is rigorously
tested before introduction, a process that makes these
wrenches amongst the most durable and accurate
on the market.
Torque Mechanism
Adjustment Lock
A robust lock prevents
accidental adjustment
of the wrench during
use. Fingertip light
adjustment comes
from the best design
and materials.
Torque Scale
Ratchets
Unique ‘harmonic drive’ scale
mechanism allows a long scale
length and therefore accurate
and error free setting.
The Professional
torque wrench is
available with a choice
of ratchets and as a
‘Torque Handle’ for
interchangeable fittings.
Norbar’s accurate
mechanism has been
developed and
enhanced over a 40
year period and several
million examples have
been produced. Less
parts to maintain than
‘pivot block’
mechanisms. Simple
calibration adjustments
without disassembly.

Torque Wrenches
Professional Torque Wrench
‘Industrial’ Ratchet Models
These wrenches offer the same outstanding features as those on the previous page but
with a wider model range – up to 400 N.m – and a different ratchet concept.
The push-through ratchets on these models are robustly engineered for strength
and durability. The strength and high wear resistance comes from the design of
the tooth pattern while a principle of offset ratchet pawls gives a narrow
engagement angle of 5º on wrenches up to and including Model 200
and 6º on Models 300 to 400.
The push through square drive is not only a robust design
but allows the wrench to be used for torque control
in both the clockwise and anti clockwise
directions. Please note that the 3/4” square
drive of the Model 400 has to be
removed and re-inserted on the
other side of the ratchet
head rather than pushed
through.

Torque Handles
Norbar Torque Handles are based on the
‘Professional’ wrench range and share the same
high precision engineering.
Two end fitting styles are catered for: 16mm
diameter spigot type and the 9 x 12mm and
14 x 18mm rectangular type.
For many applications a spanner end fitting rather
than a socket is the best or, often, the only
solution.Typically this will be because the joint
is a pipe union (such as a brake pipe).

Torque Wrenches
Electrode Wrenches
The correct tightening of carbon/graphite electrodes is known to increase the energy
efficiency of electric arc furnaces and prevents electrode sections from being lost in
the furnace.
Norbar Electrode Wrenches are based on two well proven torque wrench designs:
electrodes up to 8 inches use the ‘Professional’ type, 9 inches and upwards are based
on the ‘Industrial’ wrench.
•
•
•
•
Positive torque control increases energy efficiency.
Self-clamping action speeds the tightening operation.
Unmistakable signal when the set torque is reached.
A wide range of electrode sizes, 8 to 24 inches, can be tightened.

Handtorque™ Multipliers
What is a Torque Multiplier?
A torque multiplier is a device that increases the torque that can be applied by an operator. Because the power output
can not exceed the power input, the number of output revolutions will be lower than the number of input revolutions
(Torque x rpm = Power).
How Handtorque Torque Multipliers Work
Handtorque multipliers incorporate an ‘epicyclic’ or ‘planetary’ gear train having one or more stages. Each stage of
gearing increases the torque applied by a factor of 5, allowing Norbar to offer multipliers typically in ratios of 5:1, 25:1
and 125:1.
In the planetary gear system, torque is applied to the input gear or ‘sun’ gear.Three or four planet gears whose teeth
are engaged with the sun gear therefore rotate.The outside casing of the multiplier, or ‘annulus’ is also engaged with
the planet gear teeth, and would normally rotate in the opposite direction to the sun gear. A reaction arm prevents
the annulus from rotating, and this causes the planet gears to orbit around the sun.The planet gears are held in a
‘planetary’ carrier which also holds the output square drive.Therefore as the planet gears orbit around the sun gear,
the carrier and so the square drive turns.
Without the reaction arm to keep the annulus stationary, the output square will not apply torque.
Why use a Handtorque Torque Multiplier?
• Safety – use of long levers can be dangerous.Torque multipliers mean a reduction
in the lever length or operator effort by a factor of 5, 25 or 125.
• Space limitation – the use of a long lever may be impossible due to the available space.
• Accuracy – torque will be applied most accurately when it is applied smoothly and slowly.
Torque multipliers enable this by removing much of the physical effort from the
tightening task.

Torque Multipliers
Advantages of the Norbar Handtorque System
Norbar gearboxes are built to an extremely high standard of precision. All gears
rotate on needle roller bearings about hardened and ground journal pins. As a result,
Norbar Handtorques can be relied upon to have a torque multiplication accuracy of
±4%, throughout the operating range, taking the uncertainty out of high torque
tightening.
No gearbox is 100% efficient and so the velocity ratio (the number of turns that the
input has to make to achieve one revolution of the output) is not the same as the
torque multiplication ratio. Norbar multipliers are engineered such that each gear
stage has a velocity ratio of typically 5.45:1 which results in a true torque
multiplication factor of 5:1.
Torque output calculations are therefore a matter of simple arithmetic with little risk
of incorrect bolt loading due to conversion errors. Other manufacturer’s multipliers
often require graphs or formulae to calculate the input torque to achieve a
particular output.
The Norbar Handtorque is the most comprehensive multiplier range available.
Standard products are available up to 47,500 N.m (35,000 lbf.ft) and ‘specials’ to
100,000 N.m (73,000 lbf.ft). A range of ‘nose extensions’ for reaching difficult to
access bolts and a full range of torque transducers for highly accurate torque
monitoring are available.
Summary of Norbar torque multiplier advantages:
• The ratio stated is the true torque multiplication factor.
• No correction charts are needed to determine torque output.
• Strong, safe Anti Wind-Up Ratchet available on most models for safe and
comfortable operation.
• A wide range of alternative reaction styles are available making the Handtorque
adaptable to many applications.
• Electronic torque transducers are available on most models for precise torque
control.

Norbar Anti Wind-Up Ratchet
With any high ratio gearbox (25:1 or more) a certain amount of wind-up (backlash) has to be taken up before
any useful tightening work is applied to the nut.
Each time the input device is released, the wind-up will rotate it back against the direction of operation.
The Anti Wind-Up Ratchet retains all of the wind-up forces as they are created with the following benefits:
1. The torque input device can not fly backwards against the direction of operation if it
is suddenly released.
2. Without an Anti Wind-Up Ratchet, it will often be necessary to continue to make
360º sweeps with the torque input device otherwise the multiplier will ‘unwind’.
However, obstructions will often make this impossible.
3. With an Anti Wind-Up Ratchet fitted, the multiplier becomes locked onto the nut
because the reaction plate is held hard against the reaction point.This means that
even used upside down, the multiplier will support it’s own weight.
Norbar’s Anti Wind-Up Ratchet
Multipier
behaves like a
very stiff ‘spring’
Multiplier will
achieve maximum
torque only after
the ‘spring’ has
been taken up
In this application
the Multiplier is
used upside down
and is able to
support its own
weight because the
reaction plate is
held hard against
the reaction point
In this application, if it
takes more than 180° to
take up the wind-up at
the required torque, this
tightening operation will
be impossible without
an ‘Anti Wind-Up
Ratchet’

Safety Note:
Additional support is recommended as failure in the bolt, socket
or multiplier will release the wind-up forces and cause the
multiplier to drop.

Pneutorque® Pneumatic Multipliers
What is a Pneutorque Pneumatic Wrench?
The Pneutorque consists of a robust air motor driving a Norbar multiplier with three or more
stages of epicyclic gearing.
Torque control is achieved by adjustment of the air pressure. An air pressure versus torque graph
and a calibration certificate is supplied with each tool and allows specific torque values to be set. For
more critical applications, Pneutorques can be fitted with a torque transducer and the precise torque
output displayed.The tool can then be shut off at the desired torque either manually or
automatically using suitable control circuitry.
Air pressure graph supplied with each tool.
The Lubro Control Unit, 16074, is Norbar’s filter / regulator / lubricator. It is
supplied with 3m of high quality steel braided air hose and a 100mm pressure
gauge for accurate setting.
Why use Pneutorque Pneumatic Wrenches?
Hand operated torque multipliers are ideal for low volume or intermittent use or when
there is no power source available. However, for production lines or whenever a large
number of bolts is involved, a powered multiplier will save a considerable amount of time.
Pneutorque operation is quiet – less than 85dB(A) with absolutely no impacting.These
two factors make Pneutorques comfortable for the operator to use, reducing fatigue
and consequently increasing safety.
Pneutorques provide accurate torque control – on a given joint they will stall repeatably
to within ±5%. Using electronic shut off, this repeatability can be improved to ±2%.
Summary of Pneutorque Advantages
• Sound pressure level does not exceed 85dB(A) when tested in accordance with
ISO3744:1994.
• No impacting means less damage to the tool, socket and bolted assembly.
• Less operator fatigue, results in increased safety.
• Powerful – models available up to 300,000 N.m (220,000 lbf.ft).
• Repeatability of ±5% for accurate torque control.
• A wide range of attachments and accessories make Pneutorques adaptable to
many applications.

Pneutorque® PTM-52 Series
Internal Control and
External Control Models
The integration of electronic torque
measurement and control into the
PTM-52 Series is achieved with
the minimum impact on overall
tool size and weight. The actual
applied torque is accurately
measured at the output of the tool
meaning that a repeatability of +/-2%
can be guaranteed.
Shut-Off, Internal Control – these tools include a torque
transducer, easy to read LED display, control panel and a solenoid valve
to shut off the air supply once the desired torque has been reached.
The tolerance band within which the bolt must be tightened can be set
on the tool handle control panel. When the tool is operated, the actual
applied torque is displayed along with one of three coloured LEDs to
indicate a low, within tolerance or high result. The tool can be operated
in either N.m or lbf.ft.
Shut-Off, External Control – this version of the
PTM-52 incorporates a transducer, solenoid valve and three coloured
LEDs for the indication of low, within tolerance or high results.
However, all control functions and torque display are housed in an
external controller unit (purchased separately). External controllers can
give a much greater range of functionality than is possible on the
‘Internal Control’ version of the tool.

Pneutorque® Remote Control
72mm Series
Remote control versions have no direction/shut-off control on the tool but rely on
external pneumatic circuitry to provide this function.This opens up numerous
application possibilities for the Pneutorque ranging from simple stall shut-off in a
hazardous working environment to sophisticated, multi-spindle torque and angle
shut-off systems.
• Stall control gives repeatability of ±5% on a given joint.
• Torque transducers and angle encoders available for all models.These form the basis of
sophisticated control systems giving repeatability of up to ±2%. See page 83.
• Automatic Two Speed gearbox reduces run-down times.
• Each gearbox supplied with a standard reaction device or, on request, one specifically
designed to suit the application.

Geared Offsets
Originally designed to tighten plate heat exchangers where nuts have to rundown studs
of up to 1 metre.
Offsets are invaluable in situations where access is limited due to headroom or tool
diameter.
The Geared Offset has been developed to enable the tightening of fasteners in
environments where access restrictions prevent the use of a standard multiplier or
where excessive stud lengths prevent the tightening of a nut with standard sockets.
Each geared offset is manufactured to customers specifications and is therefore tailormade to their application. For this reason it is essential that we obtain as much
information as possible.

Torque Reaction
Principles of Torque Reaction
Newton’s law dictates that for every applied force there is an equal and
opposite reactive force. For applications requiring relatively low torques that
can be applied with a torque wrench this does not present a problem as the
reactive force is absorbed by the operator. However, if the desired torque
necessitates the use of a multiplier, the resultant reactive force can only be
absorbed using an appropriate reaction device.
Optional on PTM-52 and PTM-72,
Standard on PT72mm Series
For this reason all Norbar multipliers are supplied with a reaction plate or
reaction foot fitted as standard.
All of the standard reaction plates and feet illustrated have been designed to
enable the multiplier’s use in a variety of environments but, due to an infinite
number of bolting arrangements, it is impossible to have one reaction device
that will satisfy every customer’s requirement.

Optional Reaction Plate, 72mm
Series
0.5 m
In the above example, 2500 N.m torque output will result
in a reactive force of 5000 N at a point 0.5m from the
axis of rotation or 2500 N at 1m (see page 63).
What to do if the standard reaction device is not suitable
Optional Double Ended Reaction
Plate, 72mm Series
For those applications that do not permit the use of a standard reaction plate the
customer has three options.
• Norbar or an authorised Norbar distributor will design and manufacture
a special purpose reaction plate to the customer’s requirements.
• The customer can modify the standard reaction plate to suit his requirements.
• The customer can fabricate his own reaction device after liaison with Norbar’s
technical department or a Norbar distributor.
Typical Reaction with sliding ‘slave
square’, PT/HT1 to PT/HT5
Customers wishing to either modify the original reaction plate or fabricate their
own device should read the information on page 63 to avoid common torque
reaction problems.

Torque Reaction
Avoiding Torque Reaction Problems
It has already been mentioned that the reaction force is equal to the force being applied.
However, the magnitude of the reaction force is dependent upon the perpendicular distance
between the point of reaction and the centre line of the multiplier, ie. the greater the
distance the lower the force.
For this reason the point of reaction should be kept as far away from the centre line of the
gearbox as is practical.
Customers using or modifying reaction plates for Standard Series multipliers up to a
capacity of 3400 N.m should note that if the reaction is taken on the radiused part, the
reaction force is perpendicular to the tangent of the curve. Consequently, the further
around the radius the reaction is taken, the smaller the perpendicular distance and
therefore the greater the force.
Signs of poor reaction are evident on this
damaged foot. Reaction was taken at the
wrong point on the foot and burring
indicates that the foot was slipping off the
reaction point.
Although a longer reaction plate may mean lower forces, the bending moment close to the
multiplier will increase.
Customers extending the length of Norbar’s standard reaction plates should be aware that
an increase in overall length will result in a larger induced bending stress and should not
assume that because the reaction plate is strong enough at one length it will remain so
when extended.
Excessive side loading, resulting from poor reaction, increases frictional forces inside the
multiplier.This can lead to lower multiplication ratios (outside ±4%).
Points to remember
• Take the reaction as far away from the multiplier as
practical.
• Ensure that the reaction point remains square to the
multiplier wherever possible as this will minimise any
additional stress in the output square, which could
result in premature failure. If the multiplier tilts under
load, the reaction may not be square.
• For applications that do not allow the reaction to be
taken securely it is advisable to use a double
ended or balanced reaction plate.
Green shading indicates ideal area for torque reaction to
achieve multiplication factor better than ±4%

Reaction Force
When using Multipliers and Pneutorques the reaction point must be capable of withstanding reaction force.Therefore, great care must
be exercised where reaction is taken when applying high torques to studs and bolts.
By using the following formula you can calculate the force at the point of reaction.The greater the distance the lower the force.
Formula to calculate Area of Stud = π x D2

Formula to calculate Shear Force: Shear Force = Reaction Force

Measurement and Calibration - Glossar of Terms
The following information may help in selecting the appropriate measuring device for your needs.
Accuracy
The precision of the instrument which can be reported in three ways.
1. By quoting the guaranteed tolerance as a percentage of the reading or indicated value, (eg. 0.5% of Reading ).
2. By quoting the guaranteed tolerance as a percentage of the full scale value of the instrument, (eg. 0.1% FS or 0.1% FSD).
3. By quoting a ‘class’ of device in accordance with BS7882:2008 Method for calibration and
classification of torque measuring devices . (See page 90).
Modes of peration
First Peak of Torque - when a click type torque wrench signals that the set torque
has been achieved, the applied torque will momentarily drop before climbing again. Generally
the fastener stops rotating at point 1, and from a standstill, the breakaway torque to achieve
further rotation of the fastener will be higher than point 3b. Only if the operator is very
insensitive to the break point will the final tightening effort be incorrect.
First Peak of Torque mode will detect the break point of the torque wrench, not the
highest torque applied.
Peak Torque - this mode of operation will record the highest torque applied. In the
1 = Torque wrench activates
2 = ‘Click’ heard
3a = Wrench released quickly
3b = Wrench released slowly
case of a click type torque wrench this may be higher than the actual break point if the
wrench continues to be loaded beyond the break.
Consequently, Peak Torque is more useful for calibrating devices without a break signal such as dial or electronic wrenches.
Track - this mode has no memory at all.When the load is removed the display will return to zero.
Track is used for calibrating the device itself or for monitoring a fluctuating torque.
Resolution
The smallest measurement interval that can be determined on the indicating device.
This applies to analogue and digital devices.
Number of igits
Digital displays are described as having a certain number of ‘digits’ or ‘active digits’.
Half digits can be used to increase the resolution of a device without the expense of going to an additional full active digit.
Eg 1. 1000 N.m displayed on a 4 digit system would read 1000 (resolution = 1 N.m).
Eg 2. 1000 N.m displayed on a 41 2 digit system would read 1000.0 (resolution = 0.1 N.m).
Active digits change as the torque changes. Non active digits only assist in showing the magnitude of the torque.
For example, 10,000 N.m requires 5 digits to display it’s magnitude.
Eg 3. With 4 active digits (and 1 passive digit), 10,000 N.m would change in steps of 10 N.m.
Eg 4. With 41 2 or 5 active digits, 10,000 N.m would change in steps of 1 N.m.
Signal Processing
Electronic Circuitry falls broadly into two types, analogue and digital, with most electronic measurement systems
comprising a mixture of the two.There are also whole analogue electronic systems, but these are rare in torque
measurement. Most systems start with an analogue signal.The point at which the signal is converted defines the type.
Analogue systems – one in which the signal is processed before being converted to digital.
Digital systems – the original analogue signal is converted to digital before processing.

Simple, Cost Effective Torque Testing
The importance of keeping your torque tools in peak calibration condition is well
established. Many businesses achieve this by using a third party calibration service.
However, how much more convenient would it be to perform calibration checks inhouse Tools could be checked more frequently, immediately if a problem is suspected,
and tools would not need to leave site unnecessarily.
The main reasons that more companies do not perform calibration checks on their own
tools are the cost of testers and fears over the complexity of the testing equipment.
Norbar’s ‘TruCheck’ torque screwdriver testers aim to sweep aside these concerns.
They are very cost effective being significantly cheaper than most similar products on
the market and the basic version of the TruCheck particularly is very simple to use.

One of the concerns in putting a torque tester into an environment where people
are not calibration specialists is that incorrect selections will be made with the
potential for incorrect tool setting and consequently tool failure. Norbar’s solution
is to remove all choices from the operator. The TruCheck is for click type torque
wrenches and comes with a single measurement unit (N.m or lbf.ft).There is only
one button on the device and that is to zero the display. Operation is simplicity

Torque Screwdri er Tester TST - Series 2
The TST combines simplicity with up to date technology to provide a high quality
instrument for the testing and calibration of low capacity torque tools.
Featuring an internal transducer complete with Joint Simulation Rundown Assembly,
the TST is available in 3 torque ranges, 0.04 to 2 N.m, 0.5 to 10 N.m and 1.25 to 25
N.m. Class 1 system accuracy over its Primary range (±0.5% of reading from 20%
to 100% of full scale).
What makes the TST genuinely versatile is the interface for an external transducer.
This interface, accessed by a 2 way switch in the TST, allows the connection of any
transducer from Norbar’s SMART range and most mV/V calibrated transducers
from Norbar or other manufacturers.
Norbar is UKAS accredited for the calibration of electrical torque indicator
displays and the TST is supplied with a calibration certificate.This ensures
that each element of the system is fully traceable and interchangeable.
The TST is also supplied with a UKAS torque calibration certificate
for the complete system i.e. display and internal transducer.

Torque Tool Tester TTT - Series 3
The TTT shares all of the extensive features of the TST except that it has no internal
transducer. Instead, the TTT offers not one but three external transducer interfaces allowing
any three transducers to be simultaneously connected. Selection between the transducers is
made by a rotary switch at the back of the instrument case.
Any transducer from Norbar’s SMART range and most mV/V calibrated transducers from
Norbar or other manufacturers can be connected to the TTT. The SMART feature means
that once a transducer has been connected, the instrument will automatically recognise
calibration details such as mV/V output, serial number and capacity.
Norbar is UKAS accredited for the calibration of electrical torque indicator
displays and the TTT is supplied with a calibration certificate.This ensures
that each element of the system is fully traceable and interchangeable.

Static Torque Transducer
The accuracy and quality of the Norbar Static Torque Transducers has made them the first choice of
many calibration laboratories throughout the world.
• Up to 6800 N.m (5000 lbf.ft) classified to BS7882:2008, typically Class 1 or better for the primary
classification range (±0.5% of reading from 20% to 100% of full scale).
• From 6800 N.m (5000 lbf.ft) up to 108,500 N.m (80,000 lbf.ft) classified to BS7882:2008, Class 1 to
Class 5 for the classification range (±0.5% to /-2.5% of reading) dependant on the type of transducer.
• Robust, heat treated, alloy steel torsion shaft design.
• Designed to ignore non torsional forces.
• Operates in clockwise and anti-clockwise directions.
• Calibration up to 108,500 N.m (lbf.ft) with a UKAS accredited calibration certificate.
• Calibrated in clockwise direction as standard. Anti-clockwise calibration provided on request.
• ‘SMART’ transducers have built in memory circuit which contains essential information about the
transducer.This information can be read by Norbar’s TST and TTT instruments meaning that when the
transducer is connected, it is immediately recognised and ready for use. When ordering for a TST or TTT,
use part no. suffix ‘.LOG’ (eg. 50659.LOG) if you require a torque units calibration certificate.
• ‘SMART’ transducers can also be used with many instruments not of Norbar manufacture. However,
these will operate as normal ratio calibrated (mV/V) transducers – the ‘SMART’ data will not be read.
For non Norbar instruments or for when a mV/V certificate is required, use part code suffix ‘.IND’.

Measurement and Calibration
Torque Wrench Loader
IS 1500 and 2700
These loaders allow torque wrenches to be calibrated or tested in accordance with ISO
6789:2003, BS EN 26789:2003 and American military standard GGG-W-686.Their
function is to take full advantage of the accuracy of Norbar’s torque measuring system
by reducing operator induced variations in the calibration process.
• The high ratio, 1200:1 (ISO 2700, 1250:1) gearbox allows high torques to be applied,
whilst ensuring that the operator does not exceed the rate of increase of torque
specified in the standards.
• The design allows for easy interchange of transducers using the Norbar Static Transducer
system.
• The ISO 1500 90 facility allows performance of torque wrenches to be checked in two
planes. Many wrenches give different torque values according to their orientation in use.
• Floating reaction point minimises side loads on wrench.
• ISO 2700 reaction extension bar allows wrenches up to 2200mm to be tested.This can
be removed to save space. Wrenches up to 1100mm can be tested when the extension
bar is not fitted
• Optional Small Reaction Plate (part no. 20588) allows torque wrenches down to
125 mm in length (centre of square to centre of handle) to be tested.
• Motorised version with speed control is available for the ISO 1500. This can be
purchased as a kit to motorise an existing ISO or as a complete ISO 1500 Motorised
Torque Wrench Loader.

Calibration
eams and Weights Principals of Operation
Norbar’s Test Beams are designed for the static calibration of Torque Transducers.They
are ideally suited to Norbar’s transducers, but can be employed on other
manufacturer’s equipment.
Torque is generated by the application of a known force at a known radius from the
centre of rotation of the torque transducer.
The Beams are designed with square drives machined to the top limit of ISO 2725.This
minimises any play between the beam and the transducer. However, a combination of
square drive tolerances, misalignment of fittings and elastic rotation of the transducer
shaft inevitably cause the beam to rotate from the horizontal under load.
Norbar’s Radius Ended Beams are designed with a +/-8 degree usable arc within which
the calibration accuracy is unaffected.
Additionally the beams are designed to apply load on a vertical plane which cuts
through the square drive inside the transducer.This minimises bending moments on the transducer and, for safe operation,
ensures that the beam will not fall out of the transducer.

ravitational Effects
It is very important that the gravitational value for the Laboratory is established.The effect of not doing this could
be a variation in the force produced by the weight of perhaps 0.5% of reading.
It is therefore strongly recommended that you establish the local value of gravity (g) for your Laboratory and use
weights that have been calibrated at that gravitational constant.
Norbar will supply weights calibrated to gravitational constants specified by the customer. However, if the customer
does not specify a value for ‘g’ they will have been calibrated at an estimated gravitational constant for the
customers’ location.
Buoyancy Effects
The Norbar system uses calibrated weights to generate a downwards force.
This means that Archimedes principle applies, ie. air pressure under the weights causes an upwards force.This
reduces the effective force generated by the weights and therefore the mass must be increased to allow for this.
Under standard conditions (ie. Air density 1.2 kg/m3 and 20 degrees centigrade and working in conventional mass
terms) the increase required is by a factor of 0.015%.
Weights purchased from Norbar will already have this factor taken into account.
Weights that are calibrated to standard procedures do not have this factor taken into account because the air
buoyancy affects both sides of the mass balance and can be ignored. It is important that weights used for torque
transducer calibration are adjusted for air buoyancy.
It should also be noted that the double ended beam design employed by Norbar means that each half of the beam is
balanced with regard to buoyancy of the beam.This is a significant advantage over
single-arm counterbalanced systems.

Calibration Certificates
As a UKAS accredited calibration Laboratory No. 0256, Norbar is required to calibrate torque
measuring devices that are within the Laboratory’s scope, in accordance with BS 7882:2008. See the
‘UKAS Schedule of Accreditation’ on the ‘Calibration Services’ page of our website,
www.norbar.com.
Norbar can provide a comprehensive range of calibrations including increasing and decreasing
torques clockwise and counter-clockwise in either SI or English torque units, or in mV/V or Volts.
The sections below summarise the main features of BS 7882:2008, but purchase and careful study of
the standard is advised for those who wish more detailed information.
Procedure
• The device” is defined as all parts of a system, e.g. Display,Transducer Cable, and Transducer.
Transducer cables will therefore be serial numbered if they are separate items.
• The output of the device is defined as deflection”.
• It is preferable to calibrate all parts of a system together. If a transducer is sent for calibration without
its normal display unit, an equivalent calibrated display held in the laboratory will be used.The normal
display must also be in a calibrated state or the certification for the transducer is invalidated.
Instrument calibration bench
• Norbar is currently the only laboratory accredited by UKAS for the calibration of Electrical Torque
Measuring Indicators.
• Before any calibration or recalibration the torque measuring device is preloaded three times in
succession to the maximum applied torque of the device. Each preload is maintained for between 1
and 11/2 minutes to exercise the device and stabilise it in the calibration fixture.
• The device is calibrated with at least five approximately equal steps from 20% to 100% of maximum
torque. Lower values are allowed as long as they meet certain criteria for resolution.
• For Classes 0.05 and 0.1, it is mandatory to calibrate the torque measuring device in four different
mounting positions each rotated 90º about the measurement axis. For all other classes the device is
calibrated at a minimum of two different mounting position at least 90º apart.
• Two series of readings are taken, and the device is then disturbed, generally by being disconnected
from the calibration fixture and rotated through 90 .The device is then preloaded once to full scale.
A third series of readings are then taken.This process is repeated until readings have been recorded
in all required orientations.
• If reversibility is required, a single series of decreasing torques are applied at the end of the last
increasing series.
• Should calibration be required in both directions, the series of readings are repeated in the opposite
direction.
• The calibration data is then analysed to establish the following parameters.
Repeatability
The variation between the indicated deflection from series 1 and 2, expressed as a percentage of the
mean of the two readings.
Reproducibility
The maximum variation between series 1, 2 and 3, or series 1, 2, 3, 4 and 5 expressed as a
percentage of the mean indicated deflection calculated from series 1, 3 or series 1, 3, 4, and 5.
Error of Indication
Where the results are expressed in units of torque, the errors of indication are the variation between
each applied torque and the mean indicated deflection at that torque.
Error of ero Torque
The maximum zero reading recorded after each loading series is expressed as a percentage of the
maximum mean indicated deflection.
92
Norbar - Total Torque Control
Measurement and Calibration
Error of Interpolation
Where the results are expressed in volts or units other than torque units, a 2nd order
polynomial equation (best fit line) is established and the difference in deflection from the
computed value is expressed as a percentage of the computed value.
Reversibility
The variation between the readings from the last torque series applied in an increasing
mode and the readings for the same given torque applied in a decreasing mode.
Reversibility is expressed as a percentage of the deflection of the last increasing series for
the given torque.
Calibration office
Classification
The parameters are each compared with a table to establish the device’s classification.
Class 0.05 is the highest performance, and class 5 is the lowest defined by the standard.
The overall class reported will be that of the lowest performing parameter. For example
reproducibility may be a class 1 when all other parameters meet class 0.5.The device will
be classified as 1.
• Additionally the uncertainty of measurement of the applied torque must be five times
better than the overall class reported. Norbar’s uncertainty of measurement (typically
0.02%) allows classification to Class 0.1 devices.
• Different classes may be quoted for ranges below 20% of maximum capacity.
