Safety
Intended use
The BTL7 Micropulse Transducer together with a machine
controller (PLC) comprises a displacement measurement
system. It is fitted into a machine or piece of equipment for
its application. Flawless function in accordance with the
specifications in the technical data is ensured only when
using original BALLUFF accessories, and use of any other
components will void the warranty.
Opening of the transducer or non-approved use are not
permitted and will result in loss of warranty and void any
liability claims against the manufacturer.
2.2
General safety notes for the transducer system
Installation and startup are to be performed by trained
technical personnel only.
The operator is responsible for ensuring that local safety
regulations are observed.
In particular, the operator must take measures ensure that
a defect in the displacement measurement system will not
result in hazards to persons or equipment.
When defects and non-clearable faults in the transducer
occur, take it out of service and secure against unauthorized use.

2.3
Meaning of the warnings
Note!
The pictogram used with the word "Caution"
warns of a possible hazardous situation affecting the health of persons or equipment damage.
Ignoring these warnings can result in injury or
equipment damage.
► Always observe the described measures for
preventing this danger.

Construction and function (cont.)
Function
3.3
The BTL7 transducer contains the waveguide which is
protected by an outer stainless steel tube (rod). A magnet
is moved along the waveguide. This magnet is attached to
the moving member of the equipment whose position is
being determined.
LED indicator
LED 1
LED 2
The magnet defines the position to be measured on the
waveguide.
An internally generated INIT pulse together with the magnetic field from the magnet generates a torsional wave in
the waveguide through the magnetostrictive effect which
propagates along the waveguide at ultrasonic velocity.
The component of the torsional wave which arrives at the
end of the waveguide is absorbed in the damping zone to
prevent reflection. The component of the torsional wave
which arrives at the beginning of the waveguide is converted by a coil into an electrical signal. The travel time of
the wave is used to calculate the position. Depending on
the BTL7 version, this information is made available as a
voltage or current with rising or falling gradient.
The following functions can be selected for the output
values:
– Position
– Velocity (with or without sign)
– Differential position
2 outputs are provided which can be allocated independently of each other. 2 magnets may be used.
The entire range of functions can only be
configured using the "Micropulse Configuration
Tool" PC software. For this the USB communication box must be connected (see Accessories on page 23). The transducer can be calibrated without PC software by using the
calibration device (see page 14 ff).

Fig. 4-1: Installation variants in non-magnetizable material
Magnetizable material
When using magnetizable material, the transducer must be
protected from magnetic disturbances by suitable means
(e.g. spacer ring made of non-magnetizable material,
sufficient distanced from strong external magnetic fields).
Horizontal mounting: For horizontal mounting with
nominal stroke lengths > 500 mm we recommend fastening the tube at its end (only possible for Ø 10.2 mm tube)
or supporting it.
Hydraulic cylinders: When installing in a hydraulic cylinder, be sure to keep the minimum value for the hole diameter of the piston (see Tab. 4-1).
Threaded hole: The transducer comes with an M18×1.5
(ISO) or 3/4"-16UNF (SAE) mounting thread. Depending on
the model, the threaded hole must be prepared before
installation.

Installation (continued)
Installing the transducer
Note!
Improper installation can compromise the
function of the transducer and result in
increased wear.
► The flange surface of the transducer must
make full contact with the mounting surface.
► The hole must be perfectly sealed (O-ring/
flange gasket).
► Construct threaded hole (and, if needed, recess for the
O-ring) as per Fig. 4-3 and Fig. 4-4.
► Thread the transducer into the threaded hold (max.
tightening torque 100 Nm).
► Install magnet (accessory).
► Nominal stroke length 500 mm or longer: Fasten rod at
its end (only possible for 10.2 mm rod) or support it.
Appropriate nuts for the mounting thread are
available as accessories (see page 22).
4.3.1 Installation recommendation for hydraulic
cylinders
When sealing the hole using a flat gasket, the max. operating pressure is reduced based on the larger surface subjected to pressure
The slide element may be threaded or glued on.
► Secure the screw from loosening or becoming
detached.
► Use a suitable glue.
Slide surface
Flow gap
Piston rod
BTL outer rod
Slide element
Fig. 4-6: Detail view and top view of slide element
There must be a sufficient gap between the slide element
and the piston hole to allow for the flow of hydraulic fluid.
Methods of attaching the magnet:
– Screws
– Threaded ring
– Press-in
– Indentation (center punching)
The hole in the spacer must be matched to the slide
element for optimal guiding of the protective tube.
Magnet
Magnet attachment
For horizontal installation in hydraulic cylinders (nominal
stroke lengths > 500 mm) we recommend using a slide
element.
Detailed dimensioning is the responsibility of the
cylinder manufacturer.
The slide element material must be matched to the load
situation, the medium used and the relevant temperatures.
Possible materials include Torlon, Teflon or bronze.

Shielding and cable routing
5.3
Defined ground!
The transducer and the control cabinet must be
at the same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC) observe the
following:
– Connect transducer and controller using a shielded
cable.
Shield: Braided copper shield with minimum 80%
coverage.
– Connector version: Area connection of shield in connector with the connector body.
– Cable version: Connect cable shield to housing on
transducer side.
Ground cable shield on controller side (connect to
protection ground).
Magnetic Fields
The transducer system is a magnetostrictive system.
Ensure that there is sufficient distance between the transducer and between the holding cylinder and strong, external magnetic fields.
Note!
When starting up and if the displacement
measurement system is part of a closed loop
system whose parameters are not yet set, the
system may exhibit uncontrolled movements.
This could result in personal injury and equipment damage.
► Startup should be performed only by trained
technical personnel.
► Observe safety instructions of the equipment or system manufacturer.
1. Check connections for tightness and correct polarity.
Replace damaged connections.
2. Turn on the system.
. Check measured values.
Especially after replacing the transducer or after repair
by the manufacturer, check for correct null point and
end point values. If necessary recalibrate the transducer (see page 13 ff).

Cable routing
Do not route the cable between the transducer, controller
and power supply near high voltage cables (inductive stray
noise is possible).

Setting using the calibration device
Calibration device
Automatic deactivation!
If the buttons on the calibration device are not
pressed for approx. 10 min., the Programming
mode is automatically quit.
The calibration device is an ancillary unit for setting the
transducer when it is not possible to configure it with PC
and software.
Requirements
– Button function is unlocked by the PC software (button
lock).
– The calibration device is in place.
– The transducer is connected to the system controller.
– Voltage or current values from the transducer can be
read (using a multimeter or the system controller).
Values for null and end point
– Any desired position of the magnet can be used as the
null or end point. The null and end points may not however be reversed.
– The absolute null and end points must lie within the
minimum or maximum limits of what can be output.
– The distance between the null point and end point
must be at least 4 mm.
If the button function is locked, the lock must
be lifted using the PC software.
The last set value are always saved, regardless
of whether the setting was made using the
buttons or automatically after 10 min. have
expired.
Settings
The transducer has the following factory settings which
can be adjusted using the calibration device:
– One magnet,
– "Position" function on both outputs, Output 1 with
rising curve and Output 2 with falling curve,
– Identical measuring range for both outputs.
During setting the start and end points for both outputs are
set the same. No other function may be selected and no
additional magnet used.
If the button function is locked, the lock can only be lifted if
these conditions are met.
