Non contact temperature measuring systems are designed for
continuous quality and process monitoring and control in a wide
range of industries. They can be used in a variety of applications
such as metal production, processing, foundry and forging, glass,
electronics, mineral processing and petrochemical where
accurate measurement of temperature is vital.
No other method of temperature measurement offers the
benefits of non contact infrared radiation thermometry.
• Infrared radiation thermometer systems measure continuously
the temperature of hot, moving or normally inaccessible
materials accurately and safely at a distance.
• Sensing heads do not require contact with the target object,
and therefore cannot interfere with, damage or contaminate
the product they are measuring.
• Thermometers do not remove heat or disturb the process
being monitored and offer the only solution when the product
is small, fragile or in a vacuum or controlled atmosphere.
SYSTEM 4 gives you a wide choice of compatible items to ensure
the system you buy is optimized to meet the needs of your
application, budget and environment.
LANDMARK® processors are designed to produce the process
control variables you need from ANY of the SYSTEM 4 sensors.
With this total compatibility, you are free to choose a processor to
give the features and performance you need and select the
sensor type best suited to the application. All SYSTEM 4
processors and sensors are calibrated individually to guarantee
interchangeability and hence easy maintenance for many years.
SYSTEM 4 offers an extensive, and expanding, range of
Standard and Fibroptic thermometers, designed to cover all
industrial non contact temperature measurement applications.
PROCESSORS
The heart of any temperature measurement system is the signal
processor. A LANDMARK® signal processor puts the controls of
your system where you need them - panel mounted or DIN rail
mounted, the choice is yours. SYSTEM 4 uses high speed
inputs, real time signal processing and flexible outputs to
convert the output of each sensor into real process variables.
LANDMARK® GRAPHIC is the state-of-the-art, panel mounted
signal processor, designed to control and process data from any
SYSTEM 4 Thermometer. The Multi-channel processor accepts,
processes and displays inputs from any combination of up to four
separate thermometers simultaneously - it is not multiplexed.
Multiple outputs are provided which can be integrated directly
into any process monitoring, recording or control system.

accessories which provides protection and accurate alignment for
both Standard and Fibroptic thermometers. All mountings permit
quick and tool-free installation and removal of
thermometers, keeping downtime to the absolute minimum.
Infrared radiation thermometers do not require contact with the
target object, so they cannot interfere with, damage, or
contaminate the product they are measuring. They do not
remove heat or disturb the process being monitored and offer the
only solution when the product is moving, small, fragile, or in a
vacuum or controlled atmosphere.
SYSTEM 4 Thermometers all feature temperature spans and
operating wavebands selected to ensure optimum accuracy of
measurement for each application.
Any SYSTEM 4 thermometer, selected from the extensive range
available, can be used with any SYSTEM 4 LANDMARK®
processor, allowing you to build a temperature measurement
system designed specifically to your application requirements.
Standard thermometers feature precision through-the-lens
focusable optics which guarantee exact viewing and accurate
measurement of the smallest of target areas.
Single wavelength thermometers are intended for both general
purpose use as well as solving problems in specific applications.
Fibroptic thermometers are used to measure the temperature of
materials where the target is difficult to access, and where high
temperature or high magnetic fields prevent the use of other
types of sensor.
Ratio thermometers are used in difficult environments containing
steam, smoke, or dust, or where the target is small or does not
completely fill the field of view.

Display
The processor can control all types of SYSTEM 4 thermometer
simultaneously (i.e. M1, R1, M6 etc.). The thermometers can
have differing temperature ranges and even units (°C or °F).
Each channel has identical features to the single channel version;
two analog outputs; a fully scaleable 0 to 20 or 4 to 20mA output,
and a 1mV/° output. Two alarm outputs, both either High or Low
activated, each with changeover relay, are provided on every
channel card.
MATH FUNCTIONS
The unique multi-channel capability of the LANDMARK®
GRAPHIC makes possible the, also unique, Math Function
option. The processor accepts and compares up to four
thermometer signals. The results are then output to the process
control instruments in the form most suited to their requirements.
Two independent math functions are provided, each can
calculate, display and output either the Maximum, Minimum,
Mean, Difference or Range of temperatures measured by the
selected thermometers in your system.
The Expanded Span function allows you to extend the span of
your temperature measurement system from the minimum
temperature of the thermometer with the lowest temperature
range, to the maximum temperature of the thermometer with the
highest temperature range.
Any SYSTEM 4 Thermometer can be used in conjunction with the
Math Functions. Up to four SYSTEM 4 Thermometers can be
connected to the processor and two Maths Functions can be
configured. There are many different options for each Math
Function, the same option can be selected for both functions if
required.
Typical Expanded Span display
Each Math Function is fully independent from the other, and both
are independent from the four individual thermometer
temperature output channels, standard to the Landmark Graphic
Processor. Each function has both a current output, either 0 to
20mA or 4 to 20mA, and a single relay alarm output.
Math Functions have an almost unlimited range of uses in applications
such as trending, cross-product uniformity, hot edge detection etc.
SERIAL COMMUNICATIONS
RS232C and RS485 serial communications are included with the
Math Function option for the LANDMARK® GRAPHIC processor.
A serial option is also available for users who do not require
Math Functions.
Serial communications provide a remote interface between the
processor and the process control computer. The serial
communications circuitry connects directly to the internal
microprocessor, via which it has access to all the data in the
LANDMARK® GRAPHIC.
A single option card can input any parameter for any fitted channel
card, and retrieve all existing settings along with the temperature
data and system status information for any fitted channel card.
EASY CONFIGURATION
LANDMARK® GRAPHIC is easy to configure using the text
based, setup menu system which is switch selectable in different
languages; English, French, German, Italian, Spanish and
Japanese. Once the thermometer type has been entered, the
processor automatically configures the appropriate input data.
You can then select the required temperature span for the output
current range, target emissivity/non greyness values and a
range of time functions and alarm settings to match your exact
needs.
All parameter settings are entry code protected.
Customer connections are also made as easy as possible, using
two-part demountable terminal strips located on the rear panel.
The modular construction of SYSTEM 4 ensures that any system
expansion is catered for with ease.
GRAPHICAL DISPLAY AND KEYPAD
The LCD panel features a large 320 x 240 pixel display, providing
a high quality visual interface with the system.
The tactile keypad enables easy configuration of the processor
with thermometer and process variables.

measured temperature in numeric or graphic formats, presenting
useful profile or trending data. The LCD panel provides a choice
of numeric, line chart, deviation chart or mixed displays.
Inputs from up to four individual thermometers can be displayed
simultaneously as 4 channel numeric, 4 channel bar graph or 4
channel deviation bar graph.
REAL TIME PROCESSING
A fully featured and real time Peak Picker is used when
measuring the temperature of intermittent targets, or where the
hot target surface is obscured by cool areas such as scale on
rolled steel.
Landmark® Graphic Processor display and keypad
Fast input sampling by the Peak Picker, combined with a built-in
spike protection filter allows the processor to respond quickly to a
rise in temperature signal from the thermometer.
The user settings also includes a threshold value which, together
with On/Off delay timers and two distinct modes of operation,
allow configuration to deal with the most demanding of
applications.
An Averager is used to smooth any rapid fluctuations in the
process value or reading to deliver a stable, time-averaged value
for process control.
The time constant is selected from 0 to 512 seconds, to give
suitable, gradual changes in the temperature display and
processor output.
If your process is intermittent or interrupted, a Track and Hold
function is provided which allows you, via an external command
signal, to Hold the required measurement value until you wish to
once again Track the variations in the process.
ALARMS
Two alarms are provided, selectable as either high or low, and
are ideal for use as ON/OFF controllers. Alarm thresholds are

M8 thermometers measure from 0 to 1000°C and are ideal for
applications such as food, textiles, paper and plastics. They operate
at a waveband which avoids the effects of atmospheric absorption.
R1 Ratio Thermometers
R1 Ratio Thermometers are intended for difficult, high temperature
applications where the field of view is not fully filled or where the
sight path is obscured. Their range is 600 to 2600°C and can
accurately measure temperature of targets with up to 95%
obscuration.
FIBROPTIC THERMOMETERS
Fibroptic models have a flexible fibre optics light guide which
enables the detector and electronics enclosure to be located in a
less hostile environment.
Fibroptic M1 Thermometers
Fibroptic M1 thermometers measure from 600 to 2600°C and
combine the flexibility of fibre optics with short wavelength
operation. They can be used in high temperature applications such
as metals, glass, coke ovens and induction heating.
Fibroptic M2 Thermometers
Fibroptic M2 thermometers are designed for applications from 300
to 1100°C, such as glass mould temperatures where access to the
target is restricted, or limited to a few milliseconds.
Fibroptic M3 Thermometers
The Fibroptic M3 thermometers is designed for low temperature
applications, with low or uncertain emissivity, such as secondary
metals, within the range 50 to 250°C.
Fibroptic R1 Ratio Thermometers
Fibroptic R1 ratio thermometers measure from 600 to 2600°C and
provide accurate high temperature measurement of small
intermittent targets, such as rod and wire, and tube welding. Other
typical applications include kilns and vacuum furnaces.
THERMOMETER MOUNTINGS AND ACCESSORIES
To enable you to measure temperature
accurately in even the most severe
operating conditions, a complete range
of thermometer protection and
mounting accessories is available.
Full mechanical and thermal protection for the thermometer and
electrical connections is ensured, giving undisrupted service with
minimal maintenance in almost any environment.
JACKET
The corrosion resistant thermometer jacket provides air or water
cooling where excessive heat may exist.
The jacket allows quick, no-tools thermometer installation and
removal and ensures reproducible alignment.
END CAP
The end cap provides protection for the rear of the thermometer.
The ingenious design, featuring a pre-wired thermometer
connector and a terminal strip inside the end cap simplifies
customer connections on-site.
MOUNTING PLATES
Mounting plates enable the thermometer, together with a jacket,
purge and sighting tube, to be securely mounted in a safe
position to monitor the product or process.
O/N/M mounting plate is a simple, rugged mounting which can be
used with all of the sighting tubes.
O/N/AF adjustable mounting
plate is for use where accurate
sighting is essential. The
jacket/ purge fastens to an
adjustable circular plate. The
O/N/AF mounting is used with
the FS6 and FS36 sighting
tubes.
FIBROPTIC MOUNTINGS AND ACCESSORIES
THERMOMETER CONNECTOR
QUICK-RELEASE AND AIR PURGE ASSEMBLY
The thermometer connector is normally supplied pre-wired and
terminated in the end cap. A connector pre-wired to 4m of cable
must be ordered if the user does not require an end cap for the
application.
The quick release and air purge/sighting tube assembly attaches
to the optic head of the fibroptic thermometer to keep the lens
clean.
AIR PURGE
Extensive research has resulted in a highly efficient air purge
which keeps condensation, dirt and other deposits off the
thermometer lens. The air purge also helps to disperse fumes
and smoke from the thermometer sight path.
The purge accepts a range of air entry adapters and fittings, and
has the added bonus of being suitable for use with both fan or
compressed air supplies.
The front flange of the purge also mounts directly onto the Land
System 3 range of mounting plates and sighting tubes.
SIGHTING TUBES
The assembly can be used with a range of mounting
accessories.
MOUNTING PLATE
ASSEMBLY
A simple, robust 127mm diameter
mounting plate and quick release/air
purge assembly permits a range of
mounting options.
ANGLE MOUNTING BRACKET ASSEMBLY
A simple mounting bracket serves as an inexpensive mounting for
the thermometer optic head. The bracket is designed for bolting
to almost any mounting surface.
A range of Silicon Carbide, Sillimanite and Stainless Steel
sighting tubes are available in various lengths up to 1200mm for
use in temperatures up to 1550°C.
ADJUSTABLE MOUNTING FLANGE ASSEMBLY
Open ended sighting tubes (Type STO) are used to ensure a
clear view of a solid target through flame, smoke, fumes and dust.
Closed-end sighting tubes (Type STC) are used to measure the
temperature of a fluid material.
ADJUSTABLE MOUNTING PLATE
The adjustable mounting flange and quick release/air purge
assembly provides accurate alignment of the optic head.
An adjustable mounting flange allows alignment of the optic head
at any angle up to 45°.

THERMOMETER MOUNTINGS AND ACCESSORIES
Both the Standard bodied and Fibroptic range of mounting
accessories are subdivided into three groups which cover all
environmental conditions i.e. INDUSTRIAL, NON-HOSTILE and
LABORATORY.
NON-HOSTILE
Where the environmental conditions which apply to the
measurement application are less severe.
INDUSTRIAL
To be used where severe or extreme environmental conditions
prevail.
No adverse environmental conditions prevail, a requirement for
thermometer mounting only.
