There is a choice of thermometer type to match your temperature
requirements and process.
Single wavelength thermometers are intended for general purpose
use as well as solving problems in specific applications.
Ratio thermometers are used in difficult environments containing
steam, smoke, or dust, or where the target does not completely
fill the field of view.
Fibroptic thermometers are used to measure the temperature of
materials where the target is difficult to access.
The use of fibre optics is most effective in high temperature, high
magnetic fields etc. which would prevent location of other sensors.
SYSTEM 4 THERMOMETERS
SYSTEM 4 comprises an advanced range
of high precision radiation thermometers,
LANDMARK® processors and a range of
mounting accessories which combine to
form a complete temperature
measurement system.
SYSTEM 4 thermometers offer exceptional
flexibility with a choice of single
wavelength, ratio, fibroptic and fibroptic
ratio models.
Typical System
Thermometer type, temperature range, spectral
response and optical characteristics are chosen to suit
any application from 0 to 2600°C.
• Focusable optics - standard and short focus versions
with through-the-lens sighting providing clear and
guaranteed definition of target
• Optional close-up lenses - giving measurement of
targets as small as 0.45mm
• Accurate, reliable, drift-free measurement
• Rugged design with a range of mounting options
• Flexible fibre optics light guide versions - with optional
laser targeting system to define target spot
• High level linear output
RADIATION THERMOMETERS
Standard Bodied Thermometer
Fibroptic Thermometer
Proven, reliable electronics and a high quality optical system
combine to give a thermometer which delivers accurate,
dependable temperature measurement. A rugged die-cast
aluminium body, with a high quality electrical connector, ensures
reliable performance.
Standard bodied thermometers all feature through-the-lens
sighting with a 6° field of view. Adjustable focus with a circular
graticule gives precise alignment on to the smallest of targets. Two
optical variants are available: Standard focus - adjustable
between 500mm and infinity, and Short-focus - viewing from
350mm to 1m. Close-up lenses are also available which can
measure targets as small as 0.45mm from as close as 90mm.
FIBROPTIC THERMOMETERS
The use of flexible fibre optics light guides allows the detector and
electronics enclosure to be located in a less hostile environment,
and enables access to difficult targets.
The fibroptic thermometers are available with an optional integral
laser targeting system which defines the target spot for accurate
alignment.
The use of fibre optics permits viewing of normally inaccessible
targets, where there are high magnetic fields or in high ambient
temperatures up to 200°C without cooling of the optic head. There
is a choice of three optic heads and three light guide lengths.

OVERVIEW
For over 50 years, Land have been the
world leaders in delivering solutions to
temperature measurement problems.
The new family of products, combining
unrivalled expertise and design knowhow with the latest technology is...
SYSTEM 4 gives you a choice of
products which covers all applications,
environments and budgets, ensuring
premium performance at competitive
prices. Compatibility and
interchangeability of each product
ensures maximum flexibility, both at
time of purchase and subsequently for
easy maintenance.
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.

THERMOMETERS
SYSTEM 4 includes an extensive range of mountings and
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.

MULTI-CHANNEL CAPABILITY
The Multi-channel version of the LANDMARK® GRAPHIC
processor provides up to four fully featured and independent
temperature measurement systems in one package.
Any SYSTEM 4 Thermometer can be connected to any input
channel of the processor. Each channel is fully independent of
the other, the inputs are not multiplexed. Additional channels
may be added as required without affecting existing settings.

4 to 20mA
Output
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.
Help and error messages simplify setup and operation.
The cold cathode back-lit LCD panel provides a display of
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

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°.

WINDOW ASSEMBLY AND SIGHTING TUBES
Sighting Tube Information
Sighting Tubes
Sighting tubes are made from metal or refractory materials and
are either open ended (Type STO) or closed (Type STC).
Type STO tubes are used when viewing a solid target through
flame, smoke, fumes etc. The closed end of the type STC tube
is used as the target. A thermometer used with an STC tube
can replace a sheathed thermocouple.
To attach the sighting tubes to a mounting plate a steel adapter
(Type STA) is cemented into refractory sighting tubes.
The STA is drilled to fit the studs on the mounting plate
(O/N/M).
Replacement Sighting Tubes can be purchased without the
STA adapter fitted. Contact Land Infrared for details.
There are 3 types of tube material with varying lengths.
For exact dimensions and ordering references please refer to
the table adjacent.
Type
Silicon Carbide Tubes (STO & STC)
These are either open ended or closed, and can be used in
temperatures up to 2700°F/1500°C. They have high mechanical
strength, good resistance to thermal shock and very high
thermal conductivity.

AIR SUPPLY SYSTEMS
Air purges use a stream of air to disperse dust and fumes from
the thermometer sight path and to prevent dirt settling on the
lens or window.
Clean dry air must be supplied to the purges, and jackets with
integral purge and a diffuser.
Any foreign material in the air supply will potentially block the
diffuser, reduce the purge efficiency and deposit material on
the lens or window.
To achieve the necessary cleanliness standards, the air
system should be designed to recommended guidelines.
A filter system should be fitted in every air line which feeds a
purge.
LAND can supply an automatic drain air filter system with
optional low flow alarm for use with correctly engineered
compressed air systems.
A relatively clean, dry compressed air supply of 25 to 150 lb/
in²/1.75 to 10.5 kg/cm² is required for use with the system
A/A air filter system.

System A/A (LF and HF)
There are two types of restrictor available; low flow (LF) and
high flow (HF). Low Flow (LF) is for use when only purging is
required, the high flow (HF) when both purging and cooling are
required.
The optional flow alarm detects a low flow rate. This can be
linked to a warning device i.e. Klaxon or annunciator lamp to
alarm once the flow falls below the required rate.
