2.0 INSTALLATION
Caution
Ensure that the LSP Linescanning Thermometer is mounted securely, in a location where the effects of
vibration, dust and fumes are kept to a minimum. Ensure that the scanning sight path is not obscured.
Choose a mounting location which minimises external heating of the scanner. If the ambient temperature
of the unit exceeds the specified maximum, a cooling system, available from Land Instruments, must be
fitted. The full range of Land cooling and purge accessories can be found in the Installation Accessories
section of this User Guide.
If the instrument is to be used in environments where gases resulting from combustion are present, it is
highly recommended that Land Instruments be contacted and the application fully assessed before any
installation takes place.
2.1 Introduction
The equipment specified in this User Guide must be operated, maintained and serviced by suitably trained
personnel, capable of carefully following the procedures, warnings and guidelines given. It is adviseable that all
User Guides and Installation Guides associated with LSP System equipment should be read thoroughly and be
kept readily available.
2.2 Positioning The Scanner
The scanner should be mounted taking careful note of the cautions described in section 2.1 and positioned so
that the target plane is parallel to the scanner window. The length of the scan line is proportional to the distance
between the scanner and the target plane. The target distance should be chosen to give a scan line that just
exceeds the width of the product, as this gives maximum spatial resolution.
The Scan Width may be found using the the following table or calculated by the formula:
SW = (D+ 35mm) x 1.68 or
SW = (D+ 1.38in) x 1.68 (where D= Target Distance)
The spot width (spatial resolution) at any distance is given by:
spw = 12mm / 0.5in @ <1200mm / 47.2in
spw = D/100 @ >1200mm / 47.2in
D(Target Distance) mm/in SW (Scan Width) mm/in
200/7.9 395/15.6
400/15.8 730/28.9
800/31.5 1405/55.2

Recommended maximum target distance = 3000mm / 118.1in

2.3 Alignment And Scan Direction
The Land LSP Linescanning Thermometer incorporates an integral laser unit (model dependent) to aid alignment
during installation. Details on the use of this feature are described in section 4.0. Where this laser alignment
feature is not available, precise alignment may be accomplished through the use of a mobile 'hot source', to
identify the plane and extents of the scan line. Alternatively, the intended target product may be used if this is
available during the installation process.
To interpret the scan profile produced by the scanner, it is necessary to determine the scan direction of the unit.
This is indicated by an embossed arrowhead cast into the top of the scanner casing. Once positioned, the design
of the scanner mountings ensure that the unit is replaced in the correct orientation, should the scanner be
removed from the application for servicing etc.
2.4 Installation Precautions
Vibration:
It is highly recommended that the LSP Linescanning Thermometer is positioned in a location where vibration is
kept to a minimum.
Infrared Reflections:
All practical targets have some reflectivity within the infrared waveband. This reflectivity increases as the target
emissivity (see section 5.0) reduces. Therefore the scanner sees some radiant heat energy from reflections of
surrounding objects as well as from the target source. This energy is not usually sufficient to have an effect on
the measurement, but care should be taken to ensure that objects of similar or higher temperature to the target
are not placed where reflected energy may enter the scanner.

3.0 SERVICES
3.1 Electrical Connections
The LSP Linescanning Thermometer requires just one electrical interface for normal operation. This interface
is made to the LSP Processor, via the interface cable (Land part no. 031.402) supplied with the system. The cable
is supplied pre-terminated at the scanner connection end, but the processor end is unterminated to allow the
cable to be cut to suit the application. The plug at the scanner end of the interface cable requires care when
making the connection to the scanner socket. Simply orientate the plug to suit the socket and press into place.
Do not force the plug into place. To remove the plug, grip the knurled sleeve section of the plug and pull upwards.
Termination details for the processor end of the interface cable can be found in the Land LSP Processor
Installation Guide.
Caution
The interface cable may be cut to length, but under no circumstances should an attempt be made to
extend the cable length beyond the 15m / 49.2ft maximum, by joining to a second length of cable. Failure
to comply with this instruction could result in incorrect operation of the instrument.
3.2 Water Requirements (Water-Cooled Units Only)
When the LSP Linescanning Thermometer is to be used in an environment where ambient temperatures are
above the maximum specified, the Land water cooled, air purge mounting accessory must be used. This requires
a constant water supply to be available. The special mounting plate has internal water channels with inflow and
outflow connections (G1/8 tappings) in the plate edge. There is no preferred flow orientation, however, if the
scanner is mounted in a position where one of the water connectors is higher that the other, the lower connector
must be used for the mains water in-flow.
The water-cooled mounting plate is supplied fitted with hose connectors suitable for 9.5mm / 3/8in bore water
hose. The water flow rate required will depend upon each individual application, but 1l/min / 0.26USgal/min is
an absolute minimum at 30°C / 86°F maximum water temperature.
Caution
Overcooling of the unit to below the local dewpoint, indicated by the formation of condensation, must
always be avoided. The temperature of the cooling water should ideally be in the range of
15 to 30°C / 59 to 86°F.
A clean, constant water supply is recommended, as this reduces the likelyhood of blockages within the
mounting plate.

User Guide
198.240
3.3 Air Requirements (Air-Purged / Cooled Units Only)
When the LSP Linescanning Thermometer is to be used in an environment where high concentrations of dust
are likely to be encountered, it is highly recommended that the Land air-purge mounting accessory should be
utilised. The mounting plate incorporates a cross flow purge for the scanner window. Although this will keep the
window free from dust particles, it will not however, clear the instrument sight path.
The air supply should be connected using the G3/8 threaded hole at the end of the mounting plate. If possible,
ensure that the air purge exit direction is downwards and ensure that this exit is not impeded by mounting
structures.
The air purge flow rate depends upon local conditions of the installation and scanner orientation, but a rate of
300 l/min / 12.36 ft³/min at an inlet pressure of 1m WG is typically sufficient.
An end plate air cooling accessory is available which is recommended for use in environments where the ambient
temperature is in the range of 60 to 80°C and the application prevents the use of water cooling.
Caution
Ensure that the quality of the air supply is high and that it is dry and free from oil, otherwise permanent
damage may occur.

4.1 Using The Laser Alignment Tool (Model Dependent)
Ensure that all CLASS 2 Laser Safety Warnings are adhered to at all times when the laser alignment tool is in
use.
Depress the Laser Alignment button which is positioned adjacent to the scanner interface connector on top of
the scanner body. The scan speed of the instrument reduces to approximately 1Hz and the Laser Alignment
button flashes to indicate that the laser is active. A red stripe of laser light is projected through the window of the
scanner, indicating the position and extents of the scan line. Adjust the scanner position as required to ensure
that the product almost fills the scan width.
Note
When the Laser Alignment facility is active, the scanner unit does not indicate target temperature.
To disable the Laser, press the flashing Laser Alignment button. Once pressed, the scanner stabilises for
approximately 60 seconds, then the unit begins normal operation and temperature information is available.
Alternatively, the Laser Alignment facility may be operated remotely from the LSP Processor. (See LSP
Processor User Guide for details of remote operation.)
