6.1 Recommended Installation Arrangement
The location of the IQ thermometer should be carefully chosen, such that it is
easily accessible and in a position not unnecessarily exposed to heat, fumes
or liquid spray. The sight path between the IQ thermometer and the target,
should be as free as possible from smoke, liquid spray and from the intrusion
of machinery. The axis of the thermometer should be at right angles to the
target surface, however, an angle of up to 45° from the normal is acceptable.
If the thermometer to be installed is a monochromatic or single wavelength
variant (SN1 etc), it must be positioned such that at the chosen target
distance, the field of view of the thermometer is completely filled. The target
size required to fill the field of view can easily be determined, according to the
lens configuration and the distance of the thermometer from the target (see 'IQ
Thermometer Sighting').
IQ Thermometer Installation
1. Choose a suitable location for mounting the thermometer. The following
criteria should be considered when making the choice:
•
If the installation area is not clean or free from dust, smoke or water
spray, then a Land air purge system must be utilised to ensure that the
thermometer lens is kept free from such airborne contaminants. Ensure that
a suitably conditioned air supply is available.
•
If the surrounding ambient temperatures of the installation area are outside
the thermometer specification, then a Land air or water cooled protective
jacket must be utilised to ensure that the thermometer operates at the
specified ambient temperature. Ensure that a suitably conditioned air or
water supply is available.
2. Position and mount any required thermometer mountings and/or
accessories.
3. Configure the thermometer lens and spacers to match the application (see
'Thermometer Sighting').Ensure that the selected ring configuration allows
correct focusing of the thermometer onto the target.
4. Configure the thermometer to match the application.
5. Fit the thermometer to the mountings. Ensure that the services, where
required, are running and are fully operational before installing a
thermometer into a hostile environment. Ensure that the thermometer lens
is clean, free from contaminants and unobstructed.
6. Apply power to the thermometer. If the thermometer has a laser alignment
facility, this can be utilised to ensure that the thermometer field of view
aligns with the target area. The laser function can be operated by the
following methods:
•
By the laser activation button on the rear of the thermometer
•
By the laser activation button on the front of the SN-W/E interface unit
•
From within the configuration software or web interface
•
By remote manual switch, wired into the SN-W/E interface unit (user
supplied)
7. Ensure that the thermometer is operating correctly. Any configuration
changes can be made via the configuration software or web interface facility.
8. Carry out the following recommended pre-operational checks:
•
Ensure that all relevant services are functioning correctly, with no apparent
