DISTANCE AND SPOT SIZE
The size of the area (spot size) to be measured determines the distance between the sensor and
the target. The spot size must not be larger than the target. The sensor should be mounted so
that the measured spot size is smaller than the target.
AMBIENT TEMPERATURE
The sensor is designed to operate in ambient temperatures from 0°C to 75°C.
Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient
temperature.
ATMOSPHERIC QUALITY
Smoke, fumes or dust can contaminate the lens and cause errors in temperature measurement.
In these types of environment the air purge collar should be used to help keep the lens clean.
ELECTRICAL INTERFERENCE
To minimise electromagnetic interference or ‘noise’, the sensor should be mounted away from
motors, generators and such like.
MECHANICAL INSTALLATION
All sensors come with a 1.5 m USB cable and a mounting nut. The sensor can be mounted on
brackets, clamps or cut outs of your own design, or you can use the fixed and adjustable
mounting bracket accessories which are shown below.
AIR PURGE COLLAR
The air purge collar below is used to keep dust, fumes, moisture, and other contaminants away
from the lens. It must be screwed in fully. Air flows into the 1/8” BSP fitting and out of the front
aperture. Air flow should be no more than 5 to 15 litres/min.
Clean or ‘instrument’ air is recommended.
