3. Operating principle and precautions
a．Principle of infrared temperature measurement
Any object will emit infrared energy externally and radiation intensity changes with temperature. The Infrared Two Laser Temperature Sensor IRT-LAS.01-500A series is usually used for measuring infrared radiation energy which wavelength is within 0.8μm－18μm.
Infrared Two Laser Temperature Sensor IRT-LAS series is a photoelectron sensor which receives infrared radiation and converts it to electrical signal, displays or outputs temperature by linear signal processing by line amplifier.
b．Maximum distance and size of measurement point
Size of measurement target and optical features of infrared thermodetector determine maximum distance between measurement target and measurement head. To prevent measurement error, the measurement target should fill field of view of probe as much as possible. Therefore, always keep measurement point smaller than measurement object or at least the same size as measurement target.
c.Environment temperature
Series IRT-LAS infrared thermodetector can work within environment temperature 0--50℃, otherwise use cooling protection jacket.
d.Cleaning lens
Keep instrument lens clean and prevent measurement error or damage or lens caused by dust or smoke. If there is dust accumulated on the lens, wipe it clean with lens wiping paper dipped with anhydrous alcohol.
e.Electromagnetic interference
To prevent electromagnetic interference, please take the following measures:
The Infrared Laser Temperature Sensor should be installed in a place away from electromagnetic field (such as electric motor, motor and high power cable). Add metal sleeve is necessary.

4. Installation
a. Mechanical installation
Series LAS metal housing has M18×1 thread which can install directly or use installation support. The adjustable installation support makes it easier to adjust measurement head.
When adjust measurement target and measurement head, ensure that optical path is barrier free, as shown below:
