Using the infrared radiation heating, the probe of absorb radiant energy caused by temperature sensitive element, and then makes some relevant physical parameters change, by measuring the change of physical parameters to determine the infrared radiation received by the detector.Send Inquiry
This system is based on the principle of operation triangle infrared existing detecting.The crosspoint of emission ray and receive ray is the max detection scope.
In order to adapt the background of detector, the working system is combined with the background rejection mode. Relevant backgroud will be detected but be ignored. In the detection process, only the reflection of detection area will be received. (Background rejection of humidity,ground will not be received.)
Background rejection techique:
--protection for the moving objects.
-- No affection of the background factors.
