Passive sensor FOT30
FOT 30 sensor has been specially designed to detect independent light sources: it detects the light emitted by them and compares its intensity with the threshold value set by a potentiometer. If this threshold is exceeded, the sensor detects that a light source is present in the monitored area and switches.
Sensitivity of the sensor can be pre-set by means of switches in 2 levels: 0-95 % or 95-100 % and thus adapted to different applications.
The sensor is available in IR or visible light versions and can also be used with fibre optics.

Application examples:
- Flame detection
- Part recognition in steel mills
- Spark monitoring in air exhaust ducts
