Spark Detector FM 1/8

Spark detection preferably in dark areas

Spark detectors FM1/8 can be used in dark areas where ambient light is not present. This ensures the high sensitivity of the FM 1/8 sensors so that the detection of ignition sources can be optimized even in dense matial flow. The optics of the sensors are normally kept clean by the air and material flow which makes the system easier to maintain.

Air purge adapter

If dirt accumulation or other build-up on the sensor optics is expected, special air purge adapters increase the detection reliability. Cleaning intervals are thus extended.
