All Sensors at a Glance Spark Detection under Daylight Conditions

GreCon can detect sparks on conveyor belts,
There are different risks of fi re and explosion in industrial production lines, or at transfer points
processes. GreCon has suitable detectors for different risks. between conveyor systems. A special
sensor, type DLD 1/8, is used where
ambient light is present.
Spark Detection Preferably in Dark Areas

Spark detectors FM 1/8 can
be used in dark areas where
ambient light is not present. This

reliability is achieved by using three detection elements per
sensor. The fi ber optic cables are available in different lengths
for different duct diameters.
