Differential pressure switch for monitoring overpressure, differential pressure, or underpressure of air and non-flammable, non-aggressive gases. Can be used as a fume cupboard or fan monitor or flow monitor to protect electrical heating coils, as a filter monitor, air pressure deficiency protection, or limit controller. Note: Once the differential pressure switch has switched a voltage > 24 V and a current > 0.1 A, the gold layer on the contacts is burnt away. After that, the differential pressure switch can only be operated with this or a higher power. Note: The hose set JZ-06 / 1 is not included in the scope of delivery and must be ordered separately.
