ALRE JDL-116

Differential pressure switch for monitoring overpressure, differential pressure, or underpressure of air and non-flammable, non-aggressive gases. Usable as an exhaust or fan monitoring device, or flow monitor to secure electric heating registers, as filter monitoring, air pressure deficiency protection, or limit controller. Note: If the differential pressure switch has switched a voltage above 24 V and a current above 0.1 A, the gold layer on the contacts will have burned off. 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 and must be ordered separately. Delivery includes the mounted mounting bracket JZ-10.
