ALRE JDL-112

Differential pressure switch for monitoring overpressure, differential pressure, or underpressure of air and non-flammable, non-aggressive gases. Usable as exhaust or fan monitoring, or flow switch for securing electric heating registers, as filter monitoring, air pressure deficiency protection, or limit controller. Note: If the differential pressure switch has switched a voltage over 24 V and a current over 0.1 A, the gold layer on the contacts has 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.
