Differential pressure switch mech,20-500Pa,5KPa JDW-5

Differential pressure switch mech,20-500Pa,5KPa JDW-5 – Alre-it – H530996 – 4050528045201: Differential pressure switch mech,20-500Pa,5KPa JDW-5 Suitable as monitor, max. operating pressure 50hPa, initial setting 0.02... 0.5hPa, medium temperature -15... 80°C, rated operating voltage Ue at AC 50 Hz 12.. 250V, rated operating voltage Ue at DC 12...24V, start value measuring range pressure 30Pa, end value measuring range pressure 500Pa, number of auxiliary contacts as NO contact 0, number of auxiliary contacts as NC contact 0, number of auxiliary contacts as changeover contact 1, design of the electrical connection screw connection, Number of NC contacts as main contacts 1, number of NO contacts as main contacts 1, degree of protection (IP) IP54, differential pressure switch for monitoring overpressure, differential or negative pressure of air and non-flammable, non-aggressive gases. Can be used as an extractor or fan monitor or flow monitor to safeguard electrical heating registers, as a filter monitor, low air pressure safety device or limit value 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 will have burned 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. Delivery without mounting bracket, can be screwed on directly (with 2 screws).
