Housing colour: black Monitoring of overpressure, differential

or under-pressure of air and

incombustible, non-aggressive gases.

Exhaust or fan monitoring or fl ow

monitor for securing electrical heat

registers, as fi lter monitoring, air

pressure shortage safeguard, limit

value controller.

JDW- … : Supplied without mounting

bracket; can be screwed on directly

(with 2 screws).

JDW- … Z: Supplied with attached

mounting bracket JZ-10.

JDL … : Supplied with attached

mounting bracket JZ-10.

Note: Once the differential pressure

switch has connected a voltage >

24 V and a current > 0.1 A, the gold

layer at the contacts will have burnt

away. Thereafter, the differential

pressure switch can only be operated

at this or a higher power.

Note: The hose set is not a part

of the delivery scope and must be

ordered separately.
