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.
