4.1 Allgemeines
Der Druckschalter dient innerhalb von
explosionsgefährdeten Bereichen zur be-
triebsmässigen Druckregelung.
Für den Einsatz ist zwingend eine Ex-i
Trennbarriere mit ATEX Bescheinigung
[Ex ia] IIC erforderlich.

4.1 General points
Pressure switches are used for controlling
the pressures in potentially explosive atmos-
pheres. The pressure switches are designed
for stationary installation only.
