Pressure switches Ex-DCM and Ex-DNM HONEYWELL / FEMA can be installed directly on the pressure line (pressure gauge connection) or on a flat surface with two 4mm Ø screws.
The maximum medium temperature at the pressure sensor must not exceed the permitted ambient temperature at the switching device. Higher medium temperatures are possible provided the above limit values for the switching device are ensured by suitable measures (e.g. siphon).
