Description

FEMA pressure switches of the DCM (except DCM 1000, DCM 4016 and DCM 4025), VCM (except VCM 4156), VNM, DNS, VNS series and the differential pressure monitor DDCM (except DDCM 252, 662, 1602, 6002) can be equipped with 2 microswitches.

Standard equipment
The standard equipment of every two-stage pressure switch includes a switching device with 2 microswitches, both single-pole switching. Switch I monitors the low pressure, switch II the higher pressure. The setting ranges indicated in the data sheets for the basic types apply to the two-stage pressure switches as well. It should be noted that the switching differentials of the individual microswitches may not be exactly the same due to component tolerances.

Switching interval
The switching interval of the two microswitches is the difference (in bar or mbar) between the switching points of the two microswitches.
