These operating instructions are a part of the equipment. The
manufacturer reserves the right to change performance-, spe-
cification- or technical data without prior notice. Please keep
these instructions for future reference.
1.1 Intended Use
The operating instructions apply to MDSxxx series mechanical
pressure switches.
The pressure switches are used to monitor the pressure in a
fluid system under normal ambient conditions. As elec-
tromechanical signal converter they convert the pressure into
electrical signals with high precision. They detect pressure
ranges from 0.5 bar to max. 320 bar in different combinations.
Depending on the version, the process connection is a G1/8" or
G1/4" external thread, a G1/4" internal thread, or a flange (VF).
They connect to power via M3 cubic plug (DIN EN 175301-803)
or M12x1 plug (electric line box not included).
