DCM/DNM

Pressure switches and pressure monitors for overpressure

This universal pressure switch can be used in

general mechanical engineering and the printing

machine industry, as well as in pneumatics and

hydraulics.

SIL 2 according IEC 61508-2

Technical data

Pressure connection

External thread G 1/2 (pressure gauge

connection) according to DIN 16 288 and inter-

nal thread G 1/4 according to ISO 228 Part 1.

Switching device

Robust housing (200) made of seawater-

resistant diecast aluminium GD Al Si 12.

Protection class

IP 54, in vertical position.

Mounting position

Vertically upright and horizontal. DCM4016

and 4025 vertically upright.

Ambient temp. at switching device

–25…+70 °C, except: DCM4016,

4025, 1000: –15…+60 °C

Max. medium temperature

The maximum medium temperature at the

pressure sensor must not exceed the

permitted ambient temperature at the

switching device. Temperatures may reach

85°C for short periods). Higher medium

temperatures are possible provided the above

limit values for the switching device are

ensured by suitable measures (e.g. siphon).

Mounting

Directly on the pressure line (pressure

gaugeconnection) or on a flat surface with two

4 mm Ø screws.

Switching pressure

Adjustable from outside with screwdriver.

Switching differential

Not adjustable with DCM and types. Adjustable

from outside with DCMV types. For values see

Product Summary.

For smaller pressure ranges see also VCM, DGM, HCD and DPS sheets.

For additional functions refer page 30 – 32.

Calibration

The DCM series is calibrated for falling pressure. This means that the adjustable switching pressure on

the scale corresponds to the switching point at falling pressure. The reset point is higher by the amount

of the switching differential. (See also page 27, 1. Calibration at lower switching point).
