Ex-DCM / Ex-DNM pressure switches and pressure monitors for overpressure

These universal pressure switches and pressure monitors can be used in general mechanical engineering, in the printing machinery industry and in pneumatic and hydraulic applications.

Ex-DCM / Ex-DNM pressure switches and pressure monitors for overpressure feature a robust housing made of seawater-resistant die-cast aluminium GD Al Si 12. For Ex-DCM types, the switching differential is not adjustable. For Ex-DNM types, the switching differential is adjustable.

Features and benefits

• The Ex-DCM / Ex-DNM series is calibrated for falling pressure.
• The adjustable switching pressure shown on the scale corresponds to the switching point at falling pressure.
• The reset point is higher by the amount of the switching differential.
• Suitable for non-aggressive liquids and gases in industrial applications.
