    DDCM Differential pressure switches

    DDCM differential pressure monitors are suitable for monitoring and controlling differential pressures, flow monitoring and automatic control of filter systems.All differential pressure monitors can also be used in the vacuum range.

    Overview

    DDCM Differential pressure switches are suitable for monitoring and controlling differential pressures, flow monitoring and automatic control of filter systems. A double chamber system with stainless steel bellows or Perbunan diaphragm detects the difference between the two applied pressures. The desired switching pressure is continuously adjustable within the ranges listed. All differential pressure monitors can also be used in the vacuum range. The switching differential is not adjustable.It comes with Robust housing made of seawater resistant die cast aluminium GD Al Si 12.Mounting directly on the pressure line or on a flatsurface with two 4 mm Ø screws.Note the connection of pressurized lines:P (+) = high pressureS (–) = low pressure

    Features & Benefits:
    • The DDCM series are calibrated for falling pressure
    • This means that the adjustable pressure on the scale corresponds to the switching point at falling pressure
    • The reset point is higher by the amount of the switching differential
    Certifications:
    • SIL2 according IEC 61508-2
