Ex-DDCM Differential Pressure Switches

Ex-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
Ex-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 a robust housing made of seawater resistant die cast aluminium GD Al Si 12.Mounting is directly on the pressure line or on a flat surface with two 4 mm Ø screws.Note the connection of pressurized lines:P (+) = high pressureS (–) = low pressureFeatures and Benefits:•The Ex-DDCM 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.Certificatios: •SIL2 according IEC 61508-2•IBExU12ATEX1040 according to ATEX 2014/34/EU•IECEx IBE 14.0077
