DDCM Differential Pressure Switche

FEMA DDCM differential pressure Switche monitors are suitable for monitoring and controlling differential pressures.

FEMA differential pressure monitors 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 mentioned in the product summary. All differential pressure monitors can also be used in the vacuum range. The switching differential is not adjustable.

The maximum medium temperature at the pressure sensor must not exceed the permitted ambient temperature at the switching device. Temperatures may reach 85C 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). 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.
