FEMA / Honeywell differential pressure monitors Ex-DDCM are suitable for monitoring and controlling differential pressures, flow monitoring and automatic control of filter systems. A double chamber system with stainless steel bellows of Perbunan diaphragm detects the difference between the two applied pressures.
