SCH-Ex-DDCM Differential Pressure SensorBrand: KOBOLD Instruments, Inc.
The SCH-DDCM differential pressure monitors are suitable for monitoring and controlling differential pressures, flow monitoring and automatic checking of filter plants. A double chamber system with stainless steel bellows resp.
NBR diaphragm accurately detects the difference between the two applied pressures.
The differential pressure to be monitored is infinitely adjustable within the ranges mentioned in the summary of models.
The settings relate to the lower switching point (in the case of falling differential pressure); the upper switching point (in the case of rising differential pressure) is the value of the switching differential higher.
All differential pressure control switches can also be used in the negative pressure area. Every pressure switch has two pressure connections.
