FEMA DDCM pressure switches are designed for monitoring and controlling differential pressures, flow conditions and filter systems. The double-chamber system measures the pressure difference between two inputs. The switching pressure can be continuously adjusted within the specified ranges (see technical data sheet). These differential pressure switches are also suitable for use in vacuum applications. The switching differential is fixed and cannot be adjusted. The devices feature a robust, seawater-resistant die-cast aluminum housing. The DDCM series is factory-calibrated for falling pressure, meaning the scale value corresponds to the switching point when the pressure decreases.

Features and Benefits:

• Differential pressure switch calibrated for falling pressure
• Wide control range
• Female thread G1/4"
• SIL2 approved according to IEC 61508-2
