Pressure Switches & Sensors

EX Differential Pressure Switch

FEMA differential pressure monitors are suitable for monitoring and controlling differential pressures, flow monitoring and automatic control of filter systems.

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. The differential pressure switch (e.g. Ex-DDCM1) monitors differential pressure through the pump. The system shuts down if values fall below an adjustable switching threshold. Pump monitoring does not depend on the static pressure in the system.

Features & Benefits:
  • Suitable for monitoring and controlling differential pressures, flow monitoring and automatic control of filter systems
