Digimag® Differential Pressure Transmitter-Series DM 005


The Series DM DigiMag® Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic® gage. A wide range of models is available factory calibrated to specific ranges. The polycarbonate moulded housing features integral pressure connections, which reduces installation time. Digital push-button zero and span simplify calibration over typical turn-potentiometers. A single push-button allows field selection of 4 to 6 engineering units, depending on the range.


  • Reduced installation time through zero and span controls that provide quick and easy calibration
  • Fast and easy setup and calibration with push-button zero and span controls
  • Immediate corrective action can be taken by local alerts via the easy-to-read LCD display
  • Reduces upgrade installation costs and simplifies field upgrade from a Magnehelic® gage, as both use the same diameter cutout


  • Differential pressure across filters
  • Fan control
  • Static pressures in ducts or buildings
  • Room pressurization monitoring
