Senses The Pressure of Air and Compatible Gases, This Differential Pressure Transmitter Features a Pressure Range of 3 inWC and Has a 4 to 20 mA output. Fast and Easy to Set up, This Transmitter is Suitable for Fan Control, Static Pressures in ducts or buildings, room Pressurization Monitoring, and Differential Pressure Across Filters.

Dwyer DM-008 Offers

Specifically Designed to Mount in a standard Magnehelic® Gauge cutout, this pressure transmitter features a polycarbonate molded housing with integral pressure connections, reducing installation time. In addition, the digital push-button zero and span simplify calibration over typical turn-potentiometers, and a single push-button allows field selection of multiple engineering units.


  • Reduced installation time through zero and span controls that provides 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® Gauge, as both use the same diameter cutout


  • Differential Pressure Across Filters
  • Fan Control
  • Static Pressures in Ducts or Buildings
  • Room Pressurization Monitoring
