Series DM DigiMag® Differential Pressure Transmitter

Same Size as Standard Magnehelic® Differential Pressure Gage

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 are available factory calibrated to specific ranges. The polycarbonate molded 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.

Product Applications

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

Reduced installation time through zero and span controls that provides quick andeasy 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 LCDdisplay
Reduces upgrade installation costs and simplifies field upgrade from a Magnehelic®gage, as both use the same diameter cutout
