The Dwyer DM DigiMag Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4-20mA output signal. The DM housing is specifically designed to mount in the same diameter cutout as a standard Magnehelic gauge (2000 and AT2200). A wide range of models are available factory-calibrated to specific ranges. The polycarbonate molded housing features integral pressure connections. 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.

Applications for the DM DigiMag include

• Differential pressure across filters

• Fan control

• Static pressures in ducts or buildings

• Room pressurization monitoring
