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
