The Dwyer series DM DigiMag® differential pressure transmitter sensed the pressure of the air and compatible gases, it sends a standard 4-20mA output signal. The housing on the DM series is designed to mount in the same diameter cutout as a standard Magnehelic® gauge. It features integral pressure connection, which reduces installation time. Digital push-button zero and span provide easy calibration. A single push-button allows field selection of 4 to 6 engineering units, depending on the range.
