Dwyer - DM Series - DP transmitter

DM

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.
