Series DM-2000
Differential Pressure Transmitter
Same Size as Standard Magnehelic® Differential Pressure Gage

The Dwyer Series DM-2000 Differential Pressure Transmitter
senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM-2000 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.

Pressure connections are inherent to the glass filled plastic molded housing making installation quick and easy. Digital push-button zero and span simplify calibration over typical turn-potentiometers. An optional 3.5 digit LCD shows process and engineering units. A single bush button allows field selection of 4 to 6 engineering units depending on range on LCD models.
