Series

Differential Pressure Transmitter

DM-2000

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 simplifies calibration over typical turn-potentiometers. An optional

3.5 digit LCD shows process and engineering units. A single push button allows field selection of 4 to

6 engineering units depending on range.
