Dwyer Series DM-2000 Differential Pressure Transmitter

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.
