Series DM-2000 Differential Pressure Transmitter
Quick Response, Easy Calibration Checks
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 push button allows field selection of 4 to 6 engineering units depending on range.
- Filter monitoring
- Fan pressure indication
- Static pressures in ducts or buildings
- Bi-direction ranges ideal for sensing fluctuating building pressure
