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.

FEATURES/BENEFITS
• Zero and span controls provide easy calibration checks and shorter installation time to get
device running and monitoring
• Quick response to pressure changes means no delay in signaling and alerting to critical
situations
• Easy to read LCD display provides immediate local alerts allowing corrective action to be taken
quicker to eliminate the problem from becoming widespread
• Same size as Magnehelic simplifies field upgrade to digital pressure gage by reducing install
steps
