PRESSURE

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

2000 housing is specically designed to mount in the same diameter cutout as a

standard Magnehelic

to specic ranges. Pressure connections are inherent to the glass lled 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 eld 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® simplies eld upgrade to digital pressure gage by

reducing install steps

• Tamper proof button conguration to prevent accidental changes to the settings

APPLICATIONS

• Differential pressure across lters

• Fan control

• Static pressures in ducts or buildings
