Dwyer DM Series Digimag® Differential Pressure Transmitters w/ LCD Display

The Dwyer series DM DigiMag® differential pressure transmitter sensed the pressure of the air and compatible gases, it sends a standard 4-20mA output signal. The housing on the DM series is designed to mount in the same diameter cutout as a standard Magnehelic® gauge. It features integral pressure connection, which reduces installation time. Digital push-button zero and span provide easy calibration. A single push-button allows field selection of 4 to 6 engineering units, depending on the range.

Features

• Reduces installation time with zero and span controls that provide quick & easy calibration
• Immediate corrective action can be taken on local alerts with the easy to read LCD display
• Reduces upgrade installation costs and simplifies upgrade from a Magnehelic® gauge due to both have the same diameter cutout

Applications

• Filter monitoring
• Fan control
• Static pressure in ducts and buildings
• Room pressure monitoring
