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
