Description
Dwyer SERIES DM DIGIMAG® DIFFERENTIAL PRESSURE TRANSMITTER
Same Size as Standard Magnehelic® Differential Pressure Gage
The Series DM DigiMag® Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The DM 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. The polycarbonate molded housing features integral pressure connections, which reduces installation time. Digital push-button zero and span simplify calibration over typical turn-potentiometers. A single push-button allows field selection of 4 to 6 engineering units, depending on the range.
Features:
- Reduced installation time through zero and span controls that provides quick and easy calibration
- Fast and easy setup and calibration with push-button zero and span controls
- Immediate corrective action can be taken by local alerts via the easy-to-read LCD display
- Reduces upgrade installation costs and simplifies field upgrade from a Magnehelic® gage, as both use the same diameter cutout
Applications:
- Differential pressure across filters
- Fan control
- Static pressures in ducts or buildings
- Room pressurization monitoring
