Product Overview
DM-202 is a Series DM DigiMag® differential pressure transmitter senses the pressure of air and compatible gases and sends a standard 4-20mA output signal. The DM housing is specifically designed to mount in the same diameter cut-out as a standard Magnehelic® gauge. Typical applications include differential pressure across filters, fan control, static pressures in ducts or buildings, room pressurization monitoring.
- ±0.25" water column accuracy
- 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® gauge
- Power requirements of 10-35VDC (2-wire)
- Output signal range from 4-20mA (2-wire)
- Push-button zero and span adjustments
- Screw-type terminals electrical connections
- NEMA 4X (IP66) enclosure rating
