DM Digimag – Differential pressure transmitter for low ranges with display
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.
