Description
The DigiMag® Series DM by Dwyer is a reliable and compact digital differential pressure transmitter, designed for measuring pressure in air and compatible, non-combustible gases. It provides a standard 4–20 mA output for integration with automation and control systems.
The instrument is engineered to fit the same panel cutout diameter as Magnehelic® gauges, allowing easy replacement or upgrade of existing installations without mechanical modifications.
It is available in a wide range of factory-calibrated models for specific measurement ranges. The polycarbonate enclosure features integrated pressure connections, significantly reducing installation time.
Calibration is performed using digital zero and span push-buttons, while measurement units can be selected directly from the device. The built-in LCD display provides clear, local indication of pressure.
