DMG DIFFERENTIAL PRESSURE GAUGE
PRINT E-MAIL BOOKMARK  

The DMG pressure gauge takes advantage of piezoresistive technology to monitor, alarm and/or control critical room to room differential pressures. The same instrument monitors either positive or negative room pressures.

These gauges come with both 4-20mA current output as well as 0-10V voltage output. A 3.5” Red LED display shows the current reading. A red alarm light warns the user in case of excursion. Relays have been provided so as to connect an external alarm buzzer to the device.

DMG gauges allow for configuration of the alarm settings from the device itself. A password protects the settings of the device. Other parameters that can be configured include changing the resolution of the LED display (0.1Pa or 1 Pa), Damping factor and zero adjustment.

A robust die cast metal enclosure houses the electronics. Multiple power options are available at the time of purchase that include 230VAC, 24VDC or 24VAC.
