Dwyer Instruments' new Series DM-1200 DigiMag digital differential pressure and air-flow gauges have been designed to be more versatile than analog gauges with their ability to be field-programmed to select pressure, air velocity or flow operations. The DigiMag Digital differential pressure gauges have an added feature for filter applications where a set point can be input. When the filter is dirty, the display will blink alerting the user that the maintenance action needs to occur.
Users can program the Series DM-1200 using the menu key to access four menus that provide access to security level; engineering units; K-factor for use with various Pitot tubes and flow sensors, circular or rectangular duct size for volumetric flow operation; filter set point; peak and valley process readings; digital damping for smoothing erratic process applications; display update to conserve battery life and zero and span field calibration.
The Series DM-1200 DigiMag possesses a full-scale accuracy of 1% on ranges down to 2" w.c. and 2% accuracy down to the low ranges of 1˝ to 0.25˝ w.c. DigiMag gauges include 9-24 VDC line power or solely 9V battery power. If using line power and connecting the 9V battery, the battery will act as a back-up if line power is lost or interrupted.
