Dwyer Instruments DM-1102

The DigiMag Series DM-1000 Digital Differential Pressure and Flow Gages monitor the pressure of air and compatible gases just as its famous analog predecessor the Magnehelic Differential Pressure Gage. All models are factory calibrated to specific ranges. The 4-digit LCD can display readings in common English and metric units so conversions are not necessary. The simplified four button operation reduces set up time and simplifies calibration with its digital push button zero and span. The DigiMag Digital Gages are more versatile than analog gages with their ability to be field-programmed to select pressure, air velocity or flow operation depending on model. The DigiMag Digital Gages have an added feature for filter applications where a set point can be input where the display will blink when the filter is dirty, alerting the user that a maintenance action needs to occur. Programming the Series DM-1000 is easy using the menu key to access 4 simplified menus which provide access to, depending on model: 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; view peak and valley process readings; digital damping for smoothing erratic process applications; display update to conserve battery life; zero and span field calibration. The Series DM-1000 DigiMag Digital Differential Pressure and Air Flow Gages possess a full-scale accuracy of 1% on ranges down to 2 in H2O and 2% accuracy down to the very low range of 1 inch to 0.25 in H2O. DigiMag Digital Differential Pressure Gages offer power versatility by working with 9-24 VDC line power or simply 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.
