Dwyer series DM-1000 magnehelic differential pressure gauge 0-0.25''w.c., stainless steel
Introduction 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.
Specification
Working principle 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 w.c. and 2% accuracy down to the very low ranges of 1 in to 0.25
in w.c. 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.
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.
