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.

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.
