OMEGA’s DPGM409 digital
pressure gauge incorporates
a rugged 316 SS enclosure
designed for washdown and marine
applications with a precision 0.08%
accuracy pressure transducer
with 316L SS wetted parts and
body. The result is an extreamly
durable digital pressure gage
designed to survive harsh industrial
environments. The large 25 mm (1")
display is easy to read at a distance
up to 11 m (36'). Models are
available in Gauge, Sealed Gauge,
Compound Gauge, Absolute,
Vacuum and Barometric pressure
ranges. Standard features include
a highly stable silicon sensor,
selectable MIN/MAX and AVG
readings, Hi and LO alarms and an

NEMA 4X case.

Standard integral
pressure sensor

externally powered user selectable
analog output. An optional wireless
transmitter feature with software
allows the signal to be transmitted
to a remote location such as a PC
for charting and data logging. Power
is from an internal long life battery
(included) or an eternally supplied
dc voltage source. Each unit is
supplied with configuration software
that allows the user connect to a
PC via a standard USB connection
(cable included) and select a
variety of user configurable features
including update rate, units,
and backlight.
