OMEGA’s DPG409 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 extremely durable digital
pressure gauge designed to survive
harsh industrial environments. The
large 25 mm (1") display is easy to
read at a distance up to 11 m (35').
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 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 externally supplied dc voltage
source. Each unit is supplied with
configuration software that allows
the user to 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.
