NEMA 4X (IP66) Case

The DPG1000 Series is a versatile family of industrial
pressure/vacuum gauges. All DPG1000 models feature
a large 13 mm (1⁄2") high digital display in a rugged,
splashproof extruded aluminum case.

A

⁄4-18 NPT 316 stainless steel fitting is standard for the
pressure connection. Media compatibility includes all
liquids and gases compatible with 316 SS.

The DPG1000B Series features a wide operating
temperature range of -20 to 85°C (-4 to 185°F). Many
standard pressure/vacuum ranges (in a choice of
engineering units) with both gauge and absolute references
are available. The series also features ± 2x overpressure,
and 4x burst specifications, and are available with either

0.25% or 0.10% accuracy.

DPG1000AD (AC/DC Powered)

The DPG1000AD is powered
by either 8 to 24 Vac, or 9 to
32 Vdc. No recalibration is
needed, and no jumpers
have to be moved to use
either AC or DC power
within the specified
range.
No polarity needs to
be observed when
connecting a DC
supply. Therefore,
the DPG1000AD can be
used with inexpensive,
unregulated AC or
DC power sources in
applications requiring
continuous pressure display.

DPG1000B (Battery Powered)

The DPG1000B is powered by standard
AA batteries that can operate the gauge for
approximately 2500 hours. All DPG1000B
models include a standard 5 minute auto shut­off feature to conserve battery life. Low-battery
indication is also standard. An optional rubber boot
(DPG1000-RB) is available. Requiring no electrical
connection, the DPG1000B works equally well in
portable or fixed applications.

DPG1000L
(Loop Powered)

All operating power for the DPG1000L gauge is
supplied by the 4 to 20 mA output loop. This
“2-wire” connection lets the DPG1000L operate
as a digital indicating transmitter in any 4 to
20 mA current loop application. Individual, non­interactive controls are available for the zero/span
display and the output loop 4 to 20 mA settings.
Connection to the DPG1000L is made via a
2-conductor cable at the back of the gauge.

A front-accessible TEST pushbutton switches
the display and output loop to a preset level
determined by the setting of a “Test Calibration”
potentiometer. This feature allows easy testing of
the display and process loop with a preset input
signal in place of the actual input. The DPG1000L
also includes “low loop” warning circuitry. This
circuitry indicates on the display when the loop
supply voltage falls below a level that may not be
sufficient to drive a full 20 mA into the loop load
resistance. These 2 proprietary features make the
DPG1000L easier to set up and maintain.
