Specifications - Installation and Operating Instructions

he Series DPG-100 Digital Pressure Gage has a precise +/- 0.25% full scale

T

ccuracy. The 4 digit digital display will reduce the potential for errors in readings

a

y eliminating parallax error commonly produced with analog gages.

b

The DPG-100 is packaged in a durable extruded aluminum case designed to meet
NEMA 4/4X. The unit is battery powered and has an auto-shut off to conserve bat­tery life. A four button key pad allows easy access to features without the need to

ork through complex menus or difficult key combinations. These features include

w

acklight, peak and valley, auto zero and conversion of the pressure units.

b

eadings may be converted to various engineering units. See reverse page for

R
available units.

DPG Quick Start Button Operation

For complete detailed instructions on the four button operation see the Operation
Chart provided on back.

On/Backlight: Push to turn on; Press again for backlight. Press and
hold for 5 seconds to turn unit off.

Zero: Zeros the display - Push & hold for 2 seconds to zero the display.
If after pressing zero the display does not re-zero, the unit is no longer
meeting specified accuracy and should be sent back to the factory for
calibration. Do not use the zero button when pressure is applied.

Units: Scroll (see next page for Model/Range Chart).

P/V: Peak recorded reading retrieved by initial push of button; push

again retrieves the valley or lowest value recorded.

INSTALLATION

When installing gage always use 1˝ hex at the base of the housing to tighten the
gage to a mating fitting. Do not apply wrench to housing.

MAINTENANCE

A “LOW BAT” descriptor indication will appear on the display when batteries need
to be replaced.

Battery Replacement: Remove the three screws on backplate. Lift backplate off
by hand. Replace batteries per polarity indicators. To reassemble, ensure O-Ring
seats into housing evenly and press until seated completely. Replace screws.

Ranges: 0.5% full scale; ± 1 least sig­nificant digit @ 70°F (21°C) . (Includes
linearity, hysteresis, repeatability).
Pressure Limit: 2x pressure range for
models ≤1000 psi;5000 psi for 3000
psi range;7500 psi for 5000 psi range.
Enclosure Rating: Designed to meet
NEMA 4/4X (IP65).
Temperature Limits: 0 to130°F
(-18 to 55°C).
Thermal Effect: Between 70 to 130°F

*Note: Gages with ceramic sensor are not CE and FM approved.

WARNING: DO NOT pressurize DPG over maximum allowable pressure limits.
Extreme damage can occur if limits are exceeded (see Pressure Limit under
Specifications). An overflow “OFL” designator will flash to acknowledge that the
gage’s pressure range has been exceeded.

PANEL MOUNT OPTION

Drill a 3-1/4˝ (82.55) diameter hole in a panel, locate three mounting holes for a #6
screw 120° apart on a 3-58˝ (92.08) bolt circle.

Battery Life: 2000 hours typi-cal; low
battery indicator.
Auto Shut-Off: Gage: 60 minute auto
shut-off. Auto shut-off may be
disengaged; Backlight: 2 minute auto
shut-off.
Agency Approvals: FM approved to
be intrinsically safe for Class I,
Division I, Groups A,B, C and D, for
ranges 0-15 to0-3000 psi. CE EMC

WARNING: Substitution of components may impair intrinsic safety. Batteries must
be changed in a non-hazardous location only. DO NOT mix batteries from different
manufacturers. DO NOT mix old batteries with new batteries.
