Specications - Installation and Operating Instructions

Bulletin A-34A

The Series DPG-200 Digital Pressure Gage has a precise ±0.25% full scale
accuracy. The 4 digit digital display will reduce the potential for errors in readings by
eliminating parallax error commonly produced with analog gages. The DPG-200 is
packaged in a durable extruded aluminum case designed to meet NEMA 4X (IP66).
The unit is powered by 12 to 24 VDC/VAC and contains two alarm set points along
with a 4 to 20 mA process output. A four-button keypad allows easy access to features.
These features include backlight, peak and valley, auto zero and conversion of the
pressure units.

INSTALLATION

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

• Top line shows units.

• Bottom line shows pressure.

• If pressure is 1% FS below range of instrument the pressure value will alternate UFL on a 1 second interval.

• If pressure is 1% FS above range of instrument the pressure value will alternate with OFL on a 1 second interval.

• Factory set to PSI.

See menu page.

Zeros display if within ±4% F.S. of zero.

See units chart below.

See peak/valley.

PEAK

• Highest pressure since peak and valley was reset.

• Zero button resets both peak and valley to the current pressure.

VALLEY

• Lowest pressure since peak and valley was reset.

• Zero button resets both peak and valley to the current pressure.
