Features

Druck Portable High
Pressure Pneumatic
Calibrators

For over twenty years, GE Druck has led the world in
portable pressure calibrator technology and function. The
DPI 320/325 Series of high pressure pneumatic
calibrators are the latest additions to a comprehensive
range of compact and rugged instruments. This range of
portable calibrators is designed to make testing and
calibration of high pressure instruments and systems
both quick and simple. Two versions are available: the
DPI 320, which is the standard model, and the DPI 325,
which has full documenting capability. These
self-contained portable calibrators from GE Druck provide
unparalleled accuracy and control performance. A built-in
gas cylinder provides source pressures up to 3000 psi
(200 bar), a precision pressure regulator and fine volume
adjuster ensures optimum control, and a digitally
characterized sensor measures pressure to better than

0.025% of FS.

Fast and Convenient Solution for
Pressure Calibration

Field and Workshop Operation

The DPI 320/325 Series pressure calibrators are designed
for use in the workshop, in the plant or out in the field.
The large capacity gas cylinder ensures maximum
productivity between refills. In addition, the calibrators
can be operated directly from an external pressure
source connected to the charging port.

Dual Channel Display

The DPI 320/325 Series are dual channel instruments,
able to display both the input and output values
simultaneously. The calibrators are capable of providing
current and voltage excitation to the unit under test (UUT),
and can measure DC voltage, DC current and ambient
temperature. Electrical terminations are made by
industry standard 4 mm sockets, and the large backlit
display provides a clear readout of the process
parameters.

Application Specific Task Menu

A dedicated task key provides instant access to the task
menu, permitting the calibrator to be configured for
specific applications. For example, the P-I task configures
the calibrator to source pressure and measure current at
24 VDC. Loop-power is also available to allow complete
pressure transmitter calibration. Running the pressure
switch task captures the open and closed switch values
and calculates switch hysteresis. The contact resistance
of the switch under test can also be monitored.

Reduce Process Downtime

The DPI 325 version enables calibration criteria to be
easily entered via the keypad, allowing fast diagnosis of
field instruments and automatic reporting of errors with a
Pass or Fail status. When used in conjunction with Intecal
for Industry (i4i) calibration management software, it will
be possible to download test procedures from a PC to the
DPI 325. The calibrator will prompt the technician during
the calibration routine, and the results will be recordered
electronically, reducing downtime and eliminating human
errors.
