RELATED PRODUCTS

GE Druck manufacture a comprehensive range of
pressure indicators, controllers, calibrators,
transducers and transmitters. .
The range of portable calibrators also covers
temperature and electrical parameters.

and data sheets.

CALIBRATION STANDARDS

Instruments manufactured by GE Druck are
calibrated against precision pressure calibration
equipment which is traceable to International
Standards.

The cost effective DPI 603, which extends the
GE Druck range of rugged portable battery
powered pressure calibrators, has standard
ranges of -1 to +1 bar, 2 bar, 10 bar or 20 bar
gauge with an accuracy of 0.075%.

Designed for use in remote locations where
a.c. power is not available, the DPI 603
enables pressure instrumentation to be
serviced and calibrated.

The instrument features the capability to
generate test pressures with an integral hand­pump up to 20 barg. A volume adjuster
provides fine control of the desired test value
and a venting valve enables pressure release
without disconnection of the device under test.

An optional pressure/vacuum switching facility
can also be provided, which enables the hand­pump to source vacuum down to -850 mbarg.

To facilitate pressure transmitter testing and
calibration, an energising voltage of 24V d.c. is
provided and the ability to monitor the loop
current over the range 0 to 55mA d.c.

For loop verification, the DPI 603 can also
output a single 12mA test value, or provide a
passive sink if required.

The clear LCD display allows readout of
pressure, voltage and current parameters with
the ability to show current or voltage
simultaneously with pressure.
