DPI 605 IS -1 to 20 Bar C/W Barometric Option
Precision Portable Pressure Calibrators
The DPI 605 precision pressure calibrator which combines Druck’s
expertise in micromachined integrated strain gauge and vibrating silicon
pressure sensors, microprocessor technology and ergonomic styling, has an
accuracy of 0.025% of reading. It is a portable battery powered instrument
with an electrical measurement and supply capability providing simultaneous
pressure and electrical displays, data storage and an RS 232 interface.
The standard range of the calibrator is -1 to +20 bar gauge but ranges up
to 350 bar are available in the indicator version with integral transducers
and 700 bar using an external transducer.
As an option a very high accuracy vibrating silicon transducer can be
added to the instrument to measure barometric pressure. This enables the
simulation of other absolute pressures by adding this barometric value to
gauge measurements. A further option is a temperature probe for measurement
to 200c
Microprocessor technology is used to compensate the sensors and permits a
wide range of functions to be selected. These include peak readings, switch
testing, data logging, leak testing and results’ analysis.
Results obtained during test and calibration can be stored in the
instrument memory for future analysis which may take place directly on the
display or be transferred to a computer via the RS 232 interface. Linkpak-W
and Intecal-W calibration management software support this feature for fully
automated calibration.
The integral pressure generation and adjustment is carried out by a
hand-pump and volume adjuster with a release valve for venting. Where it is
important that maximum pressure for the device under test is not exceeded, a
safety LIMITS function may be selected to automatically block the pumping
action near the desired set pressure.
The DPI 605 is an ergonomically designed enclosure sealed to IP65 for
field use. All main controls are via a membrane keypad and the L.C.D.
graphics dispaly is mounted behind a tough polycarbonate window. This
versatile display provides a wide range of formats, including a “data
recorder” style for trend indication.
It has protected electrical input and output connectors on the sides to
minimise accidental damage, weighs only 4 kg and comes with a lightweight
carrying case.
The instrument is also available as an indicator only. Indicator versions
have all the features of the calibrator except internal pressure generation
and may have integral transducers for ranges up to 350 bar and external
transducers up to 700 bar.
An intrinsically safe version, the DPI 605 IS, powered by approved cells,
offers all the features of the standard unit except for the electrical
outputs and the backlit display.
