Innovation
The latest measuring and control technology is
incorporated into one compact, functional instrument.
Multiple processors, advanced software and a large area
display are among a host of features that make the
DPI 515 the most flexible controll the market, along with
simplified operation and reduced maintenance.
This is the first controller of its type to offer automatic
control valve compensation, giving dependable
operation over long, sustained periods of use with a
variety of system pressures and volumes. Special
attention has been given to ensure suitability for bench
use, with recessed retractable feet to provide a
comfortable viewing angle, or for 19 in (483 mm) rack
installation using the optional rack mounting kit.
Measuring
GE’s ability to design and manufacture both sensor and
instrument has resulted in a powerful combination of
silicon sensor and digital compensation. Precision of
0.01% FS enables high accuracy calibration over a wide
range. Long term stability and temperature effects have
been significantly improved and re-calibration simplified.
High resolution (typically 1 ppm) measurement is
achieved with high performance, self-calibrating
electronics and a full seven-digit display.
Control
The DPI 515 patented (patent numbers: EP0710905A1,
US315540-101 and UK2295249) digital control sets a
new standard for control performance with fast
response, no overshoot and unsurpassed setpoint
stability, better than 0.001% of span.
At setpoint the controller continues to operate with low
noise, wide bandwidth and the result is an almost
immeasurable pressure ripple and stable pressure
control unique to this method.
The fast control loop automatically compensates for
small leaks and thermal changes within the system.
Significant leaks should be avoided for calibration
applications, so the DPI 515 continuously monitors the
pressurized system, indicating leaks on the unique
‘activity Indicator.
Quality
GE is ISO 9001-approved, with all instruments
manufactured to strict quality control procedures and
calibrated against international traceable reference
standards, such as the National Institute of Standards
and Technology (NIST) and NPL, NVLAP and UKAS.
Certification is available upon request.
Simplicity
The DPI 515 is simple to operate, even for those
unfamiliar with pressure calibration or control. The
intuitive menu-style software allows quick selection of
the required function, ensuring that within minutes,
calibrations can be performed with ease and confidence.
High-Speed Calibrations Can be
Performed With Ease and Confidence.
The DPI 515 offers high productivity and improvements
in accuracy and quality, with faster calibrations on
multiple units or in-line processes. It’s the perfect tool for
high speed automation.
Installation
The DPI 515 is designed for 19 in (483 mm) rack systems
using an optional rack mounting kit. For benchtop use,
retractable and recessed feet are fitted as standard,
providing a comfortable viewing angle for the operator.

Sensing
Functions
The following pressure measurement and control
functions can be readily selected from the DPI 515 user
menu:
Dual Range
This option extends both the measuring and control
accuracy of the DPI 515. For this feature the unit is
equipped with a second pressure sensor and a control
manifold is fitted. Uniquely, both ranges are fully
independent, providing control stability based on each
individual FS range. Any two pressure ranges may be
selected. Each range is mechanically independent, with
its own dedicated input and output pressure port
connections, and can be selected either manually or
automatically.
Barometric Reference
A high-precision barometric sensor option can be
installed, which enables gauge pressure ranges to be
converted into absolute pressure values. Precision is
determined by the addition of the barometric reference
precision to that of the pressure range being used.
This option increases the versatility of the pressure
controller, allowing it to perform both gauge and
absolute pressure control/calibration with the same
instrument.
Selecting gauge pressure ranges and using the
barometric reference for absolute pressures ensures
easy zeroing by eliminating the need to apply a vacuum
reference.
Pressure Switch Testing
This function permits automatic and accurate calibration
of pressure switches for opening and closing pressure
values, displaying all associated data, including
hysteresis.
Leak Testing
This function automatically measures leak rates in the
desired units/minute. Once the control system achieves
the required pressure, the controller is isolated, leaving
the measurement software to record any system leaks
over the specified time period.
Test Program
For those who perform regular calibration routines or
process procedures, a facility is included to write and
save up to sixteen test programs. This saves time and
reduces procedural errors.
Span Divider
For quick calibration, each soft key is defined as equal
divisions of a specified pressure span; alternatively, the
soft keys can be set quickly to 10% points.
Preset
For quick calibration, each soft key can be defined as an
individual pressure setpoint value.
Control Rate
The response of the pressure controller is adjustable for
fast, no overshoot and variable. This allows user
selection according to the speed and sensitivity of the
application, for example, “no overshoot” for a valid
hysteresis calibration of dial gauges.
Pressure Units
Twenty-four pressure units are supplied as standard, the
six most popular of these may be set up for quick
selection by the soft function keys.
Aeronautical Units
Full control is available in aeronautical units, altitude in
feet/meters, airspeed in knots, km/hr, Mach and rate of
climb in ft/min and m/min.
Multi-language
The instrument display can be selected to read in
English, French, German, Italian, Portuguese or Spanish,
according to the user preference.
Jog
The setpoint can be moved in small incremental steps
using the rotary control, for example, to determine exact
cardinal points on dial gauges.

Calibration Management
Communication
RS232 and IEEE 488 are standard in the DPI 515, allowing
easy remote control and configuration for integrated
computer driven systems. The popular Standard
Commands for Programmable Instruments (SCPI)
protocol is used to provide standardization with other
instruments. In addition, DPI 500, DPI 510, DPI 520 and
Ruska 7000 Series emulation is available, as well as
Labview®drivers. Example programs for Labview, C++
and VBasic are available at www.DPI515.com.
Software
GE Intecal is a Windows®-based calibration
management software designed for the support of both
laboratory and field-based calibrations. The extensive
management and analysis features included can
interface with many popular GE instruments such as the
DPI 510, DPI 515,
DPI 520, DPI 605, DPI 610 and MCX to offer a complete
and quality assured solution to calibration management.
Connections
All pneumatic and electrical connections are situated on
the rear panel of the instrument for neat and easy
installation.
Head Correction
The pressure change due to vertical heights between the
unit under test and the DPI 515 can be simply
compensated.
Zeroing
Verification of the instrument zero is made simple by the
provision of two methods: manual zero and timed
auto- zero. For manual zeroing, any pressure zero offset
can be corrected by a key press. For timed auto-zeroing,
the instrument may be programmed to zero itself
automatically at a desired time interval.
Logic Input and Outputs
The input allows direct connection of pressure switch
contacts for pressure switch testing, while the two
outputs can be used to control external devices
according to instrument state or remote computer
command.
Filtering
Digital filtering can be selected if required, which
simplifies the reading of fluctuating pressures.
Instrument Status
The calibration and maintenance history of the DPI 515,
along with its configuration, are stored within the
instrument. The calibration history is automatically
updated each time a calibration is carried out. This
ensures information remains permanently with the
instrument, to satisfy quality assurance requirements.
Operating Limits
The controlled pressure range can be restricted to
protect the device under test from either over- or
under-pressure. Alternatively, alarm limits can be set to
provide an audible warning.
Sensor Calibration Module
Optional input card supplies 10V regulated or 24V
unregulated sensor excitation. This reads in mV, mA or
volt output from the pressure sensor under test. It
provides full closed loop calibration on pressure sensors.
