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.
