± 0.02 % of AutoRanged spans from ± 1 kPa (0.15 psi) to 14 MPa (2,000 psi)

The Fluke Calibration PPC4E pressure gauge calibrator brings high performance to a wide range of pneumatic pressure calibrations, from the cal lab to production or field calibration environments. Move up to the well-known reliability and precision of Fluke Calibration PPC pressure controller/calibrators and enjoy great value and return on investment.

PPC4E combines the best features, measurement technology, and patented PPC hydraulic pressure controller from our PPC4 family of controller/ calibrators to deliver extremely broad pressure range coverage at a level of performance that addresses your most common calibration workload. Calibrate transmitters, transducers and analog and digital gauges with ease using the color graphical user interface, or automate through remote connection to a PC. PPC4E makes it extremely easy to ensure that you’re getting the performance and uncertainty you need for all of your pressure gauge calibrations. PPC4E’s AutoRange feature instantly sets up multiple parameters to achieve optimum precision, safety, and measurement performance anywhere in its pressure range. Users simply enter the range and tolerance of the unit under test. PPC4E’s measurement uncertainty is then a percentage of a span that is aligned with the UUT range, providing an easy-to-understand test accuracy ratio.

Rangeability of PPC4E models
Models are designated either PPC4E or PPC4EX, indicating either one or two internal reference pressure transducers and defining the minimum AutoRange span that can be selected while still maintaining the calibrator’s best measurement uncertainty. Nominal measurement uncertainty is ± 0.02 % of AutoRanged span for any AutoRange down to:
PPC4E 10 % of controller span
PPC4EX 1 % of controller span
See PPC4E measurement specifications for details. Fluke Calibration provides a complete and reliable product measurement uncertainty specification including all sources and valid for one year.

Realize control precision and low uncertainty over the entire PPC4E range
PPC4E may take the place of two or more pressure controllers. There’s no need for two separate control modules in PPC4E. Control precision better than ± 0.0006 % of the controller’s span, and up to ten times tighter at the low end, allows users to take full advantage of precision in typical dynamic control operation. PPC4Es quartz sensor technology is also superior to that of other controller/calibrators in its class. PPC4E gives you all the range and precision you need with a single interface and a single test port.

Easy-to-use, information-packed user interface
Operation of PPC4E from its local user interface offers you instant optimization of all its important settings and parameters to the range and accuracy of your UUT with a few touches of a button using the AutoRange function. Operators will find common calibration tasks simple to perform without specialized training or experience.

PPC4E supports setting up and running quick tests on the fly and creating and storing test sequences for recall and execution. A “jog" feature allows for the pressure at each target point to be manually adjusted so the UUT reads a cardinal target pressure, a useful feature for analog gauge calibration. When running a test sequence, the PPC4E measured pressure corresponding to each UUT cardinal point is recorded and displayed later for reporting. Uncertainty of the measured or delivered pressure is calculated and displayed continuously by PPC4E. The calculation uses uncertainty components based on PPC4E specifications and the component values can be tailored by the user.

COMPASS® software for automation
PPC4E is ready for integration into a fully automated test system. Rear panel RS-232 and IEEE-488.2 interfaces are included for communication with a remote computer. Remote operation is supported by a complete set of easy-to-use, well documented command strings.

Fluke COMPASS for Pressure calibration software provides an off-the-shelf path to automation, enabling you to realize the benefits of automation without dedicating your engineering resources to create a custom program. COMPASS for Pressure has the power and flexibility to automate nearly any level of testing imaginable, including all aspects of test execution, data acquisition and report generation, whether for a bench top calibration system or a complete, multi-function sensor test stand.

Fluke Calibration also offers integrated, turnkey calibration systems including pressure generation, control and data acquisition hardware in solutions ranging from mobile carts to attractive, small-footprint rack systems.

Specifications

Maximum deviation of the RPT indication from the true value of applied pressure including precision, predicted one year stability limit, temperature effect and calibration uncertainty, combined and expanded (k=2) following the ISO “Guide to the Expression of Uncertainty in Measurement."

1. For AutoRange spans below the Minimum AutoRanged span uncertainty is equal to the value at the Minimum AutoRanged span.
2. Gauge uncertainty is a % of AutoRanged span. For example, an AutoRanged span of 3 500 kPa on model PPC4E 7M would have uncertainty of (0.02% * 3 500 kPa) = 0.35 kPa.
3. Absolute uncertainty is the sum of a % of AutoRanged span and a Constant that accounts for zero drift. For example, an AutoRanged span of 80 kPa on model PPC4EX 100K would have uncertainty of (0.02% * 80 kPa + 0.014 kPa) = 0.03 kPa.

On-board barometer

The on-board barometer is used only to measure changes in atmospheric pressure to provide dynamic compensation of an absolute RPT’s atmospheric pressure offset in gauge measurement mode with PPC4E models other than PPC4E 15k.
