PPCH™, is a pressure generator/controller/ calibrator for liquid pressure operation from 1 to 200 MPa (150 to 30 000 psi). As with the rest of the Fluke Calibration PPC family of pressure controllers, the emphasis is on high end performance, minimizing measurement uncertainty and maintaining precise control over a very wide pressure range—in a compact and rugged instrument.

New, individually characterized, quartz reference pressure transducer (Q-RPT) modules increase precision and reduce measurement uncertainty. The AutoRange™ feature supports infinite ranging, automatically optimizing all aspects of operation for the exact range to be explored and taking pressure controller rangeability to a new level.

A unique pressure generation and control system provides unlimited, on-demand pressure, very high control resolution and 10:1 pressure control turndown. Four different control modes are included for maximum versatility.

Open architecture allows reference pressure measurement to be internal to or remote from the controller. If desired, the reference can be located at the test measurement point and independently removed for recalibration.

With all of this, PPCH opens new doors in automated high pressure hydraulic calibration and test applications.
