PPCH-G™, is a pressure controller/calibrator for gas pressure operation from 1 to 100 MPa (150 to 15 000 psi). As with the rest of DHI’s 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.
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 desired range and taking pressure controller rangeability to a new level. A unique pressure control system and gas
booster accessory provide unlimited, on-demand pressure, very high control resolution and 10:1 pressure control turndown. Five 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-G opens new doors in
automated high gas pressure calibration and test applications.
