Overview

Quartz reference pressure transducer (Q-RPT) modules

PPCH’s outstanding pressure measurement specifications are made possible by Fluke Calibration’s exclusive quartz reference pressure transducer (Q-RPT) modules.

Q-RPTs measure pressure by measuring the change in the natural oscillating frequency of a quartz crystal with pressure induced stress. To be qualified for use in a Q-RPT module, each transducer is individually evaluated and characterized using automated primary pressure standards. Only transducers exhibiting required levels of linearity, repeatability and stability are selected. A proprietary compensation model, derived from more than 15 years experience with thousands of quartz pressure transducers, is applied to optimize the metrological characteristics needed in a transfer standard.

PPCH can be delivered with a low cost utility sensor for applications in which the high precision and stability of a Q-RPT are not required.
