Quartz Pressure / CCL Tool The resonant frequency of a shaped quartz crystal varies with the applied pressure. The frequency variation has to be compensated for changes of crystal temperature, hence both pressure & temperature outputs are available from the gauge. Using the compensated data and a calibration, supplied with the gauge, an accurate and high resolution pressure reading is available over the wide measurement range. One temperature sensor build-in is used for compensating.
