PRESSURE TRANSDUCER WITH QUARTZ CRYSTAL OF SINGLY ROTATED CUT FOR INCREASED PRESSURE AND TEMPERATURE OPERATING RANGE

摘要

A pressure transducer comprises a quartz crystal having an orientation within a range of angles between about -25.degree. and about -45.degree. relative to the Z axis of X, Y and Z crystallographic axes. Such a pressure transducer provides a useful pressure response at pressures and temperatures above those of the operating ranges of pressure transducers using AT-cut or BT-cut quartz crystals.
