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 havingan orientation within a range of angles between about -25° andabout -45° relative to the Z axis of X, Y and Zcrystallographic axes. Such a pressure transducer provides auseful pressure response at pressures and temperatures abovethose of the operating ranges of pressure transducers usingAT-cut or BT-cut quartz crystals.
