Triaxial accelerometer 8793A series

crystalpiezoelectricshear

Product summary
Family Type 8793A are quartz triaxial accelerometers designed for high and low temperature applications. Contained within the housing of the accelerometers of Type 8793A are three individual shear sensitive quartz elements oriented to respond only to vibration components in the x, y and z axes. Each sensing element is internally connected to a Piezotron microelectronic circuit that converts the charge signal from the quartz piezoelectric element into a low impedance voltage output signal. The K-Shear sensing elements are hermetically sealed in a stainless steel housing and provide long term stability, a wide operating frequency range along with extremely low sensitivity to thermal transients and transverse acceleration.
