The Kistler 8694M1 Piezotron® triaxial accelerometer essentially consists of three individual sensor elements mounted in an orthogonal configuration with each containing a quartz-crystal measuring assembly, a seismic mass and an integrated impedance converter. The quartz assembly located between the sensor body and the seismic mass is preloaded by a flexible member. The electrical charge yielded by each quartz crystal meauring element is directly proportional to that portion of the acceleration signal incident on the sensor's mounting surface.

A Piezotron® accelerometer has integrated miniature electronics which provide a low impedance signal at the output. Since the 8694 is a triaxial accelerometer, each sensor axis requires individual excitation power and signal processing. Kistler's 1500 Piezotron® coupler series includes a wide selection of single and multichannel units that include both gain and frequency tailoring.
