Kistler Model 8694M1 Piezotron® Miniature Triaxial Accelerometer
The
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.
• Low impedance voltage mode
• Small size and light weight, less than 2.5 grams
• Quartz sensing element
• Conforming to CE
