Modal Triaxial Accelerometer 8688A
Internal to the PiezoBeam accelerometer is a unique sensing element consisting of a ceramic beam supported by a center post that, when bending occurs as a result of being subjected to vibration, the cantilevered beam element yields an electrical charge. The charge signal is converted by the internal low noise charge amplifier to a proportional high level voltage signal at an output impedance of less than 500 ohms. Patented methods are used to thermally compensate the sensing element. Type 8688A... is a miniature and lightweight triaxial accelerometer that reduces mass loading on thin-walled structures important to multi-channel modal applications or general vibration measurements.
