Modal Accelerometer 8640A
Internal of 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 8640A... single-axis accelerometer has an integral 10-32 connector and is designed for easy installation in confined areas. Type 8640A... has a welded titanium housing and is ground iso lated when mounted with the mounting clip or adhesive mount ing adapter. The sensing element design provides outstanding amplitude and phase response over a wide frequency range.
