Vibration standard for calibrating accelerometers, PiezoStar, measuring range 50 g / 8080A

The Type 8080A accelerometer is Kistler’s most accurate and repeatable low impedance, back-to-back, vibration calibration standard. It features low base strain, long-term and thermal stability and high frequency response. Due to its unique shear design, it offers minimum sensitivity to the shaker lateral rotation (rocking motion). A beryllium mounting base, lapped optically flat, provides optimum coupling between Type 8080A and the test unit. Contained within the housing is a piezoelectric system consisting of a seismic mass preloaded to a PiezoStar element and miniature hybrid electronics. This combination yields a high level, low impedance voltage output signal proportional to the accelerating stimulus.
