Calibration accelerometer uses shear design

The accelerometer is designed for use as a transfer standard for calibrating accelerometers and is suited to laboratory and field applications.

The accelerometer is Kistler’s most accurate and repeatable low impedance, back-to-back, vibration calibration standard and features low base strain, long-term and thermal stability and high frequency response. Due to its shear design, it offers minimum sensitivity to shaker lateral rotation (rocking motion). A beryllium mounting base, lapped optically flat, provides optimum coupling between Type 8080 and the accelerometer being calibrated.

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.

This PiezoStar based sensing element offers long-term thermal stability from −65C to 120°C. The high rigidity provides a frequency response flat to within ±5 % from 1Hz to 10kHz. Both signal and DC excitation power are connected through a single coaxial cable.
