A miniature charge accelerometer with side connector designed for high-level, high-frequency measurements in confined spaces and on delicate structures. The accelerometer is supplied with an integral cable. Type 4374 is a piezoelectric, Planar Shear accelerometer. The integrated side cable terminates with a 10 – 32 UNF connector. Type 4374 is mounted on the object adhesively. USE SCENARIOS • High-level, high-frequency measurements • Measurements in confined spaces • Measurements on delicate structures • Vibration testing and analysis This piezoelectric accelerometer may be treated as a charge source. Its sensitivity is expressed in terms of charge per unit acceleration (pC/g). In the Planar Shear design, the piezoelectric element undergoes shear deformation as in the DeltaShear® design. Two rectangular slices of piezoelectric material are arranged on each side of a rectangular centre post. Two masses are held in position using a high tensile strength clamping ring. The ring prestresses the piezoelectric elements to give a high degree of linearity. The charge is collected between the housing and the clamping ring. The piezoelectric element used in Type 4374 and Type 4734-S is PZ 27. Type 4734-L is PZ 23. The housing material is titanium. The sensitivity given in the calibration chart has been measured at 159.2 Hz and an acceleration of 10 g. For 99.9% confidence level, the accuracy of the factory calibration is ± 2%.
