Description

PIEZOELECTRIC CHARGE ACCELEROMETER, TOP CONNECTOR, INCL. CABLE Designed for general purpose vibration measurements. Type 4370 is a piezoelectric, DeltaShear®, Unigain® accelerometer with top connector. Type 4370 features 10 – 32 UNF receptacle for output connection and can be mounted on the object by means of a 10 – 32 UNF threaded steel stud. USE SCENARIOS General purpose High sensitivity Low-level, low-frequency measurements CHARACTERISTICS This piezoelectric accelerometer may be treated as a charge source. Its sensitivity is expressed in terms of charge per unit acceleration (pC/g). The DeltaShear design involves three piezoelectric elements and three masses arranged in a triangular configuration around a triangular centre post. 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 is a PZ 23 lead zirconate titanate element. The housing material is stainless steel. CALIBRATIONThe 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%.
