4370 – Piezo Charge Accelerometer

High sensitivity accelerometer with top connector

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.

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.
