Key Features & Specifications

Type 4371 is a piezoelectric, DeltaShear, Unigain accelerometer with side connector. Type 4371 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.


  • General purpose
  • High sensitivity
  • High frequency
  • Vibration testing


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 titanium.
