Type 4382 offers 10–32 UNF storage for output connection which can be fixed on the object through a 10 – 32 UNF threaded steel stud. It's a DeltaShear®, Unigain®, piezoelectric accelerometer with top connector, used as a charge source.

Its sensitivity is indicated in terms of charge per unit acceleration (pC/g). Meanwhile, its design which housing is made of aluminum includes three piezoelectric elements (PZ 23 lead zirconat titanate) and three masses assembled in a triangular configuration around a triangular center post.

This can be applied for vibration testing and analysis, low-level and low-frequency measurement, high sensitivity, and major uses.
