Low-Frequency / Low-Level Piezoelectric Charge Accelerometer
Type 4381 piezoelectric charge accelerometer is designed with a side connector and supplied with cable included, for general purpose low-frequency measurements over 0.1 Hz to 4800 Hz.Request Price
Type 4381 is a piezoelectric, DeltaShear®, Unigain® accelerometer with side connector. Type 4381 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
- Low-level, low-frequency measurements
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.
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%.
