High Sensitivity Charge Accelerometer Type 4383 is a piezoelectric, DeltaShear®, Unigain® accelerometer with side connector. The accelerometer 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 measurement
- Vibration testing and analysis
Type 4384 may be treated as a charge source, and it's 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 pre-stresses 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%.
