Low-Frequency Accelerometer

Type 4382 features a 10 – 32 UNF receptacle for output connection and can be mounted on the object with a 10 – 32 UNF threaded steel stud.

USE SCENARIOS

• General-purpose
• High sensitivity
• Low-level, low-frequency measurement
• Vibration testing and analysis

CHARACTERISTICS

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 center 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.

CALIBRATION

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%.
