Description

2ch Acceleration Module for the RA3100 Data Acquisition System.

This module can measure acceleration, speed, and displacement of mechanical vibration using a piezoelectric acceleration transducer (built-in amplifier, charge output type). The periodicity of impact vibration caused by bearing flaws can be observed using RMS conversion and then envelope processing function.
