Description

2ch AC Strain Module for the RA3100 Data Acquisition System.

This input module enables stress measurement using strain gauges as well as strain gauge transducers such as load cells, pressure transducers, and torque transducers. The AC bridge method can be used for measurement that is strong against external noise.
