SG1 - Strain Gauge Function Module

Module SG1 is NAI’s latest generation Strain Gauge Measurement Module. This intelligent, four-channel module is used on our Multifunction Embedded I/O Boards and Single Board Computers (SBCs). While there are several methods of measuring mechanical strain, the most common is with a strain gauge. The gauge provides electrical resistance that varies in proportion to the amount of strain in the device. The most widely used gauge is the bonded metallic strain gauge. To measure such small changes in resistance, strain gauges are almost always used in a bridge configuration with a voltage excitation source. The general Wheatstone bridge (conventional, 4-arm bridge) consists of four resistive arms with an excitation voltage, Vexc, that is applied across the bridge.
