In this article we will show you which (unwanted) temperature effects can affect the measurement result when using strain gauges. You will also find practical assistance for how you can minimize these effects or compensate for them entirely. The most important points are summarized together at the end of the article in a checklist.
Temperature changes during a measurement with strain gauges can frequently have undesirable effects on the measurement result. Fortunately a number of options are available – with the "right" choice of a strain gauge, the one that suits the application best, by making use of the effects of a Wheatstone bridge circuit with a half or full bridge circuit, and also with computational methods – to compensate largely for unwanted temperature effects.
