Abstract:
An active temperature differential compensation for strain gage based sensors. An array of temperature sensors can be placed at the gage locations to measure the difference in temperature that induces strain on the strain gages. The output of the temperature sensor network can be placed in series with the strain gage network to directly compensate the induced voltage caused by the temperature gradient and/or employed as the input of a mathematical algorithm that can compensate the output from the strain gage bridge to dynamically correct unwanted thermally induced strain in the strain gages.
