    Abstract

    Thermal output from two different strain gage types was analyzed over a temperature range from 20–500°C. The influence of applied loads was also examined. The strain gages were attached to the specimens in three different configurations. Thermal output was efficiently compensated for using a quarter-bridge configuration. Relative large errors were found using half-bridge configurations. The obtained thermal output values, with and without application of load, are discussed.
