The temperature change has a great influence on the error of the strain measurement. Especially, the quarter bridge is widely used for large scale strain measurement, because the bridge temperature compensation can not be carried out, and the influence of temperature change is more significant. If the use of halfbridge temperature compensation for each channel, the operation is complex, high cost, low efficiency, it is necessary to analyze the error of quarter bridge when temperature changes. In this paper, by analyzing the heat output principle of ordinary strain gauges and temperature selfcompensating strain gauges for strain measurement, the influence of wires and strain gauges on temperature, then given the error of the whole measurement system under the influence of temperature when using the application of BE series ordinary strain gauges and temperature selfcompensation on multichannel acquisition system. The research solves the problem of error assessment of measurement system caused by temperature change in structural strength test, and determines the minimum value of the measured strain required to meet the 1% measurement error in different temperature range.
