Keywords: wind tunnel balance, strain gauges

A very stiff six-component wind tunnel balance of simple construction was produced with semiconductor strain gauges on the axial-load element and with a temperature sensor installed. Thermocompensation was performed by software, treating the temperature sensor as the seventh balance load component. Calibration of the prototype validated the concept.
