Radio telemetry in experimental stress analysis

This report describes in detail, for the potential user, the evaluation and application of an FM/FM radio-telemetry system designed to transmit strain and temperature data from rotating parts. Three resistance-strain-gage transmitters, one thermocouple transmitter, and two receivers were thoroughly checked in the laboratory and evaluated in a number of field measurements. The laboratory investigation showed that strain and temperature data could be accurately transmitted with the telemetry equipment, and several field applications confirmed that the data obtained using the telemetry equipment were in good agreement with theoretical calculations.
