This report concerns the development of a small radio-telemetry torquemeter package intended to replace a current slip ring driveshaft torque meter system. Included in this report is a package description, a comparative test report and application recommendations. The torquemeter package developed can be used in any driveshaft, vehicle or otherwise, in place of a standard universal joint. Package constituents are a strain gaged universal joint cross and telemetry consisting of a modern FM transmitter and FM receiver. Transmitter power is available in battery form, or an inductive power supply can be built into the transmitter and receiver. The package was installed in series with a slip ring unit to conduct a comparative test utilizing both power supplies. Test results were not influenced by power supply and indicate identical data.
