Radio Telemetry Applied to Tire Vibrations

This paper discusses the industrial radio telemetry system for use in typical automotive engineering measurements. Considerations of transducer type and measurement class (static or dynamic) are discussed in terms of selection of a telemetry system. Telemetry specifications and their interpretations are discussed along with characteristics and limitations of direct/FM and AM/FM systems. As an example application the measurement of inservice tire vibrations with radio telemetry is presented. The example includes selection and calibration of the telemetry system and presentation of typical telemetered tire vibration data.
