Industrial Telemetry for Applications in the Automotive Industry

The purpose of this paper will be twofold. The paper will initially describe the basic principals of industrial telemetry and the second part of the paper will discuss some applications within the automotive industry. Industrial telemetry is a technique used to transfer data from rotating and moving equipment where other methods of transmitting the data such as slip-rings or rotary transformers are not practical. The transmission of data is accomplished by a very small, rugged, and lightweight RF transmitter which can be conveniently installed in the rotating and moving equipment.

The more common applications include torque and horsepower on drive shafts of all types and the measurement of stress and temperature on rotary components such as gear teeth and turbine blades. These measurements can be accomplished under a variety of conditions, not only in the laboratory, but in actual field testing.
