Rotary Telemetry
A miniature transmitter is attached to, or installed within the component under test. This converts the transducer signals - usually strain and/or temperature - into a form which enables non-contact transmission - usually inductive or RF.
A stationary pickup mounted nearby receives this signal and re-transmits it via cable to the system demodulator/decoder for conversion to analogue or digital data. In many systems the pickup incorporates an inductive power supply which provides electrical power to the transmitter. In non-demanding applications the transmitter may be powered by a small power unit.
Measurement tasks for rotary telemetry cover many areas and although the operating principle is simple, transmitter designs are becoming even smaller and more specialised - reflecting the trend in modern engineering. As an example, over 70% of our sales are now custom designs.
