A Digital Electronic Solution to Piston Telemetry

This paper describes the design, development and operation of a digital electronic piston telemetry system. A feature is the multiplicity of operating modes, including two-way communication. The system has been demonstrated to work with thermocouples and accelerometers embedded in the piston of a very small engine at speeds of over 2000rev/m.

The piston-mounted components can be fitted to a piston as small as 80mm diameter, and the size is reduced with every modification as smaller more powerful electronic components become available. Typical results are quoted in the paper
