ABSTRACT:
An apparatus measures temperature of a reciprocating piston and comprises one or more thermocouples of which one end is inserted to a predetermined point of the piston and generates a potential difference according to temperature of the predetermined point. A telemetry unit is mounted on a big end of a connecting rod, computes the piston temperature on the basis of the potential difference, and wirelessly transmits the piston temperature signal.
