ABSTRACT:
A temperature sensor is mounted on the inside surface of a stationary race around which a rotatable race rotates. Electric signals from the temperature sensor are converted into acoustic signals. Without the use of any hard wires, the acoustic signals are received by an acoustic-electric transducer mounted on the outside surface of the bearing housing. These electric signals from the acoustic-electric transducer are frequency demodulated and converted into signals which indicate on a display panel the temperatures within the bearing.
