Abstract
A FIBEROPTIC PRESSURE SENSOR IS DESCRIBED, IN WHICH THE SENSOR ELEMENTS ARE PLACED IN THE ROOTS OF VARIOUS GEARS. THIS PERMITS AN ENGINEERING EVALUATION RELATING THE MEASURED PRESSURE AT THE GEARTOOTH-ROOT INTERACTION TO THE PERFORMANCE OF THE GEAR. THE SUBMINIATURE DESIGN OF THE ELECTRONICS PERMITS ATTACHMENT OF THE DETECTOR PACKAGE DIRECTLY ONTO THE ROTATING GEAR. THE DYNAMIC PRESSURE IS CONVERTED TO A FREQUENCY SHIFT OF AN RF TRANSMITTER. THE RF SIGNAL IS PICKED UP BY AN ANTENNA LOCATED INSIDE THE TRANSMISSION HOUSING. DATA RECORDING AND ANALYSIS IS PERFORMED BY A TABLE TOP ELECTRONICS UNIT LOCATED AWAY FROM THE TRANSMISSION GEARS.
