Abstract

The eddy current sensor described below is one of several sensors that is currently being used to monitor the pyrolysis of carbon-carbon materials. It is part of a larger system that is being developed for the closed loop control of the carbon-carbon manufacturing process [1]. The eddy current sensor is being used to monitor changes in the electrical conductivity of the specimen.
