Thermal excitation probe fabricating method for use in e.g. transport industry, involves thermally treating carbon substrate fabricated at specific temperature, where temperature is greater than usage temperature of probe

摘要

The method involves providing a Papyex(RTM: Le Carbone-Lorraine) carbon substrate of less thickness. The substrate is fabricated in a manner to form a continuous resistive track (10) of length L in the substrate. The substrate fabricated at a temperature (T1) is thermally treated, where the temperature (T1) is greater than usage temperature (Tu) of the probe. A plain layer is deposited on the substrate at deposition temperature (TD) from a covering layer in electrically insulating ceramic material to the temperature (Tu). An independent claim is also included for a thermal excitation probe.
