Method of measuring temperature of electrical conductors - has electrode forming condenser with capacitance compared to calibration graph

摘要

The temperature T is measured a perovskite which is provided, on each of two opposite main surfaces, with an electrode to form a condenser (I). The capacity C is measured and, with the aid of a previously-plotted calibration graph C = f(T), the temperature T is determined. The improvement is that there is used, as perovskite, a substrate, produced from a material, as support for an electrical conductor, the temperature of which is to be determined, is so applied, as first electrode of, on the support substrate, that a good thermal contact exists between the first electrode and the substrate.
