Capacitance temperature sensor and temperature measuring device

摘要

A capacitance temperature sensor in which temperature is measured by detecting capacitance of a parallel plate condenser which comprises a dielectric material comprising strontium titanate single crystal in which (a) 30% by weight or less of oxygen- 16 or (b) 30% by weight to 50% by weight of oxygen- 16 is substituted with oxygen- 18 isotope.
