摘要:
A humidity detecting resistor porcelain element, with at least one portion of an electrode being made of a resistance heating unit and the electrode serving for the resistance heating unit and humidity detecting element, and a humidity detecting apparatus using the humidity detecting resistor porcelain element. The heating and cleaning operations of the humidity detecting resistor porcelain can be uniformly and efficiently performed, thus ensuring the stable humidity detection. Also, the circuit construction of the humidity detecting apparatus can be simplified. They can be provided for use in the detecting and controlling operations of the various humidities.
