Temperature and humidity detecting element

Abstract

Abstract PURPOSE:To detect temperature and humidity accurately even when measurements are taken with a detector held in a hand by shielding the detector from radiant heat from the hand wherein the detector is held. CONSTITUTION:A temperature and humidity detector consists of a temperature detecting element 1, a humidity detecting element 2, a cover 3 which protects the elements, a holding part 4, and a shield plate 5. Then, the temperature detecting element 1 is a glass-sealed thermistor which has a diameter of about 3mm and a length of about 6mm and the humidity detecting element 2 is a ceramic sensor of ZnCr2O4-LiZnVO4 which have a diameter of about 6mm and a thickness of about 0.3mm. The shield plate 5, on the other hand, is made of a disk of vinyl chloride having a diameter of about 30mm. Thus, the shield plate 5 is provided in this constitution to measure the ambient temperature accurately without any influence of radiant heat from the hand.
