Abstract
A transducer for measuring the surface temperature of the human and of animal skin with a resolution of 0,02 K (0.04.degree.F), a calibration accuracy to within 0,1 K (0,2.degree.F) absolute and a response time within 2 ms has been developed. The transducer includes a tube transparent to thermal radiation and open at both ends. A temperature sensing element is suspended across one end for placement adjacent to the skin.
Claims3
An apparatus for measuring surface temperature, comprising:
- a temperature sensing means;
- and
- an enclosure for placement adjacent to said surface, the temperature sensing means being disposed in the enclosure, said enclosure being transparent to thermal radiation but preventing convective air flow in the immediate environment of said sensing means, inside of the enclosure, when said sensing means in the enclosure has disposition adjacent to said surface.
Dependencies are inferred from the claim text.
