Title: Precision temperature transducer for measuring the surface temperature of the human and animal skin

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.
