Abstract

A temperature probe is formed by enclosing a thermistor in a sensor sheath one of whose ends is closed and in engagement with the thermistor, and by biasing the thermistor into engagement with the inner surface of the sheath. The biasing is accomplished by coiling the transistor wires and using them as a compression spring. A closed air space is formed within the sheath by closing its other end with the end of a coaxial cable and overmolding an outer housing.
