Abstract:
A resistance thermometer probe comprisinga temperature sensor; a housing around said temperature sensor; said housing having 1) a temperature sensing tip for placement of said temperature sensor and 2) a stem to enable said temperature sensing tip to be maintained at a predetermined position for making temperature measurements; said stem being generally cylindrical in shape and said temperature sensing tip being an extension of the stem but is reduced in both diameter and wall thickness to minimize thermal capacity and to maximize heat conduction; electrically conductive wire-leads for connecting said temperature sensor to an ohmmeter; granular particles in said housing to provide mechanical support to said temperature sensor and to reduce heat loss by convection; absorption means inside said housing to capture gases, moisture and volatile organic materials; and sealing means for sealing said housing thereby assuring that said temperature sensor is protected from contimination.
