摘要： A temperature probe using a first thermocouple junction at the end of a metal tip for measuring the temperature of an object is also provided with a second thermocouple junction on the metal tip at a predetermined distance from the first thermocouple for detecting heat flow in the tip from the first thermocouple toward the second thermocouple. Electronics responsive to both thermocouples drive a heater which maintains the second thermocouple at substantially the same temperature as the first thermocouple, thereby to eliminate heat loading by the probe on the object being measured. A single adjustable resistance temperature detector electronically connected in series with metal tip is used to calibrate the probe and compensate for errors in the temperature readings of the first and second thermocouples. The resistance temperature detector is made up of a wire located in the handle of the probe and is adjusted by stretching the wire to reduce its diameter and bulk resistance.
