ABSTRACT:
A temperature sensor utilizes a resistive element and a thermocouple. One or more leads of the thermocouple are surrounded (electrically insulated) by a conductor or conductors constituting the connections to the resistive element. The conductors are made of a nonmagnetic material. In one embodiment, the second thermocouple lead is constructed as a hollow pipe which constitutes a protective outer casing for the necessary unit, as well as a connection to the resistive element. Embodiments utilizing a plurality of thermocouples are illustrated, as is a similarly constructed cable for connecting the sensor unit to measuring apparatus.
