ABSTRACT:
A temperature sensor includes a first sensor section having first and second conductors connected at their one ends and defining macroscopic current paths directed in different directions with respect to that of a magnetic field and having resistance values such that the magnetic field produces identical changes in resistance therein, a similarly constituted second sensor section having third and fourth conductors connected to the second and first conductors, and heat coupling means for keeping the temperature of the first and second sensor sections uniform. The sensor measures the environmental temperature of the magnetic field from the voltage occurring between the connection point of the first and second conductors and the connection point of the third and fourth conductors when current is supplied to the first and second sensor sections through a current supply point at the connection point of the first and fourth conductors and a current supply point at the connection point of the second and third conductors.
