This paper studies the impedance temperature characteristics of the eddy current sensor coils in a wide temperature range under high frequency and proposes a method of eliminating or reducing the influence of the temperature variation on the coil impedance by using multiple wires. The law of temperature change of the impedance of multi-wire whirling sensor coil in large temperature range was studied. Theoretical analysis and calculation show that the multi-wire stranded wire coil can effectively suppress the temperature drift of the coil.
