An error estimation technique for joint measurement of magnetic permeability, specific electric resistance and temperatures of a ferromagnetic product via a contact resistorinductive method
Error calculation for a contact working converter (CWC) realizing a resistor-inductive method with the help of a developed parameter measurement error calculation technique for a ferromagnetic product is made, the parameters of δμrt / μrt, δρt/ ρt and δt/t measured. Temperature dependences of relative product-parameters measurement errors are obtained.
