Temperature compensation in eddy-current instruments

Ferrites and plastoferrites are being introduced into many applications like eddy-current instruments and others where temperature compensation is required. The temperature coefficient of ferrites is generally much greater than that of cast alloy materials, therefore the compensation with ferrite in general is more difficult. This paper deals with a theoretical investigation of the problem, gives a proposal for the solution, and reports different performances of the proposed system resulting from the degree of compensation used. Conclusions are given with the figures.
