A Technique for Increasing the Linear Range of a Magnetoresistor Displacement Transducer

A technique for increasing the linear range of a magnetoresistor displacement transducer by means of shaped pole pieces is developed. The method of determining the required profiles is discussed and observations on the machining of the pole pieces are made. Practical results given in the paper show a sevenfold increase in the linear range. The technique described may have applications in other fields.
