Because electromagnetic balance sensor is affected by non objection parameters in applications, such as temperature, the output of it can not reflect objection parameter precisely. The method compensating electromagnetic balance sensor based on hardware and neural network is put forward. Artificial neural network has the ability to approximate any nonlinear function at arbitrary precision. This paper utilizes BP arithmetic to rectify data of the sensor according to BP network's nonlinear mapping ability. It is proved by theoretic analysis and simulation results that this method is feasible and validity. Therefore, this method is of great practical significance for the design and application of electromagnetic balance system.
