Abstract: The traditional four-pole stress sensors suffer some major drawbacks. The structural symmetry varies in different sensors, and their zero value at the zero point is difficult to be guaranteed. In this paper, a selfcompensation structure and a zeroing circuit are designed to solve these problems. With the self-compensation structure, the environmental variables are automatically compensated. By adopting in-phase series and using the voltage output between the middle contact point of the coils and the potentiometer sliding key, the value of the zero point is easily adjustable. The experimental results indicate that the zeroing circuit makes the adjustment of the zero point value easy. Moreover, the output of the sensor is linearly consistent with the theoretical simulation. Therefore, the uniaxial stress in the ferromagnetic materials can be determined accurately by the self-compensation structure sensor with the zero-value adjusting circuit.
