In this paper, the structure and the working principle of an existing linear potentiometer sensor are introduced; furthermore, the structure and circuit connection method of a new linear bipotentiometer sensor is proposed. (e sensitivity, step error, and load characteristics of the existing potentiometer sensor and the linear bipotentiometer sensor are both studied and compared. (e simulation results of their static characteristics show that the sensitivity of the linear bipotentiometer sensor is increased, the relative load error is greatly reduced, and the linearity is improved. Meanwhile, the measurement accuracy of the linear bipotentiometer sensor is effectively improved.
