            Abstract : 
To estimate the misalignment error caused by the horizontal movement of fixed coil in the Joule Balance project, a high precision measuring method based on self-alignment capacitive displacement sensor is proposed to measure the displacement of the Joule Balance in the horizontal direction. Results show that the measurement resolution can reach 1 μm.
