Sensor has an active electrode, safety electrode placed round the active electrode, and screening electrode that is placed round the safety one. All the electrodes are placed in one plane. The active electrode is arranged as a rectangle with sides a and b, where b>a, at that the side b is directed along the long axis of the controlled cylindrical surface. Radial beats are determined as difference between the value of the largest and smallest distances in one complete turn of the shaft. |
