The principle of electronic level

There are two principles of electronic level: inductive and capacitive. According to different measurement directions, it can also be divided into one-dimensional and two-dimensional electronic levels Inductive principle: When the base of the level is tilted due to the inclination of the workpiece to be measured, the voltage change of the induction coil is caused by the movement of the internal pendulum. The measurement principle of a capacitive level is that a circular pendulum is freely suspended on a thin line, and the pendulum is affected by the gravity of the earth and suspended in a frictionless state. Both sides of the pendulum are equipped with electrodes and the capacitance is equal when the gap is the same. If the level is affected by the workpiece to be measured, the capacitance will be different when the distance between the two gaps changes, resulting in a difference in angle.
