Embodiment 2
[0038] Embodiment 2: The difference from Embodiment 1 lies in the spirit level 4 . figure 2 The middle level 4 is an inductive electronic level. The principle of the inductive electronic level: when the base of the level 4 is tilted due to the inclination of the workpiece to be measured, the voltage of the induction coil will change due to the movement of the internal pendulum. The measurement principle of the capacitive level is that a circular pendulum hangs freely on a thin wire. The pendulum is affected by the gravity of the center of the earth and is 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 4 is affected by the workpiece to be measured, the different distances between the two gaps will produce different capacitances and angle differences. figure 2 The middle level detection device 5 is an MCU. Therefore, when the inductive electronic level is in a non-...
