Background
The rotation-resistant level meter is also called as a rotation-resistant level meter or a rotation-resistant level switch, a rotation-resistant level switch and the like, and the functions are different according to different specific purposes. The rotation-resisting material level switch is formed by driving a detection blade to rotate at a low speed after an alternating-current micro-motor is adopted for speed reduction. When the material level of the material to be detected rises to block the rotation of the blade, the main shaft of the detection mechanism generates rotary displacement. This displacement first causes a microswitch to be actuated, signaling the presence of material. Then another microswitch is acted to cut off the power supply of the micromotor to stop rotating. This condition will remain as long as the level of material in the bin is constant. When the material level drops and the detection blade loses the blockage, the detection mechanism is restored to the original state by the spring tension. The micro switch of the micro motor power supply is controlled to act, so that the motor is electrified and rotated. Then another microswitch action signals that this condition will remain as long as there is no material blocking the rotation of the sensing blade.
