KBC-220 explosion-proof tilt switch, coal stacking blockage switch KBC-220 explosion-proof tilt switch, coal stacking blockage switch KBC-220 explosion-proof tilt switch, coal stacking blockage switch conveyor belt deviation detector; Material shortage probe of the car overturning machine; Used for detecting material shortage or absence in belts and vibrating feeders. The tilt switch of the vertical suspension is subjected to external force. When deviating from the vertical position by more than 20 degrees, the internal contacts of the switch act and the normally closed contacts open. After the external force is withdrawn, the tilt switch returns to the vertical state and the contacts close again. Using the New Year's greetings of the opening and closing of the internal contacts of the KBC-220 explosion-proof inclined blockage switch to determine the working condition of the equipment, in order to take timely measures and protect the equipment.
