Reed Switches in Commercial Coffee Machines
Commercial coffee, tea, and milk vending machines need to dispense enough milk or water for exactly one cup. This can be accomplished by filling up a secondary reservoir fitted with a float and a reed switch which comes on when the reservoir is filled up to 200 ml. This signal can then be used to trigger other solenoids or pumps which stop the main reservoir output and open the drain valve from the secondary reservoir to dispense the liquid into a cup. Using a narrow and long secondary reservoir ensures that errors in measurement do not exceed 5 ml. Suitable products: MS-324 miniature flat pack sensors, MS-10x PCB mountable sensors, and MS-216 cylindrical sensors. |
