Summary: | A system is provided for determining the presence, or absence of a component on the end of a vacuum pickup device. A monitor having a transparent body portion and plural air flow passageways is provided. An indicator is provided for each vacuum pickup device and contained within the air flow passageway intermediate a vacuum source and the vacuum pickup device. The position of the indicators within the flow passage is dependent upon the presence, or absence of a component on the end of the vacuum pickup device. With a component present on the pickup device, air flow through the passageway, due to the application of the vacuum source, is minimal and the indicator will be biased in a first direction. However, when a component is absent the pickup device, substantial air flow occurs through the passageway, thereby biasing the indicator in a second direction. In this manner, an operator can visually inspect the monitor of the present invention to determine if each vacuum pickup device has a component affixed thereto. |
