Abstract: A non-contact capacitance sensor having a base and an array disposed on the base is provided. The array has a first electrode and a second electrode disposed opposite one another so that the array senses a change in capacitance between the first and second electrodes.

Abstract: The present invention relates to a wrap around booster (10), and more specifically, the present invention relates to a wrap around booster (10) for use with a high temperature dishwashing machine (40). The wrap around booster (10) heats the water of the dishwashing machine (40) from approximately 110-140° F. to at least 150° F. in the wash tank (11) and at least 180° F. in the rinse tank (26). This is accomplished by keeping a relatively constant volume of water in the rinse tank (26) containing the wrap around booster (10), which maintains the rinse tank water at least 180° F. The rinse tank water surrounds the wash tank (11). The warmer water in the rinse tank (26) surrounding the wash tank (11) therefore heats the water contained in the wash tank (11) through convection. Therefore, one heating system does the work of two heating systems.
