Abstract
A pressure status meter acts as an early warning/control device for an air conditioning system used in an automotive, industrial, or heavy equipment environment. The status meter measures the pressure at the condenser side of the air conditioning system and converts the measured pressure into a digital signal. If the signal crosses a predetermined threshold, the meter indicates a "caution" condition or a "shutdown" condition, depending on the severity of the high pressure condition. The device may also include a shutdown circuit that shuts down the air conditioning system if a shutdown condition is detected, preventing high pressure damage and potential freon leaks.
