SYSTEM AND METHOD FOR DETECTING TRANSDUCER FAILURE IN REFRIGERANT SYSTEMS

摘要

There is provided a refrigerant system. First and second transducers are positioned within the refrigerant system to measure respective operational characteristics. There is a timer that determines that a shutdown has occurred for a specified period of time; and a comparator that compares an output of the first transducer to an output of the second transducer after that specified time and determines whether the outputs of the first and second transducers are within a tolerance band of each other. If the readings are not within tolerance band, then the transducer failure is detected and a warning/alarm requiring operator attention is issued.
