ABSTRACT:
The present invention is an apparatus for monitoring the running time and cycle time of electric motors. The apparatus diagnoses fuel consumption and burner functionality in heating plants by measuring elapsed motor running time. Alternatively, the apparatus diagnoses the running and cycle time of refrigeration and air conditioning motors for the purpose of measuring efficiency and predicting failures. The Apparatus has three major components: an inductive sensor device mechanically attached to the motor; a microprocessor device connected by cable to the inductive sensor device that records time and sensor device data and retransmits it; and the central monitoring device. The microprocessor device is connected by telephone to the central monitoring device. Using historical data of fuel deliveries and consumption and the sensor-supplied running time information, the central monitoring device will predict when the fuel tank needs refilling. The data can be used to indicate a failure has occurred. In addition, the central monitoring device is able to monitor a plurality of sensor devices. This data can be used by a fuel company to schedule and optimize fuel deliveries. When used in refrigeration and air conditioning applications, the apparatus monitors the time the compressor motor is running and the time it is idle. This ratio provides the efficiency of the system and advance notice of potential failures and possible refrigerant loss.
