    摘要： A sensor module for a compressor, having an electric motor operating at a first voltage, the sensor module operating at a second voltage, is provided. The sensor module includes a plurality of inputs connected to a plurality of sensors that generate a plurality of operating signals associated with operating conditions of the compressor. A processor is connected to the plurality of inputs and records multiple operating condition measurements from the plurality of operating signals. A communication port is connected to the processor for communicating said operating condition measurements to a control module that controls the compressor. The processor is disposed within an electrical enclosure of the compressor, the electrical enclosure being configured to house electrical terminals for connecting a power supply to the electric motor. The second voltage is less than said first voltage.

    摘要： A compressor is provided and may include a shell, a compression mechanism, a motor, and a diagnostic system that determines a system condition. The diagnostic system may include a processor and a memory and may predict a severity level of the system condition based on at least one of a sequence of historical-fault events and a combination of the types of the historical-fault events.

    摘要： A compressor monitoring system includes current and voltage monitors, current and voltage averaging modules, a control module, and a switch. The current monitor measures a current drawn by a motor of a compressor. The current averaging module generates first and second average current values based on the current measured by the current monitor. The voltage monitor measures a utility power voltage. The voltage averaging module generates first and second average voltage values based on the voltage measured by the voltage monitor. The control module selectively generates a fault signal when a first ratio is greater than a first predetermined threshold and a second ratio is less than a second predetermined threshold. The first ratio is based on the first and second average current values. The second ratio is based on the first and second average voltage values. The switch deactivates the motor when the fault signal is generated.

    摘要： A compressor assembly includes a shell, a compressor housed within the shell, and a motor drivingly connected to the compressor. In addition, a sensor assembly is provided for monitoring operating parameters of the compressor assembly. Processing circuitry, in communication with the sensor assembly, is operable to process the operating parameters of the compressor assembly according to predefined rules. Furthermore, a terminal assembly is hermetically secured to the shell and is in communication with the sensor assembly. A plug is attached to the terminal assembly outside of the shell and serves to operably connect the processing circuitry with the sensor assembly.

    摘要： A data acquisition system and method includes monitoring a cooling system having a refrigerant compressor, evaporator, and condenser, and employs a number of sensors to monitor various operating parameters of the system. These operating parameters are provided to a computer, which stores predefined operating parameters for a plurality of cooling systems. The computer compares the provided operating parameters of the monitored cooling system with the predefined operating parameters to provide diagnostic results for the monitored cooling system and possible service procedures. If the computer does not recognize the monitored cooling system identifier, a connection is made to a master computer in order look up the predefined operating parameters in a master data base.
