Abstract
A sensor module for a compressor having an electric motor connected to a power supply and a processor disposed within an electrical enclosure of the compressor is provided, with the electrical enclosure being configured to house electrical terminals for connecting the power supply to the electric motor. The sensor module includes a first input connected to a voltage sensor that generates a voltage signal corresponding to a voltage of the power supply and a second input connected to a current sensor that generates a current signal corresponding to a current of the power supply. The processor is connected to the first and second inputs. The processor may calculate a power factor of the compressor, detect an unexpected variation in the power supply, and/or detect a mechanical malfunction of the compressor based on the voltage measurements and the current measurements.
