Abstract
A sensor module for a compressor having an electric motor connected to a power supply is provided. The sensor module includes an input that receives current measurements generated by a current sensor based on a current of the power supply. The sensor module also includes a processor. The processor is connected to the input, determines a maximum continuous current for the electric motor, and selectively compares the current measurements with a value equal to the maximum continuous current multiplied by a predetermined value. The maximum continuous current is set based on at least one of a type of refrigerant used by the compressor and actual refrigeration system conditions.
