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