Compressor sensor module
First Claim
1. For a sensor module with a processor disposed within an electrical enclosure of a compressor having an electric motor, said electrical enclosure being configured to house electrical terminals for connecting said electric motor to a power supply at a first operating voltage, a method comprising:
- connecting said sensor module to a transformer for generating a second operating voltage from said power supply, said first operating voltage being higher than said second operating voltage and said processor operating at said second operating voltage;
connecting said electrical terminals to said power supply operating at said first operating voltage;
receiving voltage measurements of said power supply from a voltage sensor connected to said sensor module;
receiving current measurements of said power supply from a current sensor connected to said sensor module;
communicating operating information based on said current and voltage measurements to a control module connected to said sensor module via a communication port of said sensor module.

Abstract
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.
