Abstract
A system has a first temperature sensor located at a first location. A second temperature sensor is located at a second location. A control is configured to determine a difference between voltages indicated of a temperature sensed by each of the first and second sensors. A method is also disclosed.
Claims10
A system comprising:
- a first temperature sensor located at a first location and a second temperature sensor located at a second location;
- and
- a control configured to determine a difference between voltages indicative of temperatures sensed by each of said first and second temperature sensors and associate the determined difference with a temperature difference between the first and second location;
- each of said first and second temperature sensors being configured to communicate to a measurement system through a pair of wires, said measurement system configured to communicate to said control;
- said pair of wires from each of said first and second temperature sensors extending directly to said measurement system;
- wherein said temperature difference is utilized to monitor the health of a component in an associated system, the component being at least one valve.
