主权项

1. A system for process control, the system comprising:
a process controller comprising:
a plurality of process inputs;a plurality of communication ports;at least one optical sensor integrated in the process controller, wherein data of the optical sensor is resident within the process controller; anda control unit in communication with the plurality of communication ports and the at least one optical sensor, wherein the at least one optical sensor includes an optical source that emits light toward an object, and the control unit of the process controller interprets a return light profile reflected by the object to determine a temperature of the object, and controls a controlled device through the plurality of communication ports accordingly.
