Abstract
A process controller is provided and includes at least one optical sensor. The optical sensor includes an optical source is configured to emit an electronic signal toward an object. The process controller further includes a control unit in communication with the at least one optical sensor, wherein the control unit controls a controlled device based on the electronic signal received by the at least one optical sensor. In another form, the optical sensor further includes an optical detector configured to receive the return electronic signal reflected by the object. A system for process control in an elevated radio frequency (RF) environment is also provided and includes a process controller having at least one optical sensor and a control unit in communication with the optical sensor. The optical sensor is disposed within the elevated RF environment and includes an optical detector.
