Abstract
A diagnostic device for use in a process control system receives a sensor signal related to a process variable of a process sensed by a process variable sensor. A signal preprocessor provides a sensor power signal output as a function of a frequency distribution of power in the sensor signal. A process condition is determined based upon the sensor power signal.
