摘要:
A device in the process control system includes a sensor input receiving a sensor signal. The sensor signal comprises a process variable signal and a residual sensor signal related to sensor operation. Diagnostic circuitry receives a separated sensor signal and responsively provides a diagnostic output related to the sensor. Sensor signal processing circuitry separates the sensor signal into signal components which are provided to the diagnostic circuitry.
