Abstract: A diagnostic system and method to function-monitor an actuator to affect a process medium stream of a process engineering plant can include an optical microphone allocated to the actuator and a diagnostic electronics. The optical microphone can be configured to measure an acoustic, actuator-specific operating signal, as leakage sound and cavitation sound, based on electromagnetic radiation that is affected by the acoustic, actuator-specific operating signal, and generate an electrical measuring signal based on the measured acoustic, actuator-specific operating signal. The diagnostic electronics can be configured to receive and store, process, and/or transmit the electrical measuring signal.
