What is a sensor failure?
A fail-stop failure means that the sensor has stopped responding. A non-fail-stop failure indicates that the sensor is still responding, however, the reported values are no longer representative of the measured variable, nor the occurring events in the surrounding environment that are intended to be detected.
What are the causes of sensor failure?
Dust, other contaminants, vibrations, shocks and exposure to high temperatures all have a shortening effect on the average lifespan of a sensor, so it is important to look for a solution that overcomes these problems by design, rather than just accepting frequent sensor failure and replacement as part and parcel of ...
What happens when sensor fails?
If a pressure sensor fails, it can cause the entire control system to fail and lead to inoperable equipment or system down time; depending on the type of system, significant damage can occur to the equipment and surrounding environment.
What is sensor fault detection?
In the sensor faults detection process based on neural network, the network structure and the appropriate activation function is determined according to the characteristics of the output vector dimension and the number of faults. The network is trained using the fault samples.
