Sensor Failure - an overview | ScienceDirect Topics

· In theory, the system was designed so that if any critical sensor or communications failed, it would “fail safe” by bringing the affected trains to a halt. Clearly something failed out of keeping with anyone's predictions and was either not detected or not acted on by the critical safety systems. The ultimate backup control system—the human operator—also failed to notice or act in time to prevent …

Why is hydrogen such a big issue for CO sensors? | GfG ...

Unfortunately, although CO sensors recover rapidly from exposure to hydrogen, it can take hours or even days for the sensor to recover completely after exposure to solvent vapor or acetylene. Although CO sensors are not usually harmed by exposure to low concentrations, exposure to very high concentrations of solvent or alcohol vapor can permanently damage the sensor. Never use alcohol or …

Sensors: When to Replace Them | KnowYourParts

A failure of either sensor may prevent the engine from starting or running. Two types of sensors are commonly used for these applications: magnetic sensors or Hall effect sensors. Magnetic sensors have a wire coil wrapped around a magnetic core. When the tip of the sensor passes over a notch on a ring attached to the crank, it changes the magnetic field and produces a small current. With Hall ...
