These are mainly Hall-effect sensors and are monitored by a circuit that looks at the pulse frequency to measure fan RPM. It would be nice to have a box that would support multiple such circuits and turn on appropriate warnings when the RPM of a device fell below a set parameter - plus offer signal outputs for use by other devices, such as an EM. (Sorry, I can *fix* circuits, but I don't make them. I *make* chips/shavings.) Dale R.
