![]() Yes, IMHO accelerometers are a better way to go initially. This sort of thing has been done in commercial products, years ago although I don't know the details. Stangely enough, this is what I do for a living. No kidding. I am an engineer at Bently Nevada, Corp, the industry leader in machinery diagnostics. Most of our claim to fame is for rotating machinery; however, we do quite a bit of work with reciprocating engines as well. An accelerometer will work well. So will proximity (vibration) probes. We do all kinds of little tricks like putting a notch in the crankshaft to use as a phase reference. Then we can determine at what point in the cycle an anomaly occurs, which can lead to different diagnoses. We do a whole lot more, but I can't give away all of the trade secrets ;-) Adam N7966L Beech Super III |
