Engine Speed Meters

Engine speed meters used in aerospace manufacturing and test environments measure rotational velocity of turbine, compressor, and accessory-drive shafts in units of RPM or percentage N1/N2/N3 spool speed, employing technologies such as magnetic pick-ups, optical encoders, and eddy-current sensors interfaced with digital tachometer instrumentation to validate engine performance against type-certificate specifications during bench testing and MRO inspection.
