Speed Tachometer

how tachometers or speed sensors work?

i know what is a tachometer but i want to know how it works in detail

The older tachs worked off of the negitive side of the ignition coil,they picked up the electric pulse coming through the ground each time the coil pulsed and divided the pulse by 4,6,or 8 depending on the number of cylinders the engine has. Most of the new tachs com straight from ECM or on board computer per the firing secqence and compute RPM the same as the other tachs.On diesel engines their is a magnetic sensor in the bell housing that picks up a magnet in the flywheel,this makes one pulse per turn of the crankshaft giving you the RPM.
