Signals for tachometers can be pickedup in many different ways: wireless, hall sensosrs, optical sensors .. to name just a few ..
Here is one example that shows a magnetic pickup device .. see picture below ..
This signal cen be fed directly to almost any tachometer circuit .. here is one example:

tachometer is just the current speed of the shaft or something but odometer gives the distance or the no. of revolutuions the shaft has undergone till then..
Hence the readings would be different...

I've done some readings on how tachometers (as in automobile tachometers used to measure engine RPM) works. Apparently modern tachometers drive the needle from the signal received from its signal wire; which is a series of square wave pulses. If I'm not mistaken the frequency determines what RPM the engine is running. So as a holiday project (...)

The input current usually goes up when stalled or overloaded. This can be sensed. A more sophisticated method is to use a tachometer to measure the shaft rotation speed.
