ABSTRACT:
This invention relates to a revolution indicator housed inside a casing. The indicator has a plurality of wheels with the numerals 0-9 on the outer periphery of the wheels. The numerals are viewed through a window from the outside of the casing. Each wheel is also encoded magnetically such that each wheels' rotational position can be determined electronically. The rotational position of each wheel can be displayed electronically at a remote location outside the casing.
