Velocity Sensing System for Timing Belt

A simple sensing system to denote position and velocity of a timing belt is disclosed.

The sensing system uses a Hall-effect sensor to monitor the position and velocity of a timing belt. The nucleus of the system is a square wave shaped steel cord embedded within the timing belt. The square wave provides a magnetic discontinuity that is sensed by the Hall pickup to produce square wave pulses. The number of output pulses depends solely on the position of the grooves in relation to the pickup. A easy summation of the generated pulses gives a direct indication of belt position. Frequency of the pulses generated in a specific time period is directly proportional to velocity. Thus, the system provides an indication of both position and velocity plus strengthening the belt.
