The speed sensor element employs a brushless, pulse generator which produces a
stream of pulses, each pulse representing a unit of belt travel. The frequency of the
pulse stream is proportional to true belt speed. The pulse output signal is fed to the
Integrator/Totalizer..

The Model 60-12C supplies the output of the generator directly to the totalizer for high speed
operation (20-200 RPM).
