1.0 Device description
The SKF Belt Frequency Meter is a two component system consisting of a hand-held meter
attached to an optical sensor via an electronic cable. The sensor uses an infrared beam to detect
the vibration of a belt strand and sends a signal to the meter. (The sensor includes an LED that
produces an orange light beam to help aim the invisible infrared ray.) Comparing this input to
the vibration of a quartz crystal, the meter computes the natural frequency of the belt. The result
is shown in the display window as hertz (oscillations per second). The internal programming of
the meter is also able to report the belt tension in units of force (either newton or pounds-force)
provided the operator has entered the belt mass and span length using the manually operated
key pad.
The meter operates on four “AA” batteries. Battery life is approximately 20 hours. The battery
compartment is accessible at the back of the meter. This manual, a tuning fork for checking
calibration and a storage case are included with the complete kit.
