BELT MEASUREMENT
UNIT MOUNTING PLATES
Customised and designed specifically for individual applications (i.e. specific engine, final belt drive), the mounting unit is completely wireless and has a built-in electromechanical hammer to force the belt into oscillation.
FIXING THE UNIT IN PLACE
DETECTING BELT VIBRATION
The unit measures the natural frequency of vibration of a belt span. This frequency is directly related to the tension in the belt. As the tension in the belt is increased the frequency of vibration also increases.
An electromechanical hammer built into the unit forces the belt into oscillation. The hammer agitates the belt approximately 1 every second.

The vibration of the belt is converted into an electrical signal by the optical module in the sensor head and the conversion circuitry on the main PCB.

The optical module consisting of an infra-red LED and photodiode converts the light reflected from the belt and is subsequently amplified and filtered. This technique called synchronous demodulation and is employed to remove noise from the signal (such as that produced by background lighting).
