Type 4 Optical
belt tension meter
Features
- High accuracy, efficiency and repeatability.
- large and clear Font height: 12mm.
- no need to enter the unit weight and span of the belt
- Maintain and adjust belt tightness without confusion of any key-in data
- Avoid intangible loss belt drive, make sure the belt life
- maximum the motor / engine power transfer.


An additional advantage of the optical head is that the sensor is totally unaffected by any level of background acoustic noise.
Ducati Motorcyles have for a long time realised the importance of accurate belt tension setting, both to ensure long belt life and to maximise performance. Ducati asked to produce equipment to be used on their production lines to set belt tension and a handheld meter for use by their racing teams and dealer network.
Engineers designed the handheld meter to use an optical sensor which could be 'beamed' onto either the flat face of the belt or the edge of the belt. This was of particular importance as the belt is quite heavily masked when the engine is located in the frame.
The sensor has an adjustable depth stop so that it can be rested on the timing casing behind the belt. Although optical meter is typically a low frequency unit from 10-300Hz, we extended the range to 600Hz to cover all possible belt applications.
