For some reason when this post began I had it in my head that we could look at belt tension whilst running as part of routine service.
Steve, a few notes...
It would appear after entering specific details about the belt (Including Mass) by tapping on the belt with microphone positioned in close proximity, we can acquire a tension result.
It only works on Gates Belts, don't try it on other makes you'll be upset.
I cannot believe I have never heard of such a device which does concern me as I wonder just how many workshops are equipped with such a device and more importantly how many of those are using them?
I have if memory serves me correctly owned the tension tester since about year 2000.
I would be very interested to know just how simple the process would be and how vulnerable the results are to incorrect use?
It's possible that Gates have updated it since I bought mine, must admit to not having used it for a long time, there is also a chip inside which is update able as technology moves on.
The inductive sensor sounds intriguing too whereby a magnet is secured to the "flat" side of the belt whilst the deflection of the belt is measured by the inductive sensor.
I can see this option removing some of the many variables associated with a microphone, Gates themselves claim this is the desired electronic belt tension measuring method in windy conditions.
These last two sentences read like updates I think?
Here technician would apply the microphone within the timing belt service port, (where applicable) enter in vehicle/belt details and run the engine!
I guess that was a bit science fiction but not impossible if the formulas exist, however, there would simply be thousands of variables.
Back in my day there were no service ports, the microphone was simply held very close to the belt and the belt was flicked with your fingers
What we choose to believe is science fiction Steve in reality is not, take the TV program the car KIT and Micheal Knight, back then everyone thought its science fiction on TV, try getting away with that today?
Both the microphone and the inductive sensor could be added to PicoScope with no issues, (possibly a feature of Pico Diagnostics) the challenge would be for the software to calculate the tension based on the formulas used by Gates.
I don't see too much of an issue with the calculations for tension and creating formulas to be honest, there are some very bright people in our industry
