Pressure sensors protection from wear

[pietro82]

Hi all,

I need to install some pressure sensors along on the tyre surface of a construction machinery. How could protect this sensors from the wear? By using silicone? Wich type of silicone would you suggest me? Any suggestion is appreciated

Thanks

Silicones are not abrasion resistant. Urethanes are generally much better.

It's interesing, but I have the feeling it compromise the sensor sensitivity. What do you think about?

If you had room to mount the sensor deeper, maybe you could get a custom miniature load cell with a replaceable load button.

Wear on the button wouldn't affect the load cell accuracy.
