Valve spring tester

[Janetm]

I am looking for a valve spring tester that can log the data to compare springs, preferably in kit form to adapt to my current tester, if any could help in any way.
Many thanks

I think the only way to do this is a custom made system and adapt it to your system.
You can buy two transducers one for the force and another for the desplacement (desplacement potentiometer), and introduce both signals on your data adquisition system.

Seems to be easy, but you need to expend a little bit of time.
