Acceleration sensor > measurement dependant on frequency

[SimonHW2021]

Hi there,

I am looking for an acceleration sensor which gives me the acceleration over the frequency. It should look something like this:

The problem is that the market seems quite in-transparent for me. I can find prices for the same sensor varying from 100-500€. Is there anyone with experience in acceleration sensors who can give me a hint on which sensor and controller to use and where to buy them? I would prefer a distributor in EU.
