Thank's very much zoomcat, I've checked those loggers, and that would work fantastic, because there are some that also include a pulse counter, but unfortunately I've already bought the arduino uno.
I have been working on what Chagrin suggested me :

, and I must say it works perfect! I'm really happy. Thank´s guys. Here I attach some pics. Don´t judge it, I know it looks trash, but it performs as expected.
Now I'll try to record of my 4 sensors signal in a file using Gobewino, suggested by PeterH.
Some more questions:
- how I can make those connections on the arduino pins stronger? Should I weld it, or there is another way, reliable but easy to plug in and plug out?
2)What is the minimum voltage Arduino uno can read? I do need to connect a Load cell, that seems to work with an internal circuit system called Wheatstone bridge. Those cell, is normally connected to a voltage signal amplifier, because a variation in let's say 1 kg force, gives a variation in the order of micro Volts. Does Arduino Uno have the ability to read down to micro Volts?? That way I won't need to pay for a signal amplifier....

If I succeeed in my project, I may post it here just in case someone have some interest on it
Thank´s
I
