Hi,
I am looking to create a system where a load cell is attached to the end of a pneumatic ram and the ram has to move by a preset load. I am looking to create this with a raspberry pi. Any help on what way to go about this would be much appreciated
Regards,
Hi Ruddock
You will need an amplifier to be able to read the value from the load cell. It’s either called a load cell amplifier or a Wheatstone amplifier (they’re the same, by the way).
I’ll link you one which can be operated at suitable voltages for both Arduino and Raspberry Pi:
Here are it’s libraries:
Let me know if you need more help!
Thanks. Using that amplifier was my initial concept which allowed me to get an mass reading but my concern was how im going to send that data to a servo valve to move the ram at the desired force l. i also need to change forces for different application. My coding knowledge is limited as only getting into pneumatic control very recently

Hi Ruddock
If you have some time in front of you, I suggest that you familiarize yourself with C++ and C languages.
We have a short tutorial on how to use servo motors in the Arduino IDE, which is C based:
Also, unless you have some specific reason why you are using a Raspberry Pi, you might want to take a look at the Arduino-like boards. It might fit your skills better.
We also have a tutorial on how to use a Wheatstone amplifier on an Arduino:
