I am currently using strain gauge based load cells and want to weigh 1-5kg granular products on whatever container with 4loadcells beneath. I encountered a problem with connecting load cells in a parallel position. I thought it would work, but nothing showed up as I expected. A single load cell works well with a hx711, the amplifier, but when I link four load cells, parallel doesn't work. The loadcell I use and a circuit are in the picture shown above.
What type of circuit junction box make all the loadcells in parallel contain? And how do I manage that?
Please tell me how to handle that issue most efficiently?
