I have a 3 wire load cell, Which I would love to use for a project to measure weight But Most load cells come with 4 wires, however, The ones I have found in my weiging scales are 3 wires, does anyone have any ideas on how I would connect them to a Arduino?
I have attached some Pics as I'm not very good at explaining this stuff. I have no datasheet for this, and the only marker I could see on the load cell was a 8964f. the PCB picture may shed more light on how this load cell was connected.
Load Cell up close
I'm wondering if the white wire is the signal wire and back and red are ground and power respecivley, any way you can test this? Just going off this blog post I've seen below.
or have I a load cell with an inbuilt amplifier?http://www.electro-tech-online.com/general-electronics-chat/96880-3-wire-load-cell.html
