Hey guys this video will explain you load cell working principle and connections wheatstone bridge type of load cell and application for same.
Load cell wiring connection.
A load cell may have a cable with four or six wires.
For example di 145 di 149 and di 155 units are economical choices.
Keep in mind that if more than one laod sensor is connected to the same power supply you only need to connect the ground screw to only one ground otherwise a ground loop may be created causing additional noise.
A six wire cable besides having excitation and signal lines also has and sense lines.
It is a common misconception that the possibility to sense the actual voltage at the load cell is the only difference between 4 wire and 6 wire load cells.
When connecting a 6 wire load to a 4 wire system the sense wires should be connected to the same place as the input wires.
