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.
Load cell wiring connection.
Hey guys this video will explain you load cell working principle and connections wheatstone bridge type of load cell and application for same.
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.
The following diagram will demonstrate the correct wiring configuration for a load cell to a differential input.
A six wire cable besides having excitation and signal lines also has and sense lines.
Wiring the amp to the dataq unit any suitable analog to digital converter may be used to convert the analog output of the load cell amplifier to a digital signal.
The sense wires of the 6 wire load cell can be connected to the sense terminals of the weight indicator to measure and adjust the amplifier on the actual voltage of the load cells.
