Load cell wiring connection.
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.
A six wire cable besides having excitation and signal lines also has and sense lines.
Hey guys this video will explain you load cell working principle and connections wheatstone bridge type of load cell and application for same.
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.
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.
