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.
Load cell wiring connection.
For example di 145 di 149 and di 155 units are economical choices.
A load cell may have a cable with four or six wires.
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.
Hey guys this video will explain you load cell working principle and connections wheatstone bridge type of load cell and application for same.
The following diagram will demonstrate the correct wiring configuration for a load cell to a differential input.
