Load Cell Wiring Connection

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.

The following diagram will demonstrate the correct wiring configuration for a load cell to a differential input. 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. A load cell may have a cable with four or six wires. 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.

For example di 145 di 149 and di 155 units are economical choices. A six wire cable besides having excitation and signal lines also has and sense lines.
