Load Cell Wiring Connection

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.

Load cell wiring connection.

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. 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. 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.

A six wire cable besides having excitation and signal lines also has and sense lines. 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.
