As was mentioned above, electrical noise must be eliminated to achieve the best load cell performance. How are connectors related? The contact resistance of connectors is usually several tens of mΩ. On top of this, the effects of temperature changes and deterioration are large. Load cells output minute analog signals of several μV. Therefore, errors caused by connectors have a large impact on its signal measurements. Naturally, the remote sensing function (of six-wire cables) is effective in this situation as well. The remote sensing function corrects changes in excitation voltage and eliminates most of the negative effects. In fact, even small connectors that can accommodate six-wire cable are more effective in correcting errors than large connectors with low contact resistance.
