Hardy C2 - Load Sensor Cable for Weighing System

Eight conductors carry the signals to and from the weight controller and the junction box up to 1000 feet away. Each conductor is 22 AWG stranded copper wire for flexibility. The cable has a braided, tinned copper shield and a mylar barrier tape wrap. The outer jacket is vinyl and is 0.060" thick.

Hardy C2 Certified Cable has been designed specifically for the electrically and mechanically harsh environments found in Process Weighing applications. While many process variables are transmitted at a 0-10 volt or 4-20 milliamp level, signals from load or force sensors are typically one thousand times smaller, or 0-0.010 volts. A ten pound change on a 100,000 pound scale would correspond to a signal change of 0.000001 volts (1 micro volt). Therefore, cabling must protect against electrical noise common in the plant environment.

It is also imperative that moisture not enter the cable as it would increase capacitance and allow coupling of voltage from the excitation wires to the signal wires. The coupling of voltage causes “drifting” weight indications. Use of improper cable between even the finest load sensors and instrumentation will yield poor weighing results. The costs and time delays of removing and replacing improper weighing system cable are prohibitive. To insure an effective weighing system, always specify Hardy C2 Certified Cable.
