TEDEA - HUNTLEIGH Model 620 S Type Load Cell Model 620 is an advanced concept in providing the weighing industry with the ultimate protection necessary for todays hostile weighing environment. Its all welded sealing combined with high accuracy, make this load cell ideally suited for lever conversions, hopper / tanks and vibratory feeders, general process weighing and force measurement applications. It is approved by OIML to R60, up to 3000 divisions. · Capacities: 500 - 5000 kg ( - lbs) · Stainless steel construction · Fully welded protection, to IP68 · For use in tension & compression · 6 Wire (sense) circuit · OIML, NTEP and EEx ia approved Hermetically sealed against moisture, the construction of the model 620 combined with polyurethane dual shielded cable enables the load cell to function in harsh environments whilst maintaining its operating specifications. The two additional sense wires feed back the voltage reaching the load cell. Complete compensation of changes in lead resistance due to temperature change and / or cable extension, is achieved by feeding this voltage into the appropriate electronics.
