Compression Load Cell SK420

Product Characteristics:

The SK420 load cell is a column, low profile, compression load cell. The construction offers excellent insensitivity to eccentric loads whilst maintaining accuracy. Model SK420 is a high capacity truck scale and silo load cell which is supplied complete with its own unique rocker mounting components. Suitable for all heavy duty weighing applications the SK420 gives the user high accuracy and low installation cost. The two additional sense wires feed back the voltage reaching the load cell. Complete compensation of change in lead resistance due to temperature change and/or cable extension, is achieved by feeding this voltage into the appropriate electronics. The type load cell is suitable for use in truck weighbridges, silo and hopper weighing, rail scales, process weighing.
