SP334A SINGLE POINT LOAD CELL
Product description:
SP334A is a typical and standard alloy steel single point load cell that is with large capacity by 2t and ideal for a wide range of weighing equipment. Environmentally sealed with potting compound to ensure reliability and durability. The industry standard size and mounting hole configuration makes the SP334A suitable for large-size platform by 1200*1200mm, or as a replacement for existed weighing equipment.
Besides for common applications of weighing equipment, it also can be used for force measurement on controlling.
