Load cell can be used in weighing systems such as track scale, platform scale and floor scale. Conventional sensors are made of alloy steel, and generally include shear beam sensor, double shear beam load cell, single point load cell, and S-type load cell. Load cells used in four or more groups require junction box connection. Junction boxes are generally made of plastic and stainless steel. Usually the floor scale uses a 4-wire junction box, and the floor scale uses a 6-wire （6 Ways junction box)  or 8-wire junction box (8 Ways junction box).

The complete weighing system includes sensors, junction boxe and weighing indicator. The weighing indicator are used for weighing, counting and animal scales.
