Accuracy plays a critical role when it comes to selecting any measuring apparatus. There are different classes of accuracy. Class A and B are high precision measurement classes where the devices find their applications in pharmaceuticals. Load cells belong to class C and D. Class C load cells are applicable in mechanical engineering and civil engineering. Class D load cells are useful to weigh produces like vegetables, meat, consumer goods, etc. Nowadays, class C strain gauges are also used for weighing produces.
