AbstractThe paper presents and discusses how to use some techniques to reduce the effect of error in the weighting signal which is produced from a load cell. The load cell is one of succeful sensors which is used to transform the weight to an electrical signal. In industry the production of an accurate signal suffers from a problem of noisy environment. Different source of noise like electromagnetic fields from motors, machines, power lines and microwave in addition to humidity and tempreture variations have significant effects on weak electrical signals produced by load cells.Both hardware and software filtering are adopted to reduce the un wanted effects.
