There are a lot of important characteristics that must be incorporated in
Floor Scales to provide precise trouble free use. The most important one is associated to the load cells. These types of scales provide a load cell in every corner of the platform. The cells will bend by very minute amounts when a load is placed on the platform. Strain gages will exactly measure the amount of bending that occurs, and send their signals to the digital indicator that is to be processed for the weight display.
As the load cell is intended to accept the rated load, industrial environments often results in situation where the instantaneous load may be higher than rated. This might occur when a forklift drops a pallet onto the scale platform. Though the pallet only weighs 2,000 lb, the force of a small drop may produce loads that are many times higher. This is even more likely to happen if the load is very dense. There is a tough likelihood that a significant shock load would cause the force on the material to exceed the modulus of elasticity. This would permanently affect the load cell, and will result in large shifts of the production signal, and of the accuracy of that signal. The load cell should be replaced in this case.
