A load cell measures mechanical force, mainly the weight of objects. Today, almost all electronic weighing scales use load cells for the measurement of weight. They are widely used because of the accuracy with which they can measure the weight. Load cells find their application in a variety of fields that demand accuracy and precision,our customer use load cell on Treax Pad .The force indication scale may be activated either by hand or foot to exercise either upper or lower extremities. When the appropriate mode is chosen, the pads react to the amount of force or weight applied to each of them. The light scale at the front of the pads responds dynamically to change in force or weight applied by the user. The feedback clarifies and aids understanding of how changes in motor actions or body posture affect the force or weight applied to the pads.
