High precision ESMLS02F S-type tension and compression load cells sensor for platform scales sensor hopper scales and crane scales
Working Principle
ESMLS02F S-type load cells are usually composed of an elastic body made of high-strength alloy steel or stainless steel and strain gauges. The strain gauges are precisely attached to the part of the S-shaped elastic body that is most susceptible to deformation. When a force is applied to the top or bottom of the sensor, the middle 'beam' of the S-shape undergoes slight bending, causing the strain gauges attached in this area to be stretched or compressed, which changes their resistance. This disrupts the initial balance of the Wheatstone bridge, and a tiny voltage difference proportional to the applied force appears at the bridge's output. After amplification and processing, this signal finally displays the force or weight value.
