ESMTS400 50kg Half-Bridge Strain Gauge Load Cell Sensor for Bathroom scales
Working Principle
When an object is placed on a sensor, gravity causes the elastomer of the sensor to undergo slight elastic deformation. The strain gauges attached to the elastomer also deform accordingly, resulting in a change in their resistance. The strain gauges are usually connected in a Wheatstone bridge circuit, and the change in resistance causes the bridge to become unbalanced, thereby outputting a faint voltage signal proportional to the gravity applied. This signal is then processed through amplification, filtering, and A/D conversion, ultimately converting it into a display of the object's weight.
