1. Basic Parameters
Model: PSA30-50 (CE certified)Capacity: 50kgBrand: BONGSHIN
Type: Plate-type weighing sensor
2. Working Principle
The weighing sensor uses a metal resistance strain gauge to form a measurement bridge. It operates on the principle that the metal resistance wire elongates and thins under tension, increasing its resistance, thus converting weight or pressure signals into electrical signals. When an object is placed on the sensor, the internal elastic beam deforms, causing the strain gauge attached to it to also deform, resulting in a change in resistance. This change in resistance is converted into a voltage or current signal output through a bridge measurement circuit, enabling weight measurement.
3. Features
