Low price ESMLS07 Bellows Weighing Sensor Module for Hopper scale
Working Principle
When an object is placed on the ESMLS07 bellows sensor, the bellows undergo elastic deformation under pressure or tension, causing a change in the resistance of the strain gauge. The detection circuit converts this resistance change into an electrical signal, which is then amplified and filtered, ultimately producing an electrical signal proportional to the load, which is used to display the weight of the object.
Product Features
- High accuracy
- Strong anti-interference capability
- Good protective performance
- Strong fatigue resistance
