A load cell 20Kg (weight sensor - strain gauge) is a type of electronic sensor that measures force or strain by using the principle of resistance change. It consists of a metal bar with four wires attached to it, which form a wheatstone bridge circuit. The metal bar is made of aluminum alloy, which has a high elasticity and durability. When a force or pressure is applied to the bar, it causes a slight deformation, which changes the resistance of the circuit. The change in resistance is proportional to the amount of force or pressure, and can be converted into an electrical signal by using an analog-to-digital converter (ADC). The load cell can measure the weight of objects up to 20 kilograms with high accuracy and sensitivity.
Features:
- High precision and sensitivity: The load cell can detect small changes in force or pressure and provide accurate readings.
- Easy to use: The load cell has four color-coded wires that can be easily connected to an ADC or a microcontroller.
- Versatile: The load cell can be used for various applications, such as measuring pressure, force, weight, and tension.
