1 Load cell is a high-precision measuring instrument, which is widely used in various weighing systems. Its working principle is based on the principle of resistance strain, that is, when the load cell is subjected to gravity, its internal resistance will change accordingly, which will cause a change in the output signal.

2 Load cells are mainly composed of elastomers, resistive elements and signal conditioning circuits. When an object is placed on a load cell, the elastomer will deform, causing a change in the resistance of the resistive element. This change is converted into an electrical signal output by the signal conditioning circuit, which gives the weight information of the object.
3 The selection of load cells is an important part of weighing system design. When selecting a load cell,It is necessary to consider factors such as range, accuracy, material, stability, and reliability。The range determines the maximum weight that the sensor can measure, and the accuracy reflects the measurement error of the sensor. Sensors with good stability can maintain accuracy for a long time, while sensors with high reliability can work stably in various environments.
4 In practical application, the load cell also needs to pay attention to the installation method, protection level and other factors. The correct installation method ensures the accuracy of the sensor's measurements, while the degree of protection determines the conditions in which the sensor can operate. For example, in some harsh environments such as high temperature, high humidity, and high dust, it is necessary to choose a sensor with a higher protection level.
5 In conclusion, load cells are an indispensable part of a weighing system. Understanding how it works and the factors that make it possible to better design, use and maintain your weighing system.
