There are many kinds of load cells on the market. How to choose the load cell has become a problem to consider. To select a load cell, we must comprehensively measure it, mainly from the structure, environment, range size, accuracy selection and sensitivity.
1. Structure and environment
We can choose the load cell according to the structure of the instrument and the environment in which it is used. If you want to produce low-profile scales, the cantilever type is generally used. If the shape of the scale is not strict, you can use the column type. If the environment is humid, there is a lot of dust, you should choose a sealed type; if it is in an explosive environment, you should choose a safe type; if you are in a high temperature environment, you should choose a load cell with a water-cooled jacket; if it is in an alpine region Select the sensor with the warming device.
2, the size of the range
The closer the weighing system's weighing value is to the rated capacity of the sensor, the higher the accuracy of its weighing. It is therefore possible to select the range of the sensor based on the maximum weighing value of the weighing system.
3, precision selection
Accuracy is an important performance indicator for load cells and is one of the most important aspects of the entire measurement system. The higher the accuracy of the load cell, the higher the price, so as long as the accuracy level of the load cell can meet the requirements of the weighing system.
4, sensitivity
The higher the sensitivity, the larger the output signal value corresponding to the measurement, which is beneficial to signal processing. However, when the sensitivity is high, external noise that is not related to the measurement is amplified to affect the measurement accuracy. Therefore, the sensor itself should be required to have a high signal-to-noise ratio and minimize interference signals introduced from the outside.
