Electronic scale sensor how to choose

How to choose an electronic scale sensor ? We all know that the sensor is an indispensable part of the electronic scale. Therefore, we must pay more attention to the purchase of electronic scale sensors. How can we get a good electronic scale sensor? ? Today, Shanghai Hengheng Xiaobian came to share with you, hoping to help everyone.

1. Electronic floor scale safety limit load, limit overload: The maximum axial load that can be applied to the load cell. At this time, the load cell will not produce a permanent drift beyond the specified value in terms of performance characteristics. When working beyond this value, the sensor will be damaged.

2. Load cell measurement range: The range of the measured mass. The measurement result will not exceed the maximum allowable error within this range.

3. Electronic scale scales: The size of one of the weighing sensors' measuring ranges is divided equally.

4. The weighing sensor verification division value: In order to accurately classify, in the load cell test, expressed in mass units weighing sensor division value.

5. Load cell output: Measured mass is converted to a measurable mass sensor.

6.. Electronic scale scale sensor minimum calibration indexing value: The smallest calibration scale value of the weighing sensor measurement range can be indexed.

7. Nonlinearity: Characterize the accuracy of the correspondence between the sensor output voltage signal and the load, specifically the deviation of the calibration curve of the load cell process from the theoretical straight line.

8. Excitation voltage: The normal voltage required for the sensor to work, typically 5~10v.

9. Insulation resistance: Insulation resistance is equivalent to a resistor and its resistance serially connected between the sensor bridge and the ground, specifically the resistance between the elastic beam of the load cell and the strain gauge.

10. Sensitivity: Ratio of output increment to added load increment. When the sensors of different manufacturers are used together, the consistency of sensitivity must be paid attention to.

11. Creep: The load cell output changes over time under constant conditions where the load is constant and all environmental conditions and other variables remain constant. Correspondingly there are creep recovery parameters.
