ZEMIC Load Cell
The application of the Zemic load cell in the weighing system is very important. If you compare it to the heart, it is not an exaggeration. It is indeed like the heart in the weighing system. Its performance determines the accuracy and stability of the weighing system.
Let's talk about four aspects that should be paid attention to when choosing a Zemic load cell: #zemicloadcell
1:About the accuracy of the zemic load cell
Accuracy is a very important performance index of the sensor zemic load cell. Relatively speaking, the higher the accuracy of the product, the higher the price. It is an essential part of the zemic load cell sensor's measurement system. So when we choose to choose, as long as it can be used within our use range, it does not need to be too high, which will cause cost pressure, but if it is necessary to measure precise values, then we must choose high-precision. #Single-EndedBeamsLoadCell,#Loadcellsandloadcellunits,#weighingloadcell,#weighingloadcellsensor
2 points can be selected as precision options:
1.Meet the accuracy requirements of the entire electronic scale. An electronic scale is mainly composed of a scale body, a Zemic load cell sensor, and an instrument. When selecting the accuracy of the Zemic load cell sensor, the accuracy of the sensor should be slightly higher than the theoretical calculation value.
2.Meet the requirements of instrument input. The output signal of the Zemic load cell sensor must be greater than or equal to the input signal required by the instrument

2:The most important point is the choice of zemic load cell stability
Stability means that the performance of the sensor zemic load cell is still very good after being used for some time. It is called stability. Of course, there are still many factors that affect stability. In addition to its own performance, one of them is environmental impact. Therefore, to make the sensor zemic load cell have a strong environmental adaptability, we must first select the load cell to the surrounding environment Do a simple survey, select the appropriate sensor zemic load cell, or do some corresponding measures to reduce the environmental impact. Normally, sensors zemic load cell with very strong environmental adaptability will be slightly more expensive.
2.1.In a high temperature environment, the structure of the elastomer may change, so high temperature resistant sensors Zemic load cell should be selected.
2.2.In open-air environment, sun and rain, moisture-proof sensors Zemic load cell should be considered.
2.3.In a highly corrosive environment, acid or humidity will damage the sensor and short-circuit. In this environment, you should choose an anti-corrosion sensor Zemic load cell, like stainless steel is better.
2.4.The place of electromagnetic interference will cause the sensor signal to be disordered, resulting in inaccurate test data. Of course, this function is generally available, but when the impact is too large, you can use the aluminum box to be fully enclosed and multi-layer shielded wire And a shielded wire with a thicker shielding layer that is not easy to break down.
2.5.In flammable and explosive environments, explosion-proof sensors must be selected.
The stability of the sensor Zemic load cell is generally standardized, and it can only be used after the time has expired to be re-calibrated, so as to ensure whether it can be used again. For some occasions when the sensor Zemic load cell has a long service life and cannot be easily replaced, the first Select the sensor Zemic load cell to be more stringent, so as not to cause unnecessary losses.
3:The selection of the range size of the zemic load cell
Simply put, the selection of the sensor zemic load cell range can be determined based on the comprehensive evaluation of factors such as the maximum weighing value of the scale, the number of sensors to be selected, the weight of the scale itself, the maximum possible partial load and the dynamic load.

4:The sensitive selection of zemic load cells
Now everyone says that within the linear range of the load cell, the greater the sensitivity, the better. This way, signal processing is used. However, if it is not paired well, and the sensitivity is too high, the overload cannot be tolerated, which will lead to serious consequences, and the zemic load cell sensor's service life Some problems such as shortening, inaccurate precision, etc. appear, so it is the old saying that you have to choose the right one is the best.
