1.Determine the weighing environment: Weighing environment refers to the external environment in which symmetrical weighting results such as temperature, humidity, dust and vibration on site will have a significant impact. According to the different external environment, different scales need to be selected to meet the needs of the site.
2.Determine weighing accuracy requirements: This step is the most important step in the scientific selection of weighing scale. Two aspects of information need to be confirmed. First is technological requirements, and the second is accuracy of scale. There will be errors between the weighing results and the real values. The errors are caused by the factors of linearity, angle difference, repeatability, lag, temperature stability, stability time and indexing. Different scales have different errors due to different design concepts and sensor and instrument technology.
3.Defining regulatory requirements: you should compliance with trade settlement regulations. If the scale is used to price commercial transactions by weight, it must be defined as "trade settlement". Scales must meet the requirements of China's National Metrology laws and regulations. Confirmation of explosion-proof requirements, Scales used in explosive environments must comply with China's explosion-proof regulations. Use of equipment must meet explosion-proof zone requirements
4.Identifying application requirements: With the development of the scale function, the scale is not only simple to provide you with weighing results. Choosing scales with different functions can greatly affect the efficiency of production line.
Actually, it’s really difficult to choose the right scale. You should search lots of information.
