The four-step method of selecting electronic scale scientifically

The four-step method of selecting electronic scale scientifically Many people have the experience of weighing themselves on the scales and weighing their mobile phones on the scales, but the consequences of weighing can be very inaccurate. Because the difference of industrial environment makes the application environment of scale complex and changeable, each kind of scale has its special purpose. If in the industrial production of mixed use, wrong use, it will affect the quality of products. Only by using the proper scale, can we obtain the reliable weight result and guarantee the product quality. The "Four Steps of Choosing a scientific scale" can help friends to better choose their own scales.   Step 1: Determine the weighing environment Weighing environment refers to the external environment in which on-site temperature, humidity, dust and vibration will have a significant impact on weighing consequences. According to the different external environment, it is necessary to choose different scales to meet the needs of the site. Such as: it is very humid environment, it is necessary to choose IP grade high scale. Step 2: Determine the requirements for weighing accuracy This step is an important step in the scientific selection of scales, and it is necessary to confirm two aspects of information: (I) Process requirements It can be understood from the following three questions: What is the maximum weight that can be weighed? (including tare) What is the minimum weight to weigh? (Excluding tare) What is the weighing tolerance? The weight determines the scale; The minimum weight and allowance for weighing determine the accuracy requirements of the scale. (2) The accuracy of the scales There must be an error between the weighing result and the actual value of the scale. The error is caused by linearity, Angle difference, repeatability, lag, temperature stability, stability time and degree. Because of the different design concept and sensor instrument technology, the error will be very different. Step 3: Define the requirements In accordance with the trade settlement demarcation, if the scale used for commercial transactions is priced by weight, it must be defined as "trade settlement". The scale must meet the requirements of China's national measurement laws and regulations. Confirm explosion protection requirements Scales used in explosive environment must comply with China's explosion-proof regulations. Application building must meet the requirements of explosion-proof area. Step 4: Determine what is necessary With the development of the function of the scale, jinan electronic scale is not simply to provide you with the weighing results, choose different effects of the scale can greatly affect the production line.
