As we all know the accuracy of weighing sensor should be how to choose?

Weighing sensor to a great extent, determines the precision and stability of the electronic scale. In the design of electronic scales, often face the weighing sensor selection problem. According to the conversion method, weighing sensor factory engineer said: this product can be divided into photoelectric type, hydraulic type, the electromagnetic type, capacitance type, magnetic transformation type, vibrating, gyroscope and resistance strain type 8 kinds, widely used in the resistance type weighing sensor. Weighing sensor is, in fact, a kind of measuring instrument equipment electrical output signal quality. First want to consider the work environment of weighing sensor, and then select the weighing sensor. Weighing sensor using the environment related to the work of the weighing sensor, safety and service life. Therefore, must be considered in the selection process. According to the scope of the weighing sensor, using the number of weighing sensor, weighing scales, load and dynamic load, the weight of the factors such as selecting the biggest weight value for comprehensive evaluation. However, in actual use, in addition to the load on the weighing sensor, there are weighed, tare weight, unbalanced load and vibration impact load. As a result, many factors should be considered when choosing weighing transmission device, to ensure the safety and service life of the weighing sensor. Weighing sensor factory engineer said: no matter you use which kinds of weighing sensor, its precision plays a very important role, because the rating of the weighing sensor range and accuracy of different grade, the accuracy of strain technology level is usually C and D, and which has the function of electronic correction strain weighing sensor precision level is higher, therefore, the weighing accuracy of the weighing sensor must be strictly, for low cost goods, do not need very precise weighing sensor, but D precision is enough. For drugs, requires the highest accuracy grade a or B. For a one of the most common consumer products such as meat and vegetables, the accuracy of weighing sensor level is enough. Accuracy is an important performance index of the weighing sensor, it is related to the measuring accuracy of the measurement system, the higher the accuracy of the weighing sensor, however, the higher the price. Therefore, as long as the accuracy of weighing sensor meets the demand of the precision of measuring system, you don't have to choose a high precision. So, from the choose the more appropriate weighing sensor, weighing sensor to meet the same measuring purpose. If the purpose of measurement is the qualitative analysis, should use repeated high precision weighing sensor, should not use the absolute value of high precision weighing sensor. When used for quantitative analysis, must be accurate measured value, need to select precision meet the requirements of high precision weighing sensor.
