Weighing load cell is very common in the application of electronic weighing device. Weighing module is the heart of weighing system and electronic weighing device. Selection of load cell accuracy: for the weighing device, the higher the accuracy, the better. But the question is whether it can be bought, and whether the price is acceptable. Structure selection of weighing sensor: Generally according to the weighing device to roughly determine what structure weighing sensor, and then to the sensor sample to assist the selection. Especially under the influence of the lateral force of the weighing instrument, there are usually two kinds of sensors, shear stress and normal stress, to counter the lateral force. The number of weighing sensor is determined: according to the weighing size of the weighing device, the number of small weighing device is usually used 1 ~ 2 sensors, large weighing device is not less than two sensors. The range selection of weighing sensor: in fact, the range of weighing sensor can be selected according to the comprehensive consideration of the maximum weighing, the number of sensors used, weighing body weight, maximum offset load, dynamic load factors. In a word, the measuring range of the weighing sensor is larger than the weighing system. Packaging form selection of weighing sensor; According to the weighing instrument application environment to consider. Weighing sensor is usually used in full seal and local seal two ways, so the weighing device application environment to choose the sensor seal way. Therefore, it is true that the "heart" of the electronic weighing device is the weighing sensor, and the importance of its correct selection is indescribable.
When we choose the sensor, we start from the structure, range and packaging form of the weighing sensor, with the weighing size, use environment, installation space and other aspects as the entry point.
