A load cell is actually an output device that converts a mass signal into a measurable electrical signal. When using a sensor, we must first consider the actual working environment of the sensor, which is very important for the correct selection of the sensor. It is related to whether the sensor can work normally, its safety and service life, and even the reliability and safety of the entire weighing instrument. Under normal circumstances, the high temperature environment will cause problems such as melting of coating materials, opening of solder joints, and structural changes in the elastic body; dust and humidity will cause short circuit effects on the sensor; in a highly corrosive environment, it will cause the sensor elastomer Damaged or short-circuited; electromagnetic fields will interfere with the sensor output. Under the corresponding environmental factors, we must choose the corresponding load cell to meet the necessary weighing requirements.
