1. Accuracy level of the sensor The accuracy level of the weighing sensor includes the technical objectives of nonlinearity, creep, repeatability, hysteresis and sensitivity of the sensor. In the selected time, the high-level sensor should not be blindly pursued. Balance accuracy and cost. Under normal circumstances, the total accuracy of the selected sensor is the sum of the nonlinearity, non-repetition and lag. The rms value is slightly higher than the accuracy of the scale.

2, the scope of application of various types of sensors The choice of the weighing sensor method depends on the type of weighing and equipment space, to ensure that the equipment is suitable, weighing is safe and reliable; on the other hand, think about the manufacturer's recommendations. As far as the load cell manufacturer is concerned, it usually rules the stress state, performance target, equipment mode, construction mode, and elastomer material.

3, the use of the environment The load cell is actually a kind of electrical signal output device that converts the quality signal into a measurable. Sensors must first consider the practical operating environment in which the sensor is located. This is critical to the accurate selection of the sensor. It is related to the normal operation of the sensor, its safety and service life, and even the reliability and safety of all instruments.

Under normal conditions, the high-temperature environment has problems in the formation of coating data melting, solder joint opening, and elastic body stress on the structure; the influence of dust and moisture on the short circuit of the sensor; in the corrosive environment, the sensor elastomer is formed. Damaged or short-circuited; electromagnetic fields can disturb the sensor output.
