The accuracy level of the load cell includes the sensor's non-linearity, creep, repeatability, hysteresis, sensitivity and other technical indicators. When selecting a high-level sensor, the accuracy level and cost of the electronic scale should not be blindly pursued.

Linearity error: This is a factor that has little effect on the initial error of the pressure sensor. The cause of the error is the physical nonlinearity of the silicon chip, but for the sensor with an amplifier, the nonlinearity of the amplifier should also be included.

The following points should be paid attention to when installing the torque sensor: 1. The matching of the coupling 2. The guarantee of the coaxiality 3. Ensure that the mechanical installation is free from external force 4. Ensure that the shaft and the shell at both ends do not constitute a three-point force

The load cell uses a metal resistance strain gauge to form a measuring bridge, and is made by the principle that the metal resistance wire stretches and becomes thinner under tension and the resistance increases, that is, the effect of the metal resistance changing with the strain received.
