What is the working principle of the sensor of electronic scale?

Working principle of electronic scale sensor;

The resistance strain type weighing sensor is based on the principle that the elastic body deforms elastically under the action of external force, so that the resistance strain gauge attached to its surface also deforms.

After the resistance strain gauge is deformed, its resistance will change, and then this resistance change will be converted into an electrical signal through the corresponding measuring circuit, thus completing the process of converting external force into an electrical signal.

Precautions for installation of electronic scale sensor:

1. Load cells should be handled with care, especially for small-capacity sensors using aluminum alloy as elastomer. Any impact or drop caused by vibration may cause great output error.

2. The design and installation of the loading device should ensure that the loading axis of the load cell coincides with the loading force, so as to minimize the influence of inclined load and eccentric load.

3. In terms of horizontal adjustment. If a load cell is used, the mounting plane of its base should be adjusted with a level meter until it is horizontal.

If multiple sensors measure at the same time, the mounting surface of the base should be kept as horizontal as possible. The main purpose of this is to ensure that each sensor bears basically the same force.
