Factors affecting Weight Scale Sensor

Keyword: weight scale sensor, weight cell sensor, weighing cells

A weighing cells is actually a device that converts a mass signal into a measurable electrical signal output. When using weighing cells, the actual working environment in which the weight scale sensor is located should be considered first, which is crucial for the correct selection of weighing sensors. It is related to whether the weight scale sensor can work normally, its safety and service life, and even the reliability and safety of the entire weighing apparatus. There are qualitative differences between the new and old national standards in the basic concepts and evaluation methods of the main technical indicators of weighing sensors. There are several styles available, including S-shaped weighing cells, cantilever weight cell sensor, spoke weight cell sensor, plate ring weighing cells, film box weight cell sensor, bridge weight cell sensor, and cylindrical weighing cells.

Factors affecting weight cell sensor:

1. Environmental temperature

Each substance changes with temperature, expanding with increasing temperature and contracting with decreasing temperature. The same applies to weight cell sensor and their strain gauges, which also affect the resistance of conductors. However, regardless of the ambient temperature, in order to obtain accurate measurement results, each weighing sensor should have a built-in temperature compensation mechanism.

The weight cell sensor must be able to withstand various environmental temperature influences. Such as extremely cold and high temperature environments.

2. Parasitic force

According to the installation environment of the weight scale sensor, such as placing the weighing container under the conveyor belt, other loads beyond the weight may occur. Parasitic force "not only occurs in the desired main direction, but also applies from the side and below. The weighing sensor was not developed for this purpose, and the measurement results may be incorrect or erroneous. Therefore, care must be taken during the installation process to ensure that there are no or as little parasitic forces as possible.
