Basic requirements of concrete mixing station for weighing sensor

1. The accurate weighing error has a great influence on the strength of concrete, especially the measurement accuracy of water-cement ratio, because the strength and water-cement ratio are linear. According to relevant national standards and rules, the dynamic measurement accuracy of cement, water, admixture and admixture is 1%, and that of sand and stone is 2%.

2. Quickly meet the requirements of the working cycle of the mixing station.

3. More varieties, more varieties should be pre-selected, and the change should be convenient to meet the requirements of multiple ratios and different capacities.

4. Simple structure The weighing device should be simple in structure, firm and reliable, with stable performance and simple operation.

Therefore, electronic weighing with sensors can meet the requirements better than mechanical weighing. Therefore, the weighing sensor has been more and more widely used in the concrete mixing station. However, objectively speaking, compared with mechanical lever scale, sensor electronic weighing sensor still has a lot of work to do in terms of "firmness, reliability and stable performance".
