The basic requirements and special requirements of the weighing system of engineering machinery mixing equipment are put forward. Several problems need to be considered when selecting the sensor for the weighing system of engineering machinery mixing equipment. The influence of the protective structure of the sensor on the operational reliability of the engineering machinery mixing equipment is analyzed. It is pointed out that the degree of protection represented by the IP code cannot cover the full protection requirements of the engineering machinery mixing equipment for the sensor. Different types of mixing equipment are recommended for sensors with different protection capabilities.


The selection of sensors in the weighing system usually takes into account the weight limit of the weighing system, the accuracy, the installation space of the sensor, the possible influence of the surrounding environment on the sensor, the type of loading and the life of the sensor. The weighing system of construction machinery mixing equipment is no exception. It is only the different weighing systems that have different requirements and different working conditions, and the issues to be considered are different.


Construction machinery mixing equipment usually includes concrete mixing plant (station), asphalt mixing plant, stabilized soil mixing plant and offshore concrete mixing ship, among which concrete mixing building (station) is the most typical. The following is an example of concrete mixing building (station).
First, the basic requirements of the concrete mixing plant (station) symmetric heavy system

1.1. Accurate weighing error has a great influence on the strength of concrete, especially the water-cement ratio measurement accuracy, because the strength and water-cement ratio are linear. Relevant national standards stipulate that the dynamic measurement accuracy of cement, water, admixtures and admixtures is ±1%, and the dynamic measurement accuracy of sand and stone materials is ±2%.
1.2, quickly meet the requirements of the work cycle of the mixing plant.
1.3, the type of multi-weighing pre-selection of more types, the transformation should be convenient to adapt to a variety of ratios and different capacity requirements.
1.4. Simple structure The weighing device should have a simple structure, firm and reliable performance, stable performance and easy operation.
