Self mixing concrete mixer. Weighing is a very important link in the concrete mixing plant. In order to ensure the production of high-quality concrete, it is necessary to weigh the concrete raw materials. Therefore, the weighing system in the concrete mixing plant needs the following requirements:
自拌混凝土攪拌車。擴大溫度和濕度範圍需要。混凝土攪拌站的工作環境與一般的商貿計量的電子秤不同，一般的商貿計量的電子秤的工作環境一般相對穩定，而移動式混凝土攪拌站中荷重傳感器的應力環境十分複雜，運行條件相對更加惡劣，有更大的隨機性。混凝土攪拌站通常是露天安裝，傳感器經常遭受日曬雨淋，溫度處於很大的變換狀態。
Self mixing concrete mixer. It is necessary to expand the temperature and humidity range. The working environment of the concrete mixing plant is different from that of the general commercial scale. The working environment of the general commercial scale is generally relatively stable, while the stress environment of the load sensor in the mobiles concrete mixing plant is very complex, the operating conditions are relatively worse and have greater randomness. The concrete mixing plant is usually installed in the open air. The sensor is often exposed to the sun and rain, and the temperature is in a great change state.
自拌混凝土攪拌車。耐腐蝕性要求更高。混凝土攪拌站的工作環境十分惡劣，不僅溫度和濕度都有很大的浮動空間，還存在一定的腐蝕性。混凝土在生產過程中需要大量的水泥、煤粉灰以及適量的外加劑，這些粉狀物在輸送和稱量過程中會產生粉塵。這些粉塵有一部分會附著在稱重傳感器表麵。在粉塵和水氣的共同作用下，傳感器將受到較為嚴重的腐蝕。
Self mixing concrete mixer. Higher corrosion resistance requirements. The working environment of concrete mixing plant is very bad. There is not only a large floating space for temperature and humidity, but also a certain corrosivity. A large amount of cement, pulverized coal ash and an appropriate amount of admixture are required in the production of concrete. These powders will produce dust in the process of transportation and weighing. Some of this dust will adhere to the surface of the load cell. Under the combined action of dust and water vapor, the sensor will be seriously corroded.
自拌混凝土攪拌車。需要進行一些特殊設計。混凝土攪拌站一般安裝在施工現場，工作人員的工作素質也會影響稱重係統的使用情況。工地上大量使用臨時工，其中相當多的臨時工文化水平較低，缺少必要的技能。在設備的維修和清洗等工作中，很有可能發生傳感器受到高壓水的濺射，誤操作引起過載等情況。傳感器要在這樣的環境條件下長期可靠的運行，是要進行一些特殊設計的。
Self mixing concrete mixer. Some special design is required. The concrete mixing plant is generally installed on the construction site, and the working quality of the staff will also affect the use of the weighing system. Temporary workers are widely used on the construction site, and a considerable number of them have low educational level and lack necessary skills. In the maintenance and cleaning of equipment, it is likely that the sensor will be sputtered by high-pressure water and overload will be caused by misoperation. The sensor needs some special design to operate reliably for a long time under such environmental conditions.
