In the field of weighing for concrete batching plants, the BLR-12(1) load cell has become the industry's preferred choice thanks to its outstanding stability and accuracy. This article compares measured data with similar products such as CST-503 and ZRN607, and analyzes the technical advantages of BLR-12(1) in anti-interference performance, environmental adaptability, and long-term stability, providing professional selection reference for technical evaluators.

I. Industry Background and Market Demand Analysis

As the construction industry continues to raise its requirements for concrete quality, batching plants have set higher standards for the accuracy and stability of weighing sensors. As the core component of flow control equipment, weighing sensors need to maintain long-term stable operation in harsh environments with high dust, strong vibration, and large temperature differences. Relying on the R&D advantages of the national-level Xixian New Area, Xi'an Shenghongchuang Instrumentation Co., Ltd. developed the BLR-12(1) series specifically for the special operating conditions of batching plants. By optimizing the strain gauge layout and sealing structure, it achieves a comprehensive accuracy of 0.03%FS, far exceeding the requirements of ISO376:2011. Market research shows that in batching plant equipment upgrade projects in Northwest China, systems using BLR-12(1) sensors have reduced the system failure rate by 67% compared with traditional products.

II. Comparison of Key Technical Parameters

Measured data shows that in a continuous 2000-hour full-load test, the zero drift of BLR-12(1) was only 0.02%FS, while similar products were generally above 0.05%FS. Its special alloy elastomer material keeps the temperature effect coefficient within 0.002%FS/℃, making it particularly suitable for use in Northwest China where day-night temperature differences are large. To address the electromagnetic interference commonly found in anti-corrosion mixing plants, the built-in RFI filter in this product can suppress signal noise to below 10mV.

III. Analysis of Typical Application Scenarios

In a retrofit project at a commercial concrete batching plant in Shaanxi, the BLR-12(1) sensor successfully replaced the original WH02 model product and solved the following pain points: 1) the indication fluctuation caused by vibration during aggregate weighing was reduced from ±3kg to ±0.5kg through a dynamic compensation algorithm; 2) it still maintained IP68 protection performance when humidity reached 95% during the rainy season, preventing internal circuits from moisture damage; 3) it seamlessly interfaced with the NR-LZ1 controller to achieve automatic temperature compensation. After implementation of the project, the error in the concrete mix ratio for each batch was reduced from 1.8% to within 0.5%, saving more than 120,000 yuan in raw material costs annually.

IV. Technical Guide for Procurement and Selection

Technical evaluators should focus on: 1) the measuring range should be selected as 120% of the actual maximum load, for example, for a batching plant commonly using a 30t hopper, the HGZS1-36t model is recommended; 2) check the OIML R60 certification documents to ensure legal metrology compliance; 3) verify the compatibility of the sensor with transmitters such as CYT-201A. For applications with explosion-proof requirements, the TH2 explosion-proof model compliant with ATEX standards should be selected. The LK-4016 series supporting instruments provided by Xi'an Shenghongchuang support multi-sensor parallel networking and are particularly suitable for multi-point weighing systems in large batching plants.
