Technical Challenges and Breakthroughs in High-Temperature Industrial Weighing

In applications such as reaction kettles and mixing stations in industries like chemicals and metallurgy, ambient temperatures often exceed 150℃, causing traditional weighing sensors to experience issues such as zero drift and reduced sensitivity. The RSW-L254 column-type load cell, developed by Xi'an Shenghongchuang Instrument Co., Ltd. over 18 months, adopts a special alloy elastic element and a high-temperature compensation circuit, demonstrating impressive stability in the latest tests.

Core Test Parameters and Industry Comparison

The tests were conducted in accordance with the GB/T7551-2008 "Load Cell" standard under temperature gradients of 80℃~200℃:

Analysis of Key Technological Innovations

The outstanding performance of RSW-L254 comes from three major core technological breakthroughs:

• Multi-layer temperature compensation system: A temperature sensor array is integrated inside the sensor to correct in real time the parameter changes of the strain gauge caused by thermal expansion
• Special alloy sealing technology: A nickel-based high-temperature alloy housing is used to ensure the long-term stability of the internal circuit in corrosive gas environments
• Dynamic load calibration algorithm: An embedded processor is used to achieve temperature-load coupled compensation, reducing full-scale error by 60%

Measured Data from Typical Application Scenarios

Performance in Reaction Kettle Weighing Systems

In 6 months of continuous monitoring of a 180℃ reaction kettle at a chemical enterprise, comparisons of RSW-L254 with models such as RSW-L34 and RSW-L16S showed:

• Weekly cumulative error of only 0.05 tons （full scale 200 tons）
• Protection level maintained at IP68 in a strong acid steam environment
• Average trouble-free operating time reached 8000 hours

Overload Protection Application in Mixing Stations

The RSW-L254-D product designed for concrete mixing stations has been improved based on the EVT-20 sensor:

1. Impact load تحمل capacity increased to 150%FS
2. Equipped with a wireless transmission module for real-time monitoring
3. Passed 3C certification and explosion-proof certification （Ex ia IIC T6）
