Key Challenges and Solutions for Tensile and Compressive Force Measurement in the Chemical Industry

In modern chemical production, the operational stability of core equipment such as reactors and mixing stations is directly related to product quality and production safety. As an important part of equipment monitoring, insufficient accuracy in tensile and compressive force measurement may lead to material ratio imbalance, equipment overload, and even safety accidents. Traditional measurement methods often face problems such as environmental corrosion and dynamic load interference, while the EVT-20 weighing sensor provides a highly reliable solution for chemical enterprises through column-type force measurement technology.

Core Technical Advantages of the EVT-20 Weighing Sensor

The EVT-20 adopts a fully sealed stainless steel structural design with a protection rating of IP68, capable of withstanding corrosion in strong acid and strong alkali environments. Its core advantages are reflected in:

• High-precision strain gauge technology: Measurement accuracy reaches ±0.05%FS, meeting the stringent requirements of chemical process control
• Optimized dynamic response: 20ms fast response time, effectively capturing instantaneous force changes during the mixing process
• Temperature compensation system: Built-in bimetal compensation sheet, with temperature drift less than 0.01%/℃ within the range of -20℃~80℃

Compared with similar products such as RSW-L51 or SMW-H-6A weighing sensors, the EVT-20 performs particularly well in long-term stability, maintaining the initial accuracy within ±0.1% even after 3000 hours of continuous operation.

Typical Application Scenario: Monitoring of Reactor Anchor-type Mixing System

On the styrene production line of a large chemical enterprise, the EVT-20 was integrated into the support structure of the mixing shaft of a 20m³ reactor. By monitoring the following key parameters in real time:

After 12 months of system operation, unexpected equipment downtime was reduced by 67%, while the stirring speed curve was optimized through force value data, increasing reaction efficiency by 15%.

Multi-sensor Collaborative Measurement Solution

For the complex operating conditions of large mixing stations, Xi'an Shenghongchuang has developed a matrix measurement network based on EVT-20 and RSW series sensors:

1. Foundation support monitoring: 4 EVT-20 units distributed at 90°, collecting force distribution on the columns
2. Dynamic compensation measurement: RSW-L95 high-frequency sensor captures vibration harmonics
3. Safety redundancy design: RSS-5N serves as a backup sensor to ensure data continuity

In the application of a pesticide formulation plant, this solution successfully provided early warning of 3 risks of mixing shaft fracture, avoiding direct economic losses of more than 2 million yuan.

Professional Recommendations for Selection and Installation

To ensure the reliability of the measurement system, attention should be paid to:

• Range selection: The actual maximum load should be within 60-80% of the sensor range
• Environmental adaptation: For corrosive environments, it is recommended to select the special coating version of RSW-34D
• Signal transmission: For distances exceeding 30 meters, 4-20mA output or RS485 communication should be used

According to the GB/T7551-2008 "Weighing Sensors" standard, on-site calibration is recommended every 6 months, shortened to 3 months under high-temperature operating conditions.

Evolution of Measurement Technology for Improving Chemical Production Efficiency

With the development of intelligent manufacturing, weighing sensors are transforming from single measurement units into intelligent nodes. The EVT-20 series has integrated self-diagnosis functions and can report status parameters such as zero drift and sensitivity changes in real time. Combined with digital sensors such as RSW-L16S, a predictive maintenance system can be built to achieve:

• Wear trend analysis based on historical data
• Automatic generation of equipment health reports
• Deep data integration with DCS systems

Technical Reliability Verified by Industry Practice

Xi'an Shenghongchuang's column-type force sensors have served leading enterprises such as PetroChina and Wanhua Chemical, with a cumulative deployment of more than 2000 measurement points. Third-party test data show:

• Average trouble-free operating time （MTBF） reaches 58,000 hours
• Meets the OIML R60 C3 accuracy requirements under 98% of operating conditions
• Protection performance has passed the GB/T4208-2017 dustproof and immersion test
