Under high-temperature operating conditions, the stability of the JLHT load cell directly affects the operating efficiency of industrial equipment such as reactors and mixing plants. Based on measured data, this report provides a detailed analysis of the performance of this column-type pressure sensor in extreme environments, offering key equipment selection references for business decision-makers.

I. Challenges of High-Temperature Environments to Sensor Performance

In industrial scenarios, equipment such as reactors and mixing plants is often exposed to continuous high-temperature environments above 80℃. Traditional load cells are prone to issues such as zero drift and reduced sensitivity under high temperatures, resulting in measurement errors as high as 5%-8%. The JLHT series developed by Xi'an Shenghongchuang Instrumentation Co., Ltd. adopts special alloy materials and vacuum sealing technology, has passed ISO 9001:2015 certification, and is specifically designed for extreme operating conditions.

III. Comparison of Key Parameters with Competing Products

Compared with the mainstream market models RSZ07 and CPH-3 sensors, JLHT shows significant temperature compensation performance in a 150℃ environment:

• Zero temperature coefficient: JLHT（0.002%FS/℃）is superior to RSZ07（0.005%FS/℃）
• Sensitivity temperature coefficient: JLHT（0.0015%FS/℃）is only 50% of CPH-3（0.003%FS/℃）
• Insulation resistance: JLHT maintains above 5000MΩ, while competing products generally decline to 2000MΩ

IV. Verification in Typical Application Scenarios

In a reactor project of a chemical enterprise in Shaanxi, after 8 JLHT sensors operated continuously for 6 months:

1. The cumulative error was controlled within 0.1%FS
2. The failure rate was 0, reducing downtime losses by 370,000 yuan compared with the original SM11 sensors
3. Passed OIML R60 international recommendation certification

V. Recommendations for Selection Decision-Making

Business decision-makers should focus on:

• Material certification: whether it has passed the ASTM E228 high-temperature tensile test
• Compensation range: -40℃~200℃ is the baseline for the chemical industry
• Protection rating: IP68 is a necessary requirement for mixing plant scenarios
