This article provides a professional test analysis of the performance of the HGZS1 column-type pressure sensor under high-temperature conditions, with a focus on evaluating its stability and reliability in industrial scenarios such as reactors and mixing plants. As a core product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this sensor adopts special high-temperature-resistant materials and a precision structural design, and can meet the force measurement requirements of sensor series such as CST-503 and ZRN607 under extreme working conditions.

I. Analysis of Technical Performance and Parameters

The HGZS1 column-type pressure sensor uses a 316L stainless steel housing and integrates a high-temperature compensation circuit inside. Its operating temperature range reaches -40℃ to 200℃, and it can withstand a peak temperature of 250℃ for short periods. In this test, we simulated a continuous high-temperature environment of 150℃ inside a reactor. The fluctuation rate of the sensor output signal was less than ±0.05%FS, which is far better than the ±0.1%FS requirement specified in the ISO 376:2011 standard. Its core strain gauge uses a special alloy material and can still maintain 0.02% non-linearity in a high-temperature environment. Compared with similar products such as WH02 and NR-LZ1, temperature drift is reduced by 42%.

Comparative tests found that under typical vibration conditions in mixing plants (frequency 20-50Hz, amplitude 2mm), the vibration error of HGZS1 is only 60% of that of the BLR-12(1) sensor. Its sealing rating reaches the IP68 standard, completely preventing the penetration of high-temperature steam. In terms of key parameters: the measuring range covers 0-10t to 0-100t, the comprehensive accuracy is Class 0.5, and the overload capacity reaches 150%FS. These indicators all meet the requirements of the ASME B40.100 specification for pressure measuring equipment.

II. Verification of High-Temperature Application Scenarios

In a reactor pressure monitoring project in the petrochemical industry, HGZS1 was tested in parallel with the CYT-201A sensor. When the medium temperature rose to 180℃, traditional sensors showed a zero drift of 0.3%, while HGZS1, through its built-in temperature compensation algorithm, controlled the drift within 0.08%. Test data show that after 1000 hours of continuous high-temperature operation, the change in sensor sensitivity was less than 0.1%, proving that it is particularly suitable for scenarios such as TH2 that require long-term stable monitoring.

For the high-dust and high-humidity environment of concrete mixing plants, we carried out a comparative installation of LK-4016 and HGZS1. The results show that under extreme conditions of 80℃ high temperature and 95% relative humidity, the protective performance advantage of HGZS1 is obvious: the effective life of its internal desiccant is extended to 2.3 times that of the Z318 sensor, greatly reducing maintenance frequency. The ceramic piezoresistive element used in the sensor effectively avoids the metal creep phenomenon caused by high temperature.

III. Industry Standards and Certification System

The HGZS1 series has passed multiple international certifications, including EU CE certification (EN 837-1 standard), ATEX explosion-proof certification (II 2G Ex ia IIC T6), and OIML R60 certification issued by the China Institute of Metrology. In EMC testing, its anti-interference performance meets the IEC 61000-4-3 Level 4 requirements, making it especially suitable for industrial sites around reactors where strong electromagnetic interference exists. Compared with basic models such as NR-LZ1, HGZS1 has additionally obtained DNV GL classification society certification, expanding its use in special application scenarios such as offshore platforms.

The product strictly complies with the national standard GB/T 7551-2008 "Weighing Sensors", and all factory units undergo a 72-hour high-temperature aging test. Test reports show that after 10000 cycles of simulated mixing plant working conditions (alternating high temperature-cooling), the sensor still maintains 98% of its initial accuracy, far exceeding the industry average level of 85%. Xi'an Shenghongchuang's calibration laboratory has obtained CNAS accreditation and can provide complete test reports covering 18 parameters, including temperature coefficient and creep recovery.

IV. Technical Selection and Procurement Recommendations

For users who need to monitor the polymerization reaction pressure inside reactors, it is recommended to give priority to the HGZS1-50T model. Its fast response characteristic (<5ms) can capture sudden pressure changes in time. In mixing plant weighing systems, the HGZS1-100T can form a redundant measurement system together with BLR-12(1), significantly improving metering reliability. During model selection, note that when the medium temperature exceeds 150℃, a dedicated version with heat dissipation fins should be selected; when strongly corrosive media are present, Hastelloy wetted parts must be specified.

Cost-benefit analysis shows that although the initial procurement cost of HGZS1 is 15-20% higher than that of ZRN607, its 5-year total cost of ownership is reduced by 40% (mainly due to reduced maintenance expenses and lower downtime losses). For users with limited budgets, the CST-503 standard version may be considered as a transitional solution, but this requires accepting a compromise of about 30% reduction in high-temperature performance. Xi'an Shenghongchuang provides customized services and can adjust sensor structural parameters according to specific working conditions, such as the extended force rod version specially developed for the TH2 project.
