Validation of Pressure Transmitter Reliability Under Extreme Operating Conditions

In industrial fields such as petrochemicals and electric power energy, pressure transmitters often need to operate stably for long periods in extreme temperature environments. As a flagship product of Xi'an Shenghongchuang Instrumentation Co., Ltd., the CY-H series pressure transmitter adopts advanced diffused silicon sensing technology and is specially designed for operating conditions with a wide temperature range of -40~125℃. This field test mainly verified 5 key performance indicators of this series of products under extreme temperature conditions, providing reliable data reference for industrial users.

1. Accuracy Performance: Stability Testing from Room Temperature to Extreme Values

In the temperature cycling test, the JC-023d model pressure transmitter demonstrated उत्कृष्ट measurement accuracy. The test data show:

• At room temperature 25℃, the accuracy reaches ±0.1%FS (full scale)
• In a low-temperature environment of -40℃, the accuracy remains at ±0.15%FS
• Under high-temperature operating conditions of 125℃, the accuracy fluctuation is only ±0.12%FS

It is particularly worth noting that when the 30.600G-2503-R series products experience abrupt temperature changes (a rate of change of 10℃ per minute), the stability of their output signal still exceeds the requirements of the industry standard GB/T 17614.3-2015. This performance benefits from the temperature compensation algorithm used by the sensor and the specially packaged diffused silicon chip.

2. Service Life: Interpretation of Accelerated Aging Test Data

Through an accelerated test equivalent to 100,000 pressure cycles, the key data of model 30.600G-2503-R-3-8-100-300-2-000 are as follows:

The data indicate that even under harsh operating conditions, the attenuation of core parameters of this series of diffused silicon liquid and gas pressure sensors is controlled within an extremely low range. According to the replacement cycle recommendation for M5256-000002-016BG accessories, the service life in conventional industrial environments can reach more than 8 years.

3. System Compatibility: Verification with Supporting Instruments and Equipment

For common control systems in industrial sites, we tested the compatibility of the CY-H series with the following equipment:

1. A-A11507074 supporting instrument: supports HART 7.0 protocol, with a configuration success rate of 100%
2. M5156-10286X-020BG control equipment: signal response time <2ms
3. PD50-GB10CM20M4M interface module: passed IP67 protection rating verification

Especially in the FST800211G3451-25B system, the linkage test between the pressure transmitter and the flow control equipment showed that under operating conditions with pressure fluctuation of ±5%, the system adjustment response time was shortened by about 18% compared with conventional products.

4. Structural Integrity Under Extreme Temperatures

Through alternating impact tests of -40℃ freezing and 125℃ high temperature (holding each temperature point for 4 hours), the key performance of model PA-21R-120bar-80853.3 is as follows:

• No deformation or cracking of the housing
• Seal leakage rate <1×10⁻⁸ Pa·m³/s
• Electrical connector insertion and extraction force attenuation <3%

This stability comes from a triple-protection design: 316L stainless steel body, fluororubber sealing ring, and special welding process. Compared with similar products, the reduction in mechanical performance attenuation after temperature cycling is more than 40%.

5. Key Points for Identifying Genuine Original Factory Accessories and Original Products

To ensure the reliability of the measurement system, users are advised to note:

• The genuine 30.600G-2503-R-3-8-100-300-1-000 has a laser-engraved anti-counterfeiting code
• The gold plating thickness of the original PD50-GB10CM20M4M interface is ≥1.27μm
• The pressure port of the genuine FST800211G3451-25B adopts a special 30° conical surface seal

Xi'an Shenghongchuang Instrumentation Co., Ltd. provides official website serial number verification services, and all original factory accessories can be verified online through the 16-digit anti-counterfeiting code.

Professional Recommendations and Technical Service Support

Based on the field test data, we recommend the following application solutions for industrial users:

1. For occasions with large temperature fluctuations, give priority to the JC-023d model with temperature compensation
2. For corrosive media environments, it is recommended to use the M5256-000002-016BG special diaphragm
3. For operating conditions with high-frequency pressure fluctuations, the M5156-10286X-020BG damping adjustment module should be configured
