In the field of industrial automation, the performance stability of the CYB-I pressure transmitter has attracted significant attention. This article provides an in-depth analysis of the core performance of this diffused silicon pressure sensor for liquids and gases through 3 sets of measured data. As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. will use experimental data to show you why CYB-I can become a benchmark product in the industry.

I. Temperature Drift Test: Stability Performance in Extreme Environments from -20℃~65℃

In harsh operating conditions such as chemical metallurgy, petroleum, and natural gas, temperature changes have a particularly significant impact on sensor accuracy. We simulated a temperature gradient of -20℃~65℃ (in line with the operating temperature standards of similar products such as domestic weighing sensor CKY-105 spoke-type large-range experimental force sensor circular pressure sensor) and conducted continuous monitoring of the CYB-I for 72 hours. The data shows:

• Zero-point temperature effect: ±0.025%FS/10℃, better than the industry average level of ±0.05%
• Output stability: fluctuation within the full scale range ≤0.03%, meeting aerospace-grade application requirements
• Thermal recovery performance: recovers baseline accuracy within 3 minutes after a sudden temperature change, 40% faster than traditional diffused silicon sensors

This performance is closely related to the alloy steel sensor housing developed by Xi'an Shenghongchuang, whose thermal expansion coefficient perfectly matches the silicon chip, thereby structurally suppressing temperature stress.

II. Long-Term Stability Test: Accuracy Attenuation After 10000 Pressure Cycles

For scenarios requiring long-term monitoring, such as water conservancy, electric power, and municipal management, we simulated a pressure cycle test equivalent to 10 years of service intensity in the laboratory:

This degree of attenuation is equivalent to an annual accuracy loss of only 0.0003%. Compared with similar products such as the PMP-PMP4000 pressure transmitter (annual attenuation 0.0012%), CYB-I has a clear advantage in long-term stability. The core lies in the use of military-grade stainless steel diaphragms and laser welding technology to ensure no creep deformation of the elastic body.

III. Media Compatibility Test: Reliability Verification in Corrosive Gases/Liquids

In special industries such as environmental protection and pharmaceuticals, sensors need to come into contact with acidic and alkaline media. We immersed the CYB-I in solutions with pH2~12 and introduced mixed gas containing H2S:

1. Sealing performance: under IP68 protection rating, insulation resistance remains ≥5000MΩ after 500 hours of immersion
2. Corrosion resistance: 316L stainless steel wetted parts showed no pitting after 200 hours in the salt spray test
3. Output consistency: sensitivity deviation in different media ≤0.1mV/V, better than competing products such as AOB-131

This is inseparable from the company's full-process quality control system established with reference to ISO 9001, under which strict standards are implemented from raw material screening to aging tests.

IV. Industry Solutions: How to Choose a Matching Pressure Transmitter

Based on the measured data, we recommend the following selection strategies for different scenarios:

1. High-temperature and high-pressure scenarios (such as thermal paper making)

Give priority to the enhanced version of CYB-I, which adopts a special heat dissipation design and can maintain accuracy under instantaneous high temperatures of 150℃, similar to the application solution of domestic weighing sensor CKY-105 in the steel industry.

2. Corrosive environments (such as chemical metallurgy)

It is recommended to configure a Hastelloy diaphragm, combined with Shenghongchuang's patented media isolation technology, to cope with strongly corrosive media such as 98% concentrated sulfuric acid.

3. Dynamic pressure measurement (such as construction machinery)

Choose a fast-response model with a response time of ≤1ms, whose performance parameters are close to the military standard of the EET-1040 pressure transmitter.

V. Conclusion: A Professional Choice Proven by Data

As one of the few domestic diffused silicon pressure transmitters certified to SIL2, CYB-I has demonstrated benchmark-level performance in all three core tests.
