Xi'an Shenghongchuang Instrument Co., Ltd., as a professional manufacturer of diffused silicon Hesmann pressure sensors, has gained market recognition for its MSP-MSP5100 pressure transmitter with outstanding performance. This article provides an in-depth analysis of the company's technical strength, examines the development trends of diffused silicon sensing technology, and offers authoritative selection references for technical evaluation personnel. From the EET-1040 to the full PT503 series, we reveal the core technological breakthroughs behind domestically produced high-precision pressure measurement.

Technical Definition and Core Advantages of Diffused Silicon Hesmann Pressure Sensors

Diffused silicon technology forms a piezoresistive bridge on the surface of a silicon chip through semiconductor processing. When pressure is applied, resistance changes are generated and a standard signal is output through signal conditioning circuitry. Xi'an Shenghongchuang's MSP-MSP5100 series adopts third-generation Hesmann interface technology, achieving an accuracy grade of ±0.1%FS, far exceeding the industry average of ±0.5%FS for traditional ceramic capacitive sensors. Its core advantages are reflected in:

• Temperature compensation algorithm: polynomial fitting compensation technology is adopted, with a temperature drift coefficient ≤±0.01%FS/℃
• Media compatibility: the 316L stainless steel isolation diaphragm can withstand highly corrosive media and has passed NACE MR0175 certification
• Long-term stability: based on 100,000 pressure cycle test data, the annual drift is <0.1%FS

Analysis of Technical Requirements in the Flow Control Equipment Industry

In flow control scenarios such as petrochemical and water treatment, the performance of pressure transmitters directly affects system reliability. Our field test data for models such as EET-1040 and CYB-I show:

Especially in the field of natural gas metering, the PT-PT503 model has passed GB/T 18603-2014 standard certification, and its 0.05 accuracy grade can meet trade settlement requirements.

Selection Guide for Technical Evaluation Personnel

For different application scenarios, we recommend:

1. High-temperature operating conditions: choose the P-P700 series, with a built-in temperature sensor for real-time compensation
2. Cost-sensitive projects: the EA-EA218 series reduces procurement costs by 30% while maintaining 0.2% accuracy
3. Explosion-proof requirements: the KSYGX-KSYGX series has obtained both ATEX and IECEx certifications

It is worth noting that the JY-JY132 model adopts a patented overload protection structure, which can effectively prevent sensor damage under pressure shock conditions.

Future Development Trends of Diffused Silicon Technology

According to the latest research in IEEE Sensors Journal, the next generation of pressure sensors will show three major breakthroughs:

• MEMS and ASIC integration: MSP-MSP5100 has already achieved co-packaging of the signal conditioning chip and sensing element
• Wireless transmission: intelligent transmitters supporting the LoRaWAN protocol are currently in the testing stage
• Self-diagnostic function: predicting remaining service life based on machine learning algorithms

Xi'an Shenghongchuang is developing its fourth-generation products by integrating these technologies, and prototype launch is expected in 2024.
