The NS-P-I7 pressure transmitter, leveraging its diffused silicon Hestman sensor technology, demonstrates outstanding stability in harsh industrial environments. As a core component of flow control equipment, Xi’an Shenghongchuang Instrumentation’s high-precision transmitter series (including models such as CYYB-110 and PT-R) provides reliable pressure monitoring solutions for industrial enterprises. This article will give you a detailed analysis of the practical application performance and technical advantages of this flagship product.

I. Technical Principles and Industry Position of the Diffused Silicon Hestman Sensor

The diffused silicon Hestman pressure sensor adopts semiconductor strain gauge technology, converting pressure signals through the piezoresistive effect of silicon crystals. Compared with traditional ceramic or metal diaphragm sensors, its sensitivity is improved by more than 40%, and temperature drift is controlled within the range of ±0.02%FS/℃. Under the international standard system, this technology complies with the performance evaluation requirements for industrial process control equipment under IEC 60770-1:2010, and is particularly suitable for monitoring extreme operating conditions in industries such as chemicals and energy. As a national high-tech enterprise, Xi’an Shenghongchuang’s NS-P-I7 series has passed ATEX explosion-proof certification and can still maintain a measurement accuracy of ±0.1% within the operating range of -40℃~125℃.

III. Analysis of Typical Industrial Application Scenarios

In a large coal chemical project in Shaanxi, 28 NS-P-I7 pressure transmitters were deployed at key nodes of gasifier pressure pipelines. Faced with frequent pressure fluctuations (0-10MPa cyclic variation) and corrosive media containing solid particles, three years of operating data showed that the zero drift was only 0.08%, far better than the 0.2% indicator required by the contract. In the same project, the PT-R model was applied to the low-temperature methanol washing unit and still maintained a repeatability accuracy of 0.05% under -30℃ operating conditions. This reliability reduced the enterprise’s annual maintenance costs by 37%, avoiding huge losses caused by unplanned shutdowns.

IV. Key Points for Selection and Procurement Decisions

• Range matching: It is recommended to select a model whose maximum working pressure falls between 60%-80% of the range, for example, CYYB-110 is suitable for 0-16MPa operating conditions
• Medium characteristics: Corrosive fluids require derivative models such as DYPT-DYPT212 equipped with titanium diaphragms
• Output signal: 4-20mA+HART protocol is the standard configuration, and the MICO-M series supports the PROFIBUS-PA bus
• Certification requirements: For special scenarios such as offshore platforms, the SRP-580J version with DNV-GL certification should be selected

V. Common Technical Misunderstandings and Answers

Misunderstanding 1: "Diffused silicon sensors are not impact-resistant." In fact, the NS-P-I7 adopts a patented buffer structure. According to actual tests on the MBS-MBS3100 model, it can withstand a mechanical shock of 100g/11ms.Misunderstanding 2: "Domestic sensors have a short service life." Xi’an Shenghongchuang’s accelerated aging tests show that the MTBF of the LED-LED131 series exceeds 150,000 hours under 150% rated pressure, which is comparable to imported brands. When purchasing economical products such as BMP-BMP6010, it is recommended to pay attention to whether the manufacturer provides a complete type test report.
