As a technical evaluator in the field of flow control equipment, are you concerned about the service life of the DG1300-BZ-A-2-35 pressure transmitter? Based on 5 years of measured data from Xi'an Shenghongchuang Instrumentation Co., Ltd., this article provides an in-depth analysis of the service life performance of this liquid and gas pressure sensor using diffused silicon technology, offering you a professional and reliable basis for evaluation.

I. Technical Principle and Industry Positioning of Diffused Silicon Pressure Sensors

The DG1300-BZ-A-2-35 pressure transmitter adopts internationally mainstream diffused silicon sensing technology, and its core principle is to realize pressure signal conversion through the piezoresistive effect of semiconductor silicon materials. Compared with traditional strain gauge sensors, diffused silicon technology features higher sensitivity（typical value 0.1%FS）and better long-term stability. As a national high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd. has passed ISO9001 quality management system certification. Measured data under harsh working conditions such as petrochemical and power energy industries show that the average mean time between failures（MTBF）of this model reaches 58,000 hours.

II. Comparative Analysis of Key Measured Data Over 5 Years

We conducted tracking monitoring on DG1300-BZ-A-2-35/FC/GZ pressure transmitters deployed at 36 industrial sites from 2018-2023, and found the following changes in key indicators:

It is particularly worth noting that for the DW803-10MPa-C-1-A-Z-0-3 series product operating in the 10MPa range segment, due to the use of a reinforced 316L stainless steel isolation diaphragm, its mechanical fatigue index is better than the requirements of the industry standard GB/T15478-2015.

III. Three Technical Solutions for Extending Service Life

Based on comparative studies of multiple models such as MPM480E22B1C1A, we have summarized the following key measures for extending the service life of diffused silicon pressure sensors:

• Media compatibility optimization: For corrosive media, it is recommended to choose the GPD-GPD25 pressure transmitter with a Hastelloy diaphragm, whose pH tolerance range can reach 0-14
• Overload protection design: Through the built-in mechanical limit structure, the sudden overload tolerance of models such as 26.600G-X102-R-1-8-100-R40-1-000 is increased to 3 times the nominal value
• Temperature compensation algorithm: Using the third-generation ASIC chip, the temperature drift error is controlled within ±0.5%FS at -40℃~125℃

IV. Selection Recommendations for Technical Evaluators

Select the sensor type according to fluid characteristics: for high-viscosity media, it is recommended to choose the special DG1300-BZ-A-2-35 model with a conical pressure guide hole; in pipelines where water hammer effects exist, the buffering structure of MPM480E22B1C1A can effectively reduce pressure impact damage. The customized services provided by Xi'an Shenghongchuang can meet the needs of different measurement scenarios, including special qualifications such as explosion-proof certification（Ex ia IIC T6）and marine certification（CCS）.
