In the field of industrial automation, the stability of the DG-DG1300 pressure transmitter directly affects production safety and efficiency. As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides you with an in-depth evaluation of the performance of multiple diffused silicon pressure sensors, helping technical evaluators accurately select the solution best suited to operating conditions.

I. Technical Performance and Market Status of Diffused Silicon Pressure Transmitters

Diffused silicon pressure transmitters have become core components in industrial process control due to their high accuracy and long-term stability. The DG-DG1300 series adopts the single-crystal silicon piezoresistive effect principle, integrating sensitive elements and ASIC signal conditioning circuits through MEMS technology to achieve a measurement accuracy of 0.1%FS. Although similar products currently on the market, such as HP-31C and PMT100, are in a similar price range (approximately 2000-5000 yuan), there are significant differences in overload resistance and temperature compensation technology. According to ISO 9001:2015 certification requirements, high-quality transmitters should have a mechanical life of at least 100,000 pressure cycles, and Xi'an Shenghongchuang's test data shows that the DG-DG1300 can still maintain a stability error of ±0.2% in a high-temperature environment of 80℃.

II. Comparison of Key Parameters and Analysis of Operating Condition Adaptability

For scenarios involving the measurement of high-temperature and high-viscosity media, it is recommended to use it together with Domestic Level Transmitter GY400A Flange-Connected Explosion-Proof Level Sensor. This product uses a 316L stainless steel isolation diaphragm and a hygienic clamp connection, making it particularly suitable for operating conditions in the pharmaceutical and food industries that need to comply with 3-A hygiene standards.

III. Common Misunderstandings in Purchasing Decisions and Solutions

Technical evaluators often fall into two cognitive misunderstandings: first, placing excessive focus on initial procurement costs while ignoring maintenance expenses, for example, although the MB300 is lower in price, it requires calibration every six months; second, failing to consider medium characteristics, such as the need to select the MPT230 model with a Hastelloy diaphragm when measuring hydrofluoric acid. We recommend evaluation through the life cycle cost (LCC) model, and the DG-DG1300's 5-year maintenance-free design can reduce total cost by approximately 27%.

IV. Industry Trends and Directions for Technological Innovation

With the development of IIoT, pressure transmitters are evolving toward intelligence. New-generation products such as SSK207 have integrated LoRa wireless transmission functions, but actual tests show that their sampling rate is 30% lower than that of the DG-DG1300. In the explosion-proof field, intrinsically safe design combined with ATEX certification has become a trend, which forms a complementary solution with the explosion-proof design adopted by GY400A.

V. Why Choose Xi'an Shenghongchuang

As a high-tech enterprise in Xixian New Area, we have three core technology patents for pressure sensors, and all products undergo 72-hour aging tests before leaving the factory. We provide an ultra-long 36-month warranty for the DG-DG1300, far exceeding the industry average. The technical team can provide full-process support from selection to installation, including professional guidance such as drying treatment of the negative pressure chamber during sealed vessel installation.
