This article provides a professional field test of the DG1300-BZ-A-2-1 pressure transmitter, focusing on the performance of its diffused silicon sensor under extreme environments. As a core product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this model offers significant advantages in liquid and gas pressure monitoring. We will use measured data to address your concerns about the reliability of diffused silicon sensors.

I. Technical Principles and Industry Positioning of Diffused Silicon Sensors

Diffused silicon pressure sensors convert pressure signals through the piezoresistive effect of semiconductor silicon materials. Their core advantages lie in temperature stability and long-term drift control. In industrial-grade flow control equipment, the DG1300 series adopts third-generation diffused silicon chips. Through ion implantation technology, the Wheatstone bridge is directly integrated onto the silicon diaphragm. Compared with traditional strain gauge technology, its sensitivity is improved by more than 40%. As a national high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd. has this product line certified under the ISO 9001:2015 quality management system and compliant with the GB/T 15478-2015 national standard for pressure sensors.

II. Comparative Analysis of Measured Data in Extreme Environments

Within the temperature range of -40℃~125℃, we conducted comparative tests between the DG1300-BZ-A-2-1 and the similar HM20G-1-A1-F1-W2 pressure transmitters:

III. Typical Application Scenarios and Selection Recommendations

In the petrochemical field, the DG1300-BZ-B-2-1.6 pressure transmitter has been successfully applied in cracking furnace pressure monitoring systems, and its hydrogen sulfide corrosion resistance has been certified by NACE MR0175. Regarding the procurement cost concerns of commercial evaluators, this product series adopts a modular design and supports multiple interface standards such as PT124B-212-5MPa-ZG1/2. Compared with the BFY-1103 pressure transmitter, it can reduce spare parts inventory costs by 20%. Technical evaluators should focus on the turndown ratio (up to 10:1) and media compatibility (316L stainless steel isolation diaphragm).

IV. Common Technical Misunderstandings and Solutions

Misunderstanding 1: Believing that all diffused silicon sensors perform the same. Actual tests show that the temperature compensation algorithm used in the DG1300-PJ-1-2-40/CJ/GK/GZ can reduce full-temperature-range errors by 60%. Misunderstanding 2: Ignoring the impact of installation position. Our cases show that in HT-PD pressure transmitter installations, using a capillary tube extension method can effectively prevent direct contact with high-temperature media. To address the signal interference issue of the FST800-501 pressure transmitter, it is recommended to use shielded cables and maintain grounding resistance ＜4Ω.
