As a critical step in the procurement of flow control equipment, the selection of the DG1300-BZ-A-2-0.2 pressure transmitter directly affects system stability. This article addresses the practical needs of contract executors, analyzes the comparison of core parameters of diffused silicon liquid and gas pressure sensors, covers the price, performance differences, and key points for selecting procurement channels for popular models such as P30-10011 and AST-E0117, helping you accurately match project requirements.

I. Analysis of the Core Parameters of Diffused Silicon Pressure Transmitters

In industrial automation control systems, diffused silicon liquid and gas pressure sensors have become a mainstream choice due to their high accuracy and stability. Taking DG1300-BZ-A-2-0.2 as an example, its core parameters include measuring range (0-0.2MPa), output signal (4-20mA), accuracy class (0.5%FS), and other key indicators. Contract executors need to pay special attention: the P30-10011 model uses a 316L stainless steel isolation diaphragm, making it suitable for corrosive media; while AST-E0117 has passed IP67 protection certification, making it more suitable for harsh outdoor environments. Test data from Xi'an Shenghongchuang Instrumentation Co., Ltd. show that under 80℃ high-temperature working conditions, the zero drift of model P-B081023 is only 0.1%/℃.

II. Performance Comparison of Mainstream Models and Selection Guide

The following factors should be prioritized during selection: 1) medium characteristics (for example, P-B074001 is suitable for fluids containing particulates); 2) process connection method (HM27G-2-A1-F1-W2 provides a G1/2" threaded interface); 3) explosion-proof requirements (ZHYL-WQ has passed ATEX certification). It is recommended that contract executors require suppliers to provide EN 837-1 standard test reports to ensure compliance with ASME B40.7 pressure standards.

III. Compliance Verification of Procurement Channels

There are significant price differences (±15%) for models such as P30-10005 on the market, so caution is needed against refurbished products from unauthorized channels. Formal procurement should verify: 1) manufacturer authorization letter (such as Xi'an Shenghongchuang's direct sales qualification); 2) original factory traceability code; 3) metrology institute inspection certificate. Special reminder: the so-called "special price" for the YM-MYJ model on e-commerce platforms may not include CE certification costs, making the final cost even higher instead.
