Introduction

As a professional manufacturer in the field of diffused silicon liquid and gas pressure sensors, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides you with a detailed explanation of the 7 major categories of the BAR-ZZAZ series pressure transmitters. This article will offer an in-depth analysis of the technical features of models such as DG1300-BZ-A-2-4/AF and PD50-AB100BM20M4B, helping technical evaluators gain a comprehensive understanding of the principles, selection criteria, and practical application scenarios of diffused silicon sensors.

Technical Overview of Diffused Silicon Pressure Sensors

As a core component in the field of industrial automation, diffused silicon pressure sensors operate based on the piezoresistive effect. When external pressure is applied to the silicon diaphragm, the resistance values of the resistive elements diffused on the diaphragm change, and are converted into an electrical signal output through a Wheatstone bridge. The BAR-ZZAZ series uses monocrystalline silicon material, featuring high sensitivity, good stability, and excellent temperature characteristics. Compared with traditional ceramic or metal strain gauge sensors, diffused silicon technology can achieve high accuracy of 0.1%FS, making it particularly suitable for pressure monitoring in harsh environments such as oil and gas pipelines and chemical reaction vessels for models like DG1300-BZ-A-2-4/AF.

Comparison of Technical Parameters for 7 Major Categories

Key Indicators for Procurement and Selection

When selecting models such as FST800-211G241I, technical evaluators should focus on: 1) process connection methods (such as G1/4", M20×1.5 and other thread standards); 2) explosion-proof certification ratings (such as ATEX, IECEx); 3) long-term stability indicators (usually should be ≤0.1%/year). For the application of the JVPL-JVPL16 pressure transmitter in the food and pharmaceutical industries, it is also necessary to specifically verify the compliance of the 316L stainless steel material and hygienic design.

Analysis of Typical Application Scenarios

The TK-509-10 model delivers outstanding pressure control performance in air compressor systems, and its fast response characteristic (≤1ms) can effectively prevent equipment damage caused by pressure pulsation. Meanwhile, the FST800-501P341G-400B is widely used on petroleum drilling platforms, ensuring reliable operation in extreme environments through its IP68 protection rating and wide operating temperature range of -40~125℃. Practical cases show that offshore drilling platforms using BAR-ZZAZ series transmitters have improved the MTBF (mean time between failures) of their pressure monitoring systems to more than 50,000 hours.

Analysis of Common Technical Misunderstandings

• Misunderstanding 1: Assuming that all diffused silicon sensors are suitable for corrosive media (in fact, it is necessary to confirm whether the diaphragm material is Hastelloy)
• Misunderstanding 2: Ignoring the impact of the installation position on measurement accuracy (vibration sources and heat sources should be avoided)
• Misunderstanding 3: Failing to consider the effect of medium temperature on zero drift (models with temperature compensation need to be selected)
