As a core component of industrial automation control, the key parameters of the diffused silicon sensor in the JPB-CNM pressure transmitter directly affect measurement accuracy. This article provides an in-depth analysis of the technical specifications of pressure transmitters such as DG1300-BZ-A-2-40/CJ/AM/FZ, helping technical evaluators master the selection points and working principles of diffused silicon liquid and gas pressure sensors, and improve the measurement reliability of flow control systems.

Technical Principles and Industry Applications of Diffused Silicon Sensors

Diffused silicon pressure sensors use the piezoresistive effect of semiconductor silicon materials to achieve pressure measurement, with the core being the formation of a Wheatstone bridge on the silicon diaphragm through ion implantation technology. When external pressure acts on the silicon diaphragm, the bridge resistance changes and outputs a millivolt-level signal. Compared with traditional strain gauge technology, diffused silicon sensors in models such as DG1300-BZ-A-2-2.5/AA/SZWZH offer significant advantages including high sensitivity (typical value 2mV/V), low temperature drift (±0.02%FS/℃), and good long-term stability (±0.1%FS/year). In the petrochemical field, the PBM4-13.B29R.A115.2663 pressure transmitter can accurately measure the pressure of corrosive media within pipelines from 0-40MPa; while in the food and pharmaceutical industries, the FDA-compliant PMP131-C1A2L16 model is widely used in process control for sterile environments.

Analysis of Five Key Parameters Affecting Measurement Accuracy

Selection Guide and Technical Evaluation Points

For different application scenarios, technical evaluators need to focus on the following dimensions: the measurement range should cover 1.5 times the working pressure (for example, the PA-21R-16 model provides a 0-16MPa range); the process connection must match on-site interface standards (G1/2", NPT1/2, etc.); and the electrical interface should take explosion-proof requirements into account (the MTPFU-MTPFU series is ATEX certified). For food-grade applications, it is recommended to choose the customized PBM4-13.B38R.A115.2663 model with a PTFE isolation diaphragm; while for high-precision flow control applications, the DG1300-BZ-A-2-40/CJ/AM/FZ transmitter equipped with a 0.075 accuracy class sensor can meet trade settlement requirements.

Typical Solutions and Maintenance Recommendations

• Zero drift issue: Perform online calibration regularly (recommended every 6 months), and use a HART communicator to adjust the Zero Trim parameter of the JPB-CNM
• Signal interference handling: Configure a shielded cable for the PT201H-G5000M, and keep a distance of more than 30cm from power lines
• Diaphragm clogging prevention: In wastewater treatment applications, equip the HM20-1-A1-F1-W2-T with a self-cleaning diaphragm structure
• Winter anti-freezing measures: Install a heat tracing jacket for the PMP131-C1A2L16 to maintain the medium temperature above 5℃
