Having trouble selecting the DG1300-BZ-A-2-4/AF pressure transmitter? As a professional diffused silicon sensor manufacturer, Xi'an Shenghongchuang Instrumentation explains 5 core indicators for you. From PD50-AB100BM20M4B to the FST800 series, we will provide an in-depth analysis of the principles, application scenarios, and purchasing points of diffused silicon sensors to help technical evaluators accurately match industrial requirements.

I. Analysis of Core Indicators of Diffused Silicon Sensors

In the field of flow control equipment, the performance of diffused silicon pressure transmitters is directly related to system stability. Taking DG1300-BZ-A-2-4/AF as an example, its core evaluation indicators include measurement accuracy (±0.1%FS and above), long-term stability (<0.2%/year), media compatibility (316L stainless steel isolation diaphragm), temperature influence coefficient (±0.02%/℃), and protection rating (IP67/IP68). Xi'an Shenghongchuang Instrumentation adopts MEMS silicon piezoresistive technology and ensures through the ISO9001 quality management system that every FST800-501P341G series product meets industrial-grade anti-interference standards.

II. Technical Comparison: Differences Between Diffused Silicon and Other Sensing Principles

Compared with traditional capacitive or ceramic piezoresistive sensors, diffused silicon technology performs outstandingly in dynamic response (<1ms) and overload capacity (200%FS). Taking the PD50-AB100BM20M4B model as an example, it uses a temperature compensation algorithm to maintain ±0.5% accuracy within the range of -40℃~125℃, while similar ceramic sensors may have an error of up to ±2% in low-temperature environments. The characteristics of different technical routes can be visually compared through the table below:

III. Typical Application Scenarios and Selection Points

Different media characteristics require matching corresponding models. For example, FST800-501P341G-100B is suitable for corrosive liquid measurement, and its Hastelloy diaphragm can resist acid and alkali corrosion; while the JYB series is more suitable for gas pressure monitoring, with a built-in EMC protection circuit that can suppress inverter interference. Technical evaluators should focus on:

• Chemical compatibility of the medium (refer to ASTM G31 standard)
• Process connection method (such as G1/4", M20×1.5)
• Output signal type (4-20mA/RS485/HART protocol)
• Explosion-proof certification requirements (such as Ex ia IIC T6)

IV. Procurement Pitfall Avoidance Guide and FAQ

Q: How to identify a genuine diffused silicon sensor?
A: Check three points: ① the metrology verification certificate provided by the original manufacturer ② whether the chip laser code is consistent with the packaging ③ verify the serial number through the manufacturer's official website. All FST800-211G241I pressure transmitters from Xi'an Shenghongchuang support online authenticity verification.

Q: Why does the TK-509-10 pressure transmitter experience zero drift?
A: It is usually caused by sudden temperature changes or mechanical overload. It is recommended to choose the JVPL-JVPL16 model with automatic temperature compensation, which uses a dual Wheatstone bridge design to reduce temperature drift by 60%.
