In the field of industrial automation, the performance of the BPL-BPL pressure transmitter directly affects system stability. As an expert in diffused silicon sensor technology, Xi'an Shenghongchuang Instrumentation analyzes the key purchasing points for 2023 for you: from DMU-DMU01 to PT223B-G models, how to choose the most suitable diffused silicon liquid and gas pressure sensor according to medium characteristics, accuracy requirements and budget.

Technical Definition and Core Advantages of Diffused Silicon Sensors

Diffused silicon pressure sensors achieve pressure measurement through the piezoresistive effect of semiconductor silicon materials, and their core advantages lie in high sensitivity（up to 0.1%FS）and long-term stability（＜0.2%/year）. The BPL-BPL series produced by Xi'an Shenghongchuang Instrumentation adopts MEMS technology, maintaining ±0.5% comprehensive accuracy within the range of -40℃~125℃, and is especially suitable for flow control scenarios such as petrochemicals and water treatment. Compared with traditional capacitive sensors, diffused silicon technology improves the pulse pressure response speed of models such as JA-YB202 by 30%, and the HSLYH-HSLYH1 series has passed IP67 protection certification, enabling long-term operation in corrosive media.

Horizontal Comparison of Mainstream Models in the 2023 Market

According to third-party test data, the temperature drift of the PT210B-S model under 80℃ operating conditions is only 0.03%/℃. The YT-YX series adopts a special packaging process, with vibration resistance reaching 5g@10-2000Hz, making it especially suitable for scenarios such as JY-131 that require installation on mobile equipment.

Five Key Technical Parameters for Procurement Decisions

1. Media compatibility：The HSLYH-HSLYH series uses a 316L stainless steel isolation diaphragm, capable of measuring highly corrosive media such as 98% sulfuric acid
2. Long-term stability：After 1000 pressure cycle tests, the zero-point drift of the BPL-BPL pressure transmitter is ＜0.1%FS
3. Temperature impact：The PT223B-G model with a built-in temperature compensation chip has an error of ＜±0.5% within the range of -20~80℃
4. Output signal：DMU-DMU01 provides 4-20mA/RS485 dual output to meet industrial IoT requirements
5. Certification standards：ZRN-ZRN201 has obtained CE, ATEX and SIL2 certifications simultaneously, making it suitable for hazardous areas

Analysis of Typical Customer Cases

After a large water treatment plant used the JA-YB202 pressure transmitter to replace its original product, the following improvements were achieved: 1）measurement error was reduced from 1.2% to 0.3%；2）the maintenance cycle was extended from 3 months to 18 months；3）it was directly connected to the DCS system through the MODBUS protocol. The PT210B-S solution provided by Xi'an Shenghongchuang helped the customer save 32% in spare parts procurement costs.
