When selecting the JY-131 pressure transmitter, how should you evaluate the cost performance of a diffused silicon sensor? This article is tailored to the needs of technical evaluators, providing an in-depth analysis of quotation differences among models such as PT210B-S and PT223B-G, helping you choose the high-precision solution best suited for industrial gas/liquid pressure monitoring from authorized suppliers such as DMU-DMU01 and HSLYH-HSLYH.

Core value and technical definition of diffused silicon pressure transmitters

As the core component of the JY-131 pressure transmitter, the diffused silicon sensor operates based on the semiconductor piezoresistive effect. When external pressure acts on the silicon diaphragm, the millivolt-level signal output by the Wheatstone bridge is converted by the amplification circuit into a standard 4-20mA output. Compared with traditional ceramic capacitive sensors, diffused silicon technology offers high accuracy of ±0.1%FS and long-term stability of 0.01%, making it especially suitable for demanding flow control applications such as petrochemical processing and natural gas transmission. Xi'an Shenghongchuang Instrumentation Co., Ltd. uses imported German silicon wafers, and the HSLYH-HSLYH1 series sensors manufactured through MEMS technology can still maintain ±0.25% accuracy within the operating range of -40~125℃, and this performance parameter directly determines the equipment's life-cycle cost.

Mainstream model quotation comparison and technical parameter analysis

From the comparison data, it can be seen that although the PT223B-G model has a higher unit price, it adopts a 316L stainless steel isolation diaphragm and laser welding technology, which can reduce maintenance costs by 60% in high-pressure scenarios such as natural gas compressors. The DMU-DMU01 pressure transmitter, on the other hand, is more suitable for low-pressure scenarios such as ventilation systems. Its economical design complies with the ISO 9001:2015 standard and is an ideal choice for projects with limited budgets.

Five major technical evaluation dimensions for procurement decisions

1. Media compatibility: For corrosive media, choose the HSLYH-HSLYH series version with a Hastelloy diaphragm
2. Temperature compensation range: The JA-YB202 model has a built-in intelligent compensation algorithm for -30~80℃
3. Explosion-proof certification level: ZRN-ZRN201 has passed ATEX II 2G Ex d IIC T6 certification
4. Output signal type: The YT-YX series supports HART protocol digital communication
5. Long-term stability indicator: The annual drift of PT210B-S is ≤0.1%FS

Industry application scenarios and selection misconceptions

In aeration system control at wastewater treatment plants, customers often mistakenly select the standard PT210B-S, resulting in diaphragm corrosion. In fact, the PTFE-coated version of the HSLYH-HSLYH1 pressure transmitter should be selected. Although the unit price increases by 15%, the service life can be extended by 3 times. Another typical case is pressure monitoring of LNG storage tanks, where the low-temperature-specific model of PT223B-G must be used, and its low-temperature adaptability at -196℃ has passed the GB/T 25480-2010 test.
