The PTS-PTS501 pressure transmitter delivers outstanding performance in industrial gas/liquid pressure monitoring thanks to its high-precision diffused silicon sensor technology. This article provides an in-depth analysis of the core advantages of this model, including stability, anti-interference capability, and typical application scenarios, while also comparing the performance differences among products in the PTS-PTS502/PTS-PTS503 series to help users accurately select a suitable diffused silicon pressure sensing solution.

I. Analysis of Diffused Silicon Sensor Technology

The diffused silicon pressure sensor adopts the piezoresistive effect principle of semiconductor silicon materials, forming a Wheatstone bridge structure on the silicon chip surface through MEMS technology. Compared with traditional strain gauge technology, its sensitivity is increased by more than 30%, and temperature drift can be controlled within the range of ±0.05%FS/℃. The PTS-PTS501 series specially adopts a dual-island structural design, enabling overload capability up to 300MPa while maintaining Class 0.25 overall accuracy. This combination of technologies demonstrates significant advantages in harsh operating conditions such as petrochemical and electric power industries.

III. Detailed Explanation of Typical Application Scenarios

In thermal power unit monitoring systems, the PTS-PTS501, through its 316 stainless steel isolation diaphragm, can withstand long-term impact from 120℃ high-temperature steam, and with 4~20mA two-wire output, enables real-time pressure monitoring of boiler pipelines. Similarly, Domestic General-Purpose Pressure Transmitter PT-307 Liquid and Gas Pressure Sensor also performs excellently in the building automation field, and its stability of ±0.1%FS/year is particularly suitable for the long-term operating requirements of constant-pressure water supply systems.

IV. Procurement and Selection Guide

• For corrosive media, give priority to the PTS-PTS501 + 316 stainless steel configuration
• For cost-effective solutions, consider the PTS-PTS502 with 304 stainless steel
• Pay attention to pressure connection thread standards （M20×1.5/G1/2, etc.）
• Three-wire output is more suitable for 10VDC signal transmission scenarios

V. Common Problem Solutions

When zero-point drift occurs, ±8% range adjustment can be made through the built-in potentiometer. For the signal interference problems commonly seen in BP-IN pressure transmitters, it is recommended to use shielded cables and ensure that the grounding resistance is less than 4Ω. All Shenghongchuang Instrument products support laser marking traceability for convenient quality tracking.
