This article provides an in-depth test of the YT-YX pressure transmitter, which has attracted widespread attention in the industrial field, with a focus on evaluating the stability performance of its diffused silicon technology under extreme operating conditions. As a professional evaluation in the field of diffused silicon liquid and gas pressure sensors, the report will help technical evaluators understand the actual performance parameters and industry application value of this product.

I. Principles of Diffused Silicon Technology and Industry Background

Diffused silicon pressure sensors measure pressure through the piezoresistive effect of semiconductor silicon materials, with the core being the diffusion-formed Wheatstone bridge on the surface of the silicon chip. Compared with traditional strain gauge technology, diffused silicon sensors feature high sensitivity, good temperature characteristics, and excellent long-term stability. In fields such as petrochemicals and electric power energy, where flow control equipment is used, extreme operating conditions such as media corrosion and mechanical vibration place stringent requirements on sensor stability. Based on 20 years of industry experience, Xi'an Shenghongchuang Instrumentation Co., Ltd. has developed the YT-YX series using third-generation diffused silicon chips, achieving a wide operating temperature range capability of -40℃~125℃ through military-grade packaging technology.

II. Design of the Extreme Environment Test Plan

This test was designed with reference to GB/T 15478-2015 "Performance Test Methods for Pressure Sensors" and includes three sets of comparative experiments: 1) temperature cycle test: 100 rapid temperature changes within the range of -40℃~85℃; 2) mechanical vibration test: random vibration from 10Hz~2000Hz applied according to the IEC 60068-2-6 standard; 3) media compatibility test: the sensor was immersed in corrosive liquids with pH2~12 for 30 consecutive days. All tests simultaneously monitored key parameters such as zero drift and full-scale output error, and were compared horizontally with mainstream market models DMU-DMU01 pressure transmitter and HSLYH-HSLYH pressure transmitter.

IV. Analysis of Key Technical Evaluation Points

1. Temperature compensation algorithm: YT-YX adopts dual-channel temperature sensor real-time correction, which is more accurate than the single-point compensation of the JA-YB202 pressure transmitter; 2. Packaging structure: the 316L stainless steel fully welded housing is superior to the O-ring sealing design of the PT210B-S pressure transmitter; 3. Signal processing: the built-in ASIC chip achieves 0.05%FS nonlinearity compensation, while the ZRN-ZRN201 pressure transmitter still relies on external circuit adjustment. Technical evaluators should pay special attention to the long-term stability index. In scenarios such as desulfurization systems in thermal power plants, the 5-year drift of YT-YX is only 1/3 of that of conventional products.

V. Procurement Decision Support

For different budgets and technical requirements, we recommend: 1) YT-YX as the first choice when the budget is sufficient and the operating conditions are harsh; 2) PT223B-G pressure transmitter for medium budgets; 3) BPL-BPL pressure transmitter for short-term projects.
