In industrial automation control systems, the selection of YM-YYJ pressure transmitters directly affects production efficiency and equipment safety. This article comprehensively analyzes the specification parameters of diffused silicon liquid and gas pressure sensors, helping commercial evaluators choose the model best suited to industrial scenarios based on key factors such as medium characteristics, measurement range, and installation environment.

I. Technical Principle and Core Advantages of Diffused Silicon Pressure Transmitters

The YM-YYJ series pressure transmitters adopt diffused silicon piezoresistive sensing technology, converting pressure signals through resistance changes in semiconductor strain gauges. Compared with traditional capacitive sensors, their response speed can reach 0.1ms, with a long-term stability error of ≤±0.1%FS/year, making them particularly suitable for rapid pressure monitoring in fields such as petrochemicals and power energy. Xi'an Shenghongchuang Instrumentation Co., Ltd.'s patented sealing structure design gives the products an IP67 protection rating, enabling them to handle extreme working conditions from -40℃~85℃.

II. Comparative Analysis of Key Specification Parameters

Commercial evaluation should focus on the following parameters: measurement range (0-1kPa to 0-60MPa optional), accuracy class (0.2 class/0.5 class), and output signal (4-20mA/RS485/HART protocol). Taking the YM-GJ model with remote transmission signal as an example, it uses a 316L stainless steel isolation diaphragm, making it compatible with corrosive media measurement; while the compact structure of the TEYB-KO-KA model (dimensions shown in the official website CAD drawings) is suitable for space-constrained scenarios. We recommend confirming material selection through a media compatibility test report (providing NACE MR0175 standard certification).

III. Selection Guide for Industrial Scenarios

For different application scenarios, we provide the following specific recommendations: 1) For hydraulic systems, prioritize the YM-JL model, which has shock resistance up to 100g; 2) For the food and pharmaceutical industries, the WS-WS101 model is recommended, featuring a hygienic design compliant with FDA certification; 3) For explosion-proof areas, the KS-E-E-C-B04U-M-V model with intrinsic safety certification should be selected. During installation, note that the process connection must match the ANSI/ASME B16.5 flange standard, and the cable entry must be waterproofed (refer to Chapter 3 of the YM-JL installation manual).

IV. Common Misconceptions and Maintenance Points

Customers often overlook the issue of medium crystallization (such as in urea production conditions), and it is recommended to choose a model with a diaphragm self-cleaning function. During maintenance, zero drift should be checked regularly (online calibration can be performed using our HART handheld communicator), and the pressure port should be cleaned quarterly. Xi'an Shenghongchuang provides an ultra-long 24-month warranty (including free technical training) and also supports sensor lifecycle management services.

V. Why Choose Shenghongchuang Instrumentation
