The YM-YSBYJ pressure transmitter adopts advanced diffused silicon sensor technology to accurately measure liquid and gas pressure. This article provides a detailed analysis of its working principle and answers common questions such as installation and maintenance, helping business evaluators gain a comprehensive understanding of the technical features and advantages of this high-performance pressure transmitter.

In-depth Analysis of the Technical Principles of Diffused Silicon Sensor Technology

As the core component of the YM-YSBYJ pressure transmitter, the diffused silicon pressure sensor operates based on the piezoresistive effect. When external pressure acts on the silicon diaphragm, the diaphragm undergoes slight deformation, causing a change in the resistance value of the Wheatstone bridge embedded in the silicon crystal. This change is converted into a standard electrical signal (such as 4-20mA or 0-10V) through precision circuitry, ultimately enabling accurate measurement of pressure values. Compared with traditional strain gauge technology, diffused silicon sensors offer three core advantages: high sensitivity (typical value up to 2mV/V), excellent long-term stability (annual drift＜0.1%FS), and superior temperature characteristics (built-in temperature compensation range -40℃~125℃).

Professional Installation and Maintenance Guide

For the installation of YM-JL series pressure transmitters, special attention should be paid to the following points: first, ensure that the installation location is away from vibration sources and strong electromagnetic fields, and G1/2" or NPT1/2" threads are recommended for process connections. For YM-GJ models with remote signal transmission, the signal cable should use shielded twisted pair and be routed in a separate cable tray. In terms of routine maintenance, the WS-WS101 model is recommended to undergo zero-point calibration every 6 months, while QBE-QBE2002 models with alarm control require monthly testing of the alarm function. All diffused silicon sensor products are provided with a one-year warranty service, but it should be noted that diaphragm damage caused by medium crystallization or corrosion is not covered by the warranty.

Industry Application Scenarios and Selection Recommendations

In the petrochemical field, explosion-proof transmitters of the YM-YYJ specification can perfectly meet API 670 standard requirements; for the water conservancy industry, the KS-E-E-C-B01M-M-V model is more recommended, and its IP68 protection rating can handle long-term operation at a depth of 10 meters underwater. For the food and pharmaceutical industries, we recommend selecting the TEYB-KO-KA model with a sanitary flange connection, with all wetted parts made of 316L stainless steel and certified to 3A. When selecting a model, business evaluators should focus on key parameters such as medium characteristics (corrosiveness/viscosity), process temperature range, and whether the HART communication protocol is required.
