Under special operating conditions, how can the customized solution for the KS-E-E-C-B02C-M-V diffused silicon pressure sensor precisely meet requirements? As a professional supplier in the field of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides customized services for YM-QP, KS-E-E-C-B04C-M-V and other product series, with full-process assurance from calibration to installation. This article will provide an in-depth analysis of the selection points and working principles of diffused silicon sensors, helping contract executors efficiently solve pressure measurement challenges.

1. Core Advantages and Working Principles of Diffused Silicon Pressure Sensors

Diffused silicon pressure sensors adopt the semiconductor piezoresistive effect principle, achieving high-precision conversion of pressure signals through the Wheatstone bridge on the silicon chip. Taking the KE-240-400BG5M pressure transmitter as an example, its core advantages include:

• Strong temperature stability: error ≤±0.1%FS within the range of -40℃~125℃
• Wide media compatibility: capable of measuring corrosive gases/liquids (customized 316L stainless steel isolation diaphragm required)
• Low long-term drift: annual stability reaches ±0.1%FS (compliant with GB/T 15478-2015 standard)

During the selection process for models such as KS-E-E-Z-B01C-M-V, special attention should be paid to parameters such as measuring range (0-1kPa to 0-100MPa), output signal (4-20mA/0-5V/RS485), and explosion-proof rating (Ex ia IIC T6 Ga).

2. Key Points of Customized Design Under Special Operating Conditions

For extreme environments in industries such as chemicals and energy, the KS-E-E-C-B02C-M-V customized solution needs to consider the following factors:

Taking the application of the 40.4366/000-999-405-502-20-61 pressure transmitter in an LNG storage tank as an example, by adding a PTFE coating and a dual-cavity structural design, the measurement challenge at the ultra-low temperature of -196℃ was successfully resolved.

3. Standardized Process for Calibration and Installation

To ensure the measurement accuracy of the YM-QP pressure transmitter, the following steps must be strictly implemented:

1. Factory calibration: use the FLUKE 729 automatic pressure calibrator to perform 5-point linear calibration (0%/25%/50%/75%/100%FS)
2. On-site installation1/2" NPT male threadHorizontal/vertical pipeline≤0.5mKE-240-400BG5MDN50 flangeStorage tank side wallAvoid vortex area
   

   4. Analysis of Typical Industry Application Cases

   In the petrochemical field, YM-DJYJ series sensors solve specific problems through the following customized solutions:

   • Catalytic cracking unit: adopt KS-E-E-C-B04C-M-V model, adding a sintered metal filter to prevent catalyst blockage
   • Ethylene compressor: customize a dynamic pressure version with a 0-35MPa range and response time <1ms
   • Oil pipeline: integrate HART protocol to achieve remote diagnostics (compliant with API 670 standard)

   After a certain refinery adopted the KS-E-E-C-B02C-M-V customized sensor, the failure rate of the pressure monitoring system decreased by 83%, and annual maintenance costs were reduced by 270,000 yuan.
