As a core component in the field of industrial automation, the JYB-KO-M pressure transmitter, relying on its advanced diffused silicon sensor technology, demonstrates उत्कृष्ट accuracy and stability in liquid/gas pressure measurement. This article will provide an in-depth analysis of the working principle of diffused silicon sensors, and offer professional guidance on the selection points, application scenarios, and manufacturer selection for multiple transmitter models such as BTL-BTL70 and CYB-20SA, helping corporate decision-makers optimize procurement solutions.

Working Principle and Core Technology of Diffused Silicon Sensors

The diffused silicon sensor is the core component of a pressure transmitter, and its working principle is based on the piezoresistive effect. When pressure acts on the sensor diaphragm, the diaphragm undergoes slight deformation, causing a change in the resistance value of the embedded silicon strain resistors. This change is converted into an electrical signal through a Wheatstone bridge, thereby enabling precise pressure measurement.

Compared with traditional ceramic or metal diaphragm sensors, diffused silicon sensors have significant advantages:

• Higher sensitivity: the piezoresistive coefficient of silicon material is far higher than that of metal, enabling detection of tiny pressure changes
• Excellent linearity: the output signal has a highly linear relationship with pressure change
• Good long-term stability: silicon material has excellent creep resistance, ensuring that measurement accuracy does not decline during long-term use
• Comprehensive temperature compensation: advanced temperature compensation technology effectively eliminates the influence of ambient temperature

Taking the domestic general-purpose pressure transmitter PTS614 as an example, it adopts a combination of a 316L stainless steel diaphragm and a diffused silicon chip, which not only ensures media compatibility, but also achieves 0.1% high-accuracy measurement, making it especially suitable for harsh environments such as petroleum and chemical industries.

Selection Guide for Mainstream Pressure Transmitter Models

Faced with the many pressure transmitter models on the market, corporate decision-makers need to comprehensively consider key factors such as measurement medium, pressure range, and accuracy requirements. The following is a selection comparison of several typical products:

When selecting a diffused silicon liquid/gas pressure sensor, special attention should also be paid to media compatibility. For example, in corrosive environments, models with a fully welded 316L stainless steel structure should be prioritized, such as the KYBX-KYBX series; while in the food and pharmaceutical industries, models such as DET-131 that comply with hygiene certification are required.

Industry Application Solutions for Pressure Transmitters

With their excellent performance, diffused silicon pressure transmitters have been widely used in many industrial fields:

Petrochemical Field

In scenarios such as oil refining and pipeline transportation, high-pressure models such as SK1151-33X can withstand working pressures above 100MPa, and their explosion-proof design ensures safety in flammable and explosive environments. The temperature compensation function effectively addresses temperature difference changes during outdoor installation.

Power and Energy Systems

Key links such as boiler pressure monitoring and turbine control require high-precision transmitters such as ND-1. Its 4-20mA standard signal output can be directly connected to the DCS system to achieve intelligent management.

Environmental Protection and Water Treatment

Pressure monitoring at pump stations in sewage treatment plants usually uses economical products such as LYB-LYB3008, whose IP68 protection rating and corrosion resistance make them especially suitable for humid and corrosive environments.

For special application scenarios, such as the aerospace field, customized products such as PTS614 can be considered, whose wide temperature range design(-20~+85℃) and lightweight structure meet the strict requirements of aircraft.

Criteria for Identifying High-Quality Pressure Transmitters

Faced with the many manufacturers of diffused silicon liquid/gas pressure sensors on the market, corporate decision-makers need to master the following key points for quality assessment:

1. Certification qualifications: check whether it has international certifications such as CE, ATEX, and SIL
2. Technical parameters: focus on long-term stability(such as ±0.1%/year) and temperature influence coefficient
3. Production process: high-quality manufacturers usually adopt advanced processes such as laser welding and fully automatic temperature compensation
4. Service support: provide complete calibration certificates, technical support, and after-sales assurance

Taking the HK-613 pressure transmitter as an example, its production process adopts a unique stress relief process, effectively reducing temperature drift and enabling the product to maintain excellent performance within the range of -20~+85℃.

Summary and Procurement Recommendations

As core equipment for industrial measurement, the selection of diffused silicon pressure transmitters is directly related to production safety and efficiency. By understanding the working principles of products such as JYB-KO-M, mastering the selection points of models such as BTL-BTL70, and clarifying the quality standards of manufacturers such as SK1151-33X, corporate decision-makers can make wiser procurement decisions.
