Unveiling the Working Principle of Diffused Silicon Hysteresis Pressure Sensors

As a core component in the field of industrial automation, the JYB-KO-M diffused silicon hysteresis pressure sensor, with its unique working principle, demonstrates outstanding accuracy and stability in the field of pressure measurement. This article provides an in-depth analysis of its working principle, helping business decision-makers understand how to achieve precise pressure monitoring through this high-performance sensor, and offering professional guidance for the selection and application of YB-YB3101, TXY-TXY801, and other series products.

I. Technical Core: Diffused Silicon Strain Principle

The core of the JYB-KO-M pressure transmitter lies in its use of the piezoresistive effect of monocrystalline silicon material. When pressure acts on the sensor diaphragm, the silicon crystal undergoes slight deformation, causing a change in the internal resistance value. Through the Wheatstone bridge, the resistance change is converted into a standard 4-20mA signal output, achieving linear conversion of the pressure value. This process complies with the IEC 60770 international standard, and the measurement error can be controlled within ±0.1%FS, far exceeding the accuracy of traditional ceramic capacitive sensors.

III. Analysis of Typical Application Scenarios

In the petrochemical field, the SK1151-33X model has become the preferred choice for reactor pressure monitoring благодаря its explosion-proof certifications (ATEX/IECEx); while the LYB-LYB3008, due to its IP68 protection rating, is widely used in water conservancy monitoring systems. For the food and pharmaceutical industries, we recommend the NPT-NPT100 series made of 316L stainless steel, with a surface roughness of Ra≤0.8μm, complying with FDA hygiene standards.

IV. Selection Decision Tree Guide

1. Determine the properties of the measured medium (corrosiveness/viscosity)
2. Select the process connection method (thread/flange/clamp)
3. Match the output signal type (if on-site display is required, the integrated industrial digital display temperature transmitter domestic temperature transmitter KZW-B composite solution can be considered)
4. Confirm explosion-proof/protection rating requirements
