As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang provides you with a detailed explanation of the working principle of the KS-E-E-C-B01C-M-V diffused silicon pressure sensor. This article uses illustrated analysis to explain how this model utilizes the silicon diaphragm piezoresistive effect to achieve precise and stable pressure detection, helping technical evaluators gain an in-depth understanding of the core advantages and application scenarios of diffused silicon sensors in liquid/gas pressure measurement.

I. Core Working Principle of the Diffused Silicon Sensor

The core technology of the KS-E-E-C-B01C-M-V pressure transmitter lies in its diffused silicon piezoresistive sensing element. When the pressure of the measured medium (liquid or gas) acts on the silicon diaphragm, the diaphragm undergoes slight deformation, causing the resistance values of the Wheatstone bridge embedded on the diaphragm surface to change. This change has a linear relationship with the pressure value, and after amplification and temperature compensation through a dedicated integrated circuit (ASIC), it outputs a standard 4-20mA or 0-10V signal.

1.1 Illustrated Explanation of the Silicon Diaphragm Piezoresistive Effect

Xi'an Shenghongchuang's KS series sensors use monocrystalline silicon material, and four pressure-sensitive resistors are formed on the surface of the silicon diaphragm through ion implantation technology, constituting a full-bridge circuit. When pressure P acts on the diaphragm:

• The resistance values of R1 and R3 in the compression zone increase
• The resistance values of R2 and R4 in the tension zone decrease
• Bridge output voltage ΔV=K×P (K is the sensitivity coefficient)

This design enables the linearity of the KS-E-E-C-B01C-M-V to reach ±0.1%FS, 3-5 times better than traditional strain gauge sensors.

II. Stability Design of the KS-E-E-C-B01C-M-V

To address the long-term stability concerns of technical evaluators, this model adopts a triple protection mechanism:

2.1 Temperature Compensation Technology

The built-in temperature sensor monitors environmental changes in real time and corrects temperature drift through digital algorithms. Test data shows that within the range of -20~85℃, its temperature error is less than ±0.02%FS/℃, significantly better than similar GT-V pressure transmitters.

2.2 Medium Compatibility Treatment

The medium-contacting parts use a 316L stainless steel isolation diaphragm + fluororubber sealing ring, which can withstand:

III. Performance Comparison with Similar Products

When selecting diffused silicon liquid and gas pressure sensors, technical evaluators often face choices among models such as KS-E-E-Z-B04U-M-V and GT-V. The comparison of key indicators is as follows:

3.1 Accuracy and Stability

• KS-E-E-C-B01C-M-V: ±0.1%FS annual drift, passed 5 million pressure cycle tests
• GT-V pressure transmitter: ±0.25%FS annual drift, zero-point drift occurred after 3 million tests
• MBS-G5734: ±0.15%FS, but performance declines significantly in high-temperature environments

3.2 Application Scenario Adaptability

Xi'an Shenghongchuang's KS series is particularly suitable for:

1. Hydraulic system pressure monitoring (requires CYBB-CYBB1 flange connection)
2. Natural gas pipeline safety monitoring (complies with GB3836 explosion-proof certification)
3. Clean environments in the pharmaceutical industry (surface roughness Ra≤0.8μm)

IV. Technical Selection Recommendations

For different application requirements, we recommend that technical evaluators refer to the following criteria:

4.1 Key Parameter Matching

• Range selection: The actual working pressure should be between 30%-70% of the sensor range
• Output signal: 4-20mA is suitable for long-distance transmission, 0-5V is suitable for direct PLC acquisition
• Process connection: The YXK-YXK series provides multiple thread options such as G1/4 and NPT1/2

4.2 Quality Verification Methods

When verifying products such as the P-UA pressure transmitter, it is recommended to perform:

1. 24-hour zero-point stability test (variation should be <0.05%FS)
2. Step pressure response test (response time of KS-E-E-C-B01U-M-V <1ms)
3. Medium compatibility test (refer to GB/T15478 standard)
