Introduction

As core equipment in the pressure measurement field, the CYG1101 pressure transmitter has attracted significant attention thanks to its diffused silicon sensor technology. Based on measured data from 1000 hours of continuous operation, this report provides an in-depth analysis of the stability performance of this model in liquid/gas pressure monitoring, offering reliable selection reference for industrial users.

Working Principle and Advantages of Diffused Silicon Sensor Technology

The diffused silicon sensor is the core component of the CYG1101 pressure transmitter, and its working principle is based on the piezoresistive effect. When external pressure acts on the silicon diaphragm, the diaphragm undergoes slight deformation, causing the resistance value of the embedded Wheatstone bridge to change, thereby outputting an electrical signal proportional to the pressure. Compared with traditional strain gauge sensors, diffused silicon technology has the following significant advantages:

• High sensitivity: The piezoresistive coefficient of silicon material is 50-100 times that of metal, enabling detection of tiny pressure changes
• Long-term stability: The monocrystalline silicon structure has no creep or fatigue effect, making it suitable for long-term continuous operation
• Excellent temperature characteristics: Built-in temperature compensation circuit, with an operating temperature range up to -40℃~125℃
• Strong media compatibility: The 316L stainless steel isolation diaphragm can measure corrosive liquids and gases

Xi'an Shenghongchuang Instrument Co., Ltd. uses imported German silicon wafers, and the consistency of sensor chips manufactured through semiconductor processes can reach ±0.1%, providing a reliable technical foundation for products in the same series such as P-A1012 and MBS3050.

Measured Data from 1000 Hours of Continuous Operation

Test Environment and Parameter Settings

This test simulated industrial field working conditions and used the HC802 pressure calibration system to continuously monitor the CYG1101:

Analysis of Key Performance Indicators

Through statistical analysis of 6000 sets of sampled data, the following conclusions were obtained:

1. Zero drift: The cumulative variation was ≤0.05%FS, better than the industry average level of 0.1%FS for the HB2126 model
2. Full-scale error: It remained within ±0.2% throughout, meeting the committed specifications of the DYP418 manufacturer
3. Repeatability error: The standard deviation during the test cycle was only 0.018%, proving the stability of the sensor's mechanical structure
4. Temperature effect: Under a simulated day-night temperature difference environment, the additional error was ≤0.03%/℃

It is particularly worth noting that when the test reached 800 hours, 3 pressure shocks were artificially created (instantly reaching 2 times the full scale), and the sensor was still able to quickly restore stable output, proving that its overload protection design is effective.

Recommendations for Industrial Application Scenarios

Liquid Pressure Monitoring Solutions

For liquid pressure monitoring scenarios such as water pump stations and pipeline transportation, it is recommended to:

• Select the corrosion-resistant connector matched with the J502 model to prevent medium crystallization blockage
• The installation position should avoid pipeline bends and valves, and the straight pipe section length should be ≥5 times the pipe diameter
• Perform zero calibration regularly, with a recommended interval of 3 months (according to the MH310 user manual)

Gas Pressure Control Applications

When used in systems such as compressed air stations and gas pressure regulation, note the following:

• Give priority to 8251 series products with explosion-proof certification
• Strict leak testing must be carried out before installation
• It is recommended to use the damper of the MBS3050 model together to eliminate the impact of pulsating pressure

Selection Comparison and Quality Verification

Compared with similar products on the market, the CYG1101 performs prominently in the following aspects:
