Selection Guide for Diffused Silicon Pressure Transmitters

In the field of flow control equipment, how can the measurement range of the DYB-HAG pressure transmitter be accurately selected? Diffused silicon liquid and gas pressure sensors are widely used due to their outstanding performance. This article provides a comprehensive analysis of the measurement accuracy, service life, and matching instrument selection techniques for models such as TCP-TCP1 and ZD-803, helping technical evaluators choose the optimal solution based on actual operating conditions.

I. Scientific Methods for Selecting the Measurement Range

The selection of the measurement range for the DYB-HAG pressure transmitter should comprehensively consider the following key factors:

• Operating pressure level: It is recommended to select a model with a maximum range of 1.5 times the normal working pressure. For example, the PT-PT500 series can cover industrial scenarios of 0-10MPa
• Medium characteristics: Corrosive media require models such as ZC-316 with a special diaphragm structure
• Temperature impact: The LXB-184 series has a built-in temperature compensation module, suitable for wide-temperature environments of -40℃~125℃

According to the GB/T 17614-2018 standard, an additional 20% overload margin should also be reserved when selecting the range of diffused silicon sensors. For example, in water supply pipeline network monitoring, the DYB-HAG-06 model (0-1.6MPa) is more suitable than DYB-HAG-05 (0-1MPa) for handling pressure fluctuations.

II. Comparative Analysis of Key Performance Parameters

It is worth noting that models such as PT-PT115, which use original genuine sensor chips, demonstrate better repeatability accuracy (≤±0.05%) in continuous monitoring in the chemical industry.

III. Matching Instruments and System Integration Solutions

A complete pressure measurement system needs to be matched with appropriate supporting equipment:

1. Signal conversion module: The JF-JF316 signal conditioner can convert the original signal into a 4-20mA standard output
2. Display control unit: The intelligent digital display meter paired with the LXB-183 transmitter supports the MODBUS RTU protocol
3. Calibration equipment: It is recommended to use the dedicated PT-PT500 calibrator for periodic calibration

In actual system integration, it can be paired with domestic ultrasonic flowmeter ZRN-3000 clamp-on ultrasonic flowmeter pipeline water flowmeter to build a multi-parameter monitoring network. Its ±1.0% measurement accuracy can form complementary verification with pressure transmitter data.

IV. Typical Industry Application Scenarios

According to differences in medium characteristics, diffused silicon sensors need to be selected specifically for the application:

• Petrochemical industry: PT-PT500 explosion-proof type + Hastelloy diaphragm combination
• Water supply pipeline network: ZC-316 sanitary type + IP68 protection rating configuration
• Compressed air5-7 years

  It is worth noting that models such as PT-PT115, which use original genuine sensor chips, demonstrate better repeatability accuracy (≤±0.05%) in continuous monitoring in the chemical industry.

  • Compressed air system: JK-180 economical type + with damping adjustment function

  Especially in the field of gas metering, the DYB-HAG series must pass SIL2 certification and be paired with original genuine accessories to ensure safe operation.

  
  

  Professional Technical Summary

  When selecting a diffused silicon pressure transmitter, technical evaluators should establish a three-dimensional evaluation model:

  1. The degree of matching between accuracy stability and operating conditions
  2. Protocol compatibility of supporting instruments
  3. Full life-cycle maintenance costs

  As a professional manufacturer in the field of pressure measurement, we recommend regular maintenance using original genuine accessories, which can extend equipment service life by more than 30%.
