In the field of industrial automation control, the accuracy of the 26.600G-X102 pressure transmitter directly affects system stability. This article focuses on two accuracy classes, 0.1%FS and 0.25%FS, and compares and analyzes their performance differences in diffused silicon liquid and gas pressure sensor applications through practical testing, providing key selection criteria for technical evaluators.

I. Technical Principles and Industry Background of Diffused Silicon Pressure Sensors

As a core component of flow control equipment, the 26.600G-X102 pressure transmitter adopts the diffused silicon piezoresistive effect principle. When the pressure of the measured medium acts on the sensing element, the silicon diaphragm deforms, causing a change in the resistance value of the Wheatstone bridge, and the signal conditioning circuit outputs a standard current/voltage signal. In accordance with ISO 9001:2015 certification requirements, the GPD-GPD25 pressure transmitter series produced by Xi'an Shenghongchuang Instrumentation Co., Ltd. strictly complies with the IEC 60770 standard, and its diffused silicon liquid and gas pressure sensor display module supports dual 4-20mA/HART protocol output, meeting the explosion-proof certification requirements of industries such as petrochemical and power.

1.1 Current Market Segmentation of Accuracy Requirements

According to 2023 industry research data, in the process control field:

• 68% of steam flow measurement scenarios use transmitters with 0.25%FS accuracy
• 90% of fermentation tank pressure monitoring in the pharmaceutical industry requires 0.1%FS accuracy
• The energy industry has a gray tolerance zone of ±0.15%FS for the accuracy of the MPM480E22B1C1A pressure transmitter

II. Measured Performance Comparison Between 0.1%FS and 0.25%FS

Based on the DG1300-BZ-A-2-35/FC/GZ pressure transmitter test platform, we simulated three typical operating conditions:

III. Technical Selection Decision Tree Model

For the accuracy selection of the 26.600G-X102-R-1-8-100-R40-1-000 pressure transmitter, it is recommended to follow the decision process below:

1. System error budget analysis: when the total system error requirement is ≤0.2%, the 0.1%FS model must be selected
2. Medium characteristic evaluation: for corrosive media, it is recommended to use the 0.1%FS model to compensate for diaphragm deformation error
3. Life cycle cost calculation: the procurement cost of the 0.25%FS model is 30% lower, but the calibration cycle is shortened by 40%
