In the field of flow control equipment, the accuracy and stability of pressure transmitters directly affect system performance. This article presents professional field test results for the EDYLBSQ-43 pressure transmitter, and provides authoritative reference data for technical evaluators through a comparison of key data based on diffused silicon technology. The measured data from Xi'an Shenghongchuang Instrumentation Co., Ltd. will help you make precise model selection decisions.

Core Technical Features of the EDYLBSQ-43 Pressure Transmitter

As a high-performance pressure transmitter based on the diffused silicon principle, the EDYLBSQ-43 adopts a monocrystalline silicon piezoresistive design. Its core sensor is processed with laser trimming compensation technology, offering excellent temperature stability and overload resistance. Within the 0~10MPa range, the measured linearity error is ≤±0.1%FS, which is better than the 0.2% grade specified in the industry standard GB/T 17614.3-2015.

• Media Compatibility: Suitable for measuring gas, liquid, and steam media, with wetted parts made of 316L stainless steel
• Environmental Adaptability: Operating temperature -40℃~125℃, IP67 protection rating
• Output Signal: 4~20mA analog output superimposed with HART protocol, supporting remote calibration

Analysis of Measured Accuracy Data (Compared with Similar Products such as AST-C1000)

Compared with models such as PT500-50M-10V-0.5-M20-3m-503, the EDYLBSQ-43 shortens the dynamic response time to 8ms under pulsating pressure conditions, making it particularly suitable for rapid pressure monitoring in hydraulic systems.

Stability Verification Scheme for Diffused Silicon Sensors

Through a 6-month accelerated aging test (85℃/85%RH environment), actual service conditions equivalent to 5 years of use were simulated. The test data show:

1. The zero-point drift is only 0.02%FS, far lower than the 0.1%FS of traditional models such as DG1300-BZ-A-2-210/CJ/GZ
2. The sealing performance remains stable, with a helium mass spectrometry leak rate of ＜1×10⁻⁹ Pa·m³/s
3. Key parameters comply with the certification requirements of the ISO 9001:2015 quality management system

Performance in Typical Application Scenarios

In the flow control system of a refinery in the petrochemical industry, the parallel testing results of 20 EDYLBSQ-43 units and MYR-22 transmitters show:

• In media containing hydrogen sulfide, the annual failure rate is reduced by 62%
• Compared with ZY800-V1-B1-C1-J1P1, the maintenance cycle is extended to 36 months
• The overall uncertainty of the measurement system reaches Class 0.25

Model Selection Recommendations and Key Technical Evaluation Points

For users who require high-precision diffused silicon liquid and gas pressure sensors, it is recommended to focus on:

• Media Characteristic Matching: For corrosive media, choose special diaphragm models such as PTS702Q-400M-MA-C-M20
• Accuracy Verification: Require suppliers to provide third-party testing reports (such as those bearing the CMA mark)
• Cost-Performance Analysis: Economical products such as KYB-G have a lower initial cost, but their total life-cycle cost may be higher
