Key Points for System Integration of TXY-TXY Pressure Transmitters and Heshman Sensors

In industrial automation control systems, the system integration of TXY-TXY pressure transmitters and diffused silicon Heshman pressure sensors is of vital importance. This article provides a detailed analysis of key considerations such as supporting equipment selection, installation, and commissioning, helping technical evaluation personnel improve the matching performance of pressure transmitters such as PT124B-219 and FST800 series with Heshman sensors, ensuring measurement accuracy and service life.

1. Equipment Selection and Compatibility Verification

1.Parameter Matching Principles
Technical evaluation personnel should focus on verifying core indicators such as the measuring range of TXY-TXY pressure transmitters and Heshman sensors (such as FST800-201 range 5kg～20t), combined accuracy (0.02～0.03 class), and sensitivity (2.0±0.1mV/V). Taking PT124B-219 as an example, its operating temperature of -20℃～+65℃ needs to be synchronously verified with the sensor's characteristic of insulation resistance ≥5000MΩ.

2.Interface Standardization Requirements
The M12/M20 threaded interface of diffused silicon Heshman pressure sensors must precisely match the flange dimensions of YBX-YBX transmitters to avoid zero drift caused by mechanical stress. It is recommended to refer to the IEC 61518 standard for explosion-proof certification connection.

2. Technical Specifications for Installation and Commissioning

1.Key Points of Mechanical Installation
• Use a torque wrench to control the installation force of FST800-214 accessories (recommended value 20-30N·m)
• For YLT-YLT101 supporting instruments, it is necessary to keep the sensor axis parallel to the gravity direction, with a deviation ≤0.5°

2.Electrical Connection Protection
When using shielded twisted pair cables to connect TXU-TXU transmitters, it should be ensured that the bridge supply voltage fluctuation of 10VDC does not exceed ±5%. The grounding resistance must be ＜4Ω, in compliance with GB/T 15479-2015 specifications.

3. System Calibration and Performance Optimization

1.Dynamic Compensation Technology
For FST800-211A original genuine sensors, the zero-point temperature effect (±0.03%FS/℃) can be compensated through software. It is recommended to use the three-point calibration method: cyclically test the 0%, 50%, and 100% range points 3 times.

2.Service Life Extension Strategy
When the PT124B-219 pressure transmitter is paired with original German Heshman sensors, creep testing (standard value ±0.03%FS) should be carried out regularly. Every 2000 hours, the output stability under the 150% safe overload state must be checked.

4. Supporting Equipment Coordination Solution

In batching weighing systems, domestic weighing sensor HDW401 column-type tension sensor for batching silo aggregate scales can form a redundant measurement network with the FST800-202 pressure transmitter. Its alloy steel material and 0.02 class accuracy make it particularly suitable for force value control in chemical and metallurgical scenarios, with output symmetry error ＜0.5%FS.

Recommendations for System Integration Implementation

1.Preventive Maintenance Plan
Establish a quarterly performance testing system for FST800 series sensors, including:
• Input resistance 380±10Ω verification
• Output resistance 350±3Ω test
• Insulation resistance ≥5000MΩ inspection

2.Troubleshooting Process
When abnormalities occur in YLT-YLT101 supporting instruments, troubleshoot according to the following steps:
① Check bridge supply voltage stability (10VDC±0.5V)
② Test sensor output symmetry (tension and compression bidirectional deviation ≤1%)
③ Verify transmitter AD conversion linearity
