Installation and Wiring Guide
Installation Steps
- Confirm that the installation location is free from strong vibration and corrosive gases, and reserve sufficient maintenance space.
- Use appropriate tools to fix the instrument on the bracket or pipeline, ensuring the sealing ring is intact.
- Connect the power and signal lines according to the wiring diagram, paying attention to polarity and shielding layer grounding.
- After power-on, observe the indicator light status; normal should be steady green or flashing.
Wiring Precautions
- Use shielded twisted pair to reduce electromagnetic interference.
- Route power and signal lines separately to avoid parallel laying.
- Ensure grounding resistance is less than 4Ω, and keep the grounding wire as short as possible.
Commissioning and Troubleshooting
Before commissioning, confirm that the power supply is normal and wiring is correct. If the output is abnormal, refer to the following common problems.
| Symptom | Possible Cause | Solution |
|---|---|---|
| No output | Power reversed or open circuit | Check power polarity and line continuity |
| Large output fluctuation | Interference or poor grounding | Improve shielding and grounding, stay away from interference sources |
| Display value deviation | Sensor not calibrated | Re-calibrate zero and span |
Maintenance and Selection Recommendations
Regularly check the sealing and wiring terminals of 93TA1; calibration every 12 months is recommended. For corrosive media, diaphragm seals or corrosion-resistant housings should be selected.
When selecting, clarify the measurement range, process connection specifications, output signal, and explosion-proof requirements to ensure compatibility with the existing control system.
- Confirm process connection: thread or flange specifications.
- Confirm electrical interface: M20×1.5 or 1/2NPT.
- Confirm whether HART communication or local display is required.
