Installation and Commissioning Steps
Correct installation is a prerequisite for ensuring the measurement accuracy of VEGABAR 28. Please follow the steps below and refer to the detailed illustrations in the Chinese manual.
- Confirm that the process connection specifications match the pipeline interface and check that the seals are intact.
- Install the transmitter vertically or horizontally at the measurement point, avoiding installation near pipe elbows or vibration sources.
- Tighten the process connection to ensure no leakage, taking care not to exceed the maximum torque.
- Connect the power supply and signal cables, paying attention to polarity, and ground the shielded cable at one end.
- After power-on, use a HART communicator or commissioning software to calibrate zero point and span.
- Check whether the output signal is stable and confirm that the measured value meets process requirements.
Selection Considerations
When selecting, comprehensive consideration should be given to the measuring medium, pressure range, process temperature, and connection method. The following points can help procurement and technical personnel make quick decisions.
- Medium compatibility: Corrosive media require appropriate diaphragm material.
- Range selection: It is recommended that the working pressure be between 30%…70% of the range.
- Process connection: Select threaded or flanged connection according to pipeline standards.
- Output signal: Select 4…20 mA or HART communication according to the control system.
- Environmental conditions: Accessories are required for high-temperature or high-vibration occasions.
Common Problems and Maintenance
Common Problems
- No output signal: Check power supply and wiring polarity.
- Large measurement deviation: Recalibrate zero point and check whether the process connection is blocked.
- Signal fluctuation: Confirm good grounding and stay away from interference sources.
Routine Maintenance
- Regularly check the sealing of the process connection.
- Clean the diaphragm surface to avoid scaling affecting measurement.
- Perform calibration verification according to the manual cycle.
