Selection Notes
- Measuring range: It is recommended to select the actual working pressure between 30%-70% of the range to ensure accuracy.
- Process connection: Choose threaded or flange connection according to the pipeline interface.
- Output signal: Match with the control system, such as PLC or DCS.
- Certification requirements: For explosion-proof occasions, choose intrinsically safe or flameproof type.
Installation and Commissioning Steps
Correct installation and commissioning are key to ensuring the long-term stable operation of VEGABAR 39. Please follow the steps below:
- Installation position: Choose a location convenient for observation and wiring, avoiding strong vibration and heat sources.
- Process connection: Use appropriate gaskets, tighten according to torque requirements, and ensure no leakage.
- Electrical connection: Refer to the wiring diagram in the manual, connect power and signal lines, and pay attention to polarity.
- Parameter setting: Set parameters such as range and damping through the display module or HART handheld communicator.
- Zero calibration: Perform zero adjustment under no pressure to ensure accurate output.
Common Troubleshooting
- No output signal: Check whether the power supply and wiring are normal.
- Output fluctuation: Check whether the process pressure is stable, or increase the damping time.
- Measurement deviation: Recalibrate the zero point and check whether the process connection is blocked.
Maintenance and Care
Regularly check the appearance and wiring of VEGABAR 39, and clean deposits at the process connection. It is recommended to perform calibration every 12 months to ensure measurement accuracy. If damage is found, please contact a VEGA authorized service provider promptly.
