Installation and Commissioning Steps
Correct installation and commissioning are key to ensuring long-term stable operation of the VEGABAR 18. The following steps apply to conventional working conditions.
- Installation location selection: Avoid installation in locations with strong vibration or sudden temperature changes, and ensure the process connection is well sealed.
- Electrical connection: Connect the power and signal lines according to the wiring diagram in the manual, paying attention to polarity.
- Zero point calibration: Adjust the zero point under no pressure to ensure the output is 4 mA or 0 V.
- Range setting: Configure the range according to the actual measurement range, and adjust via handheld device or buttons if necessary.
- Function test: Apply standard pressure to verify the linearity and accuracy of the output signal.
Selection Precautions
During selection, comprehensive consideration should be given to medium characteristics, process pressure, temperature, and output requirements. The following points can help you make a quick decision.
- Medium compatibility: Confirm that the wetted materials (such as ceramics, stainless steel) are compatible with the medium.
- Pressure range: Leave a margin when selecting the range; it is recommended that the working pressure be 30%～80% of the range.
- Output type: Choose 4～20 mA or 0～10 V according to the control system interface.
- Process connection: Match the on-site pipeline thread standard.
- Certification requirements: If explosion-proof requirements exist, select the corresponding explosion-proof certified version.
