Installation and Commissioning Key Points
Installation Precautions
Correct installation is a prerequisite for ensuring measurement accuracy. Please follow these steps:
- Confirm that the instrument model matches the process connection and check if the seals are intact.
- Install the probe vertically on the top or side of the tank, avoiding proximity to the feed inlet or agitator.
- Ensure sufficient distance between the probe end and the tank bottom to prevent interference from buildup.
- Tighten the process connection, but avoid excessive force that may damage threads or flanges.
- For hazardous areas, intrinsically safe or flameproof configurations must be used, and reliable grounding is required.
Commissioning Steps
Commissioning can be done via local buttons or a HART communicator. The basic procedure is as follows:
- After power-on, check whether the instrument self-test passes.
- Set the empty tank calibration (zero point) and full tank calibration (span).
- Adjust the damping time and sensitivity according to the medium characteristics.
- Verify that the output current matches the displayed value.
- Record the commissioning parameters and lock the settings to prevent misoperation.
Typical Application Scenarios
VEGASTAB 690 is suitable for various industrial occasions, especially the following fields:
- Chemical storage tanks: Measuring levels of acids, alkalis, solvents, etc.
- Water treatment: Measuring levels of clean water, wastewater, and sludge interface.
- Food and beverage: Hygienic connections for milk, syrup, etc.
- Pharmaceutical industry: Meeting cleanliness requirements, measuring liquid medicine or powder.
- Energy and power: Level monitoring of boiler drums, demineralized water tanks, etc.
Selection and Procurement Recommendations
When purchasing VEGASTAB 690, the following information must be clarified to ensure correct selection:
- Medium characteristics: Dielectric constant, viscosity, corrosiveness, and whether it is prone to buildup.
- Process conditions: Temperature, pressure, vacuum, or positive pressure.
- Installation method: Thread, flange specifications, and materials.
- Output and certifications: Required signal type, explosion-proof certification, hygienic certification.
