Installation and Commissioning Points
Correct installation and commissioning are key to ensuring the measurement accuracy of the VEGASCAN 693. The following steps and precautions can help you quickly complete on-site deployment.
Installation Steps
- Confirm the installation position: Avoid the feed inlet and agitator, and ensure there are no fixed obstacles within the radar beam range.
- Fix the instrument: Use flange or threaded connection to ensure sealing, and note that the antenna direction should be perpendicular to the material surface.
- Electrical connection: Connect the power and signal cables according to the wiring diagram in the manual, and pay attention to shielding layer grounding.
- Parameter setting: Enter the empty tank height, full tank height, and medium characteristics via the display module or commissioning software.
- Verify measurement: Observe the echo curve and adjust the suppression range if necessary to eliminate false echoes.
Commissioning Precautions
- Avoid condensation: In low-temperature or high-humidity environments, ensure there is no condensation on the antenna surface; otherwise, signal strength will be affected.
- Medium dielectric constant: For low dielectric constant media (such as certain plastic pellets), high-frequency radar or guided wave radar should be selected.
- Agitation applications: Strong agitation can generate foam and vortices; it is recommended to choose models with echo suppression function.
Typical Application Scenarios
The VEGASCAN 693 is suitable for various industrial processes, especially performing excellently in water treatment, chemical storage tanks, and food processing. Its non-contact measurement method avoids wear and contamination, resulting in low maintenance costs.
- Water treatment: Measure the liquid level of pools and water towers, and cooperate with pump control to achieve automatic water replenishment.
- Chemical storage tanks: Monitor the inventory of liquids such as acids, alkalis, and solvents to ensure safe storage.
- Food processing: Measure media with high hygiene requirements such as syrup and edible oil, complying with hygiene standards.
- Bulk solids: Such as cement, flour, and plastic pellets in silos, where dust interference must be noted.
Selection and Procurement Recommendations
When purchasing the VEGASCAN 693, the process connection, antenna material, output signal, and certification requirements must be confirmed according to actual working conditions. It is recommended to request the complete Chinese manual and selection samples for technical comparison.
- Process connection: Flange standard (DN50/DN80, etc.) or thread (G1½, NPT).
- Antenna material: PTFE, stainless steel, or ceramic, with different corrosion and temperature resistance.
- Certification: Explosion-proof applications require ATEX, IECEx, or intrinsically safe certification.
- Display and commissioning: Optional display module or Bluetooth commissioning function.
Common Problems and Maintenance
To extend the service life of the VEGASCAN 693, regular inspection of antenna cleanliness and signal strength is essential. If measurement fluctuations occur, refer to the troubleshooting chapter in the manual.
- Measurement value jumps: Check for interfering echoes and re-learn the suppression curve.
- No signal output: Confirm whether the supply voltage and loop load resistance match.
- Accuracy degradation: Clean the antenna surface and check whether the medium is adhering or scaling.
