VEGAVIB 62 Vibration Level Switch Overview
VEGAVIB 62 is a vibrating level switch for solid particle level measurement, widely used in mining, building materials, chemical, and food industries. It drives a vibrating rod via piezoelectric ceramics. When material covers the vibrating rod, the amplitude changes, thereby outputting a switching signal. Based on the official Chinese manual, this article summarizes selection, installation, and commissioning points.
Working Principle and Core Advantages
Vibration Measurement Principle
The vibrating rod vibrates at resonance frequency in air. When covered by material, vibration damping increases, amplitude decreases, and the electronic unit detects the change and outputs a relay signal. This principle is not affected by material dielectric constant, humidity, temperature, etc., making it suitable for complex conditions such as dust and adhesion.
Main Features
- Maintenance-free: no moving parts, extremely low wear.
- High reliability: not affected by changes in material properties.
- Wide applicability: can measure minimum particle density ≥0.02 g/cm³.
- Multiple outputs: relay, transistor, or NAMUR output options.
Technical Parameters and Selection
Key Parameter Table
| Parameter | Value/Description |
|---|---|
| Process temperature | -40 ~ +150°C |
| Process pressure | -1 ~ +16 bar |
| Minimum particle density | 0.02 g/cm³ |
| Output signal | Relay/Transistor/NAMUR |
| Protection rating | IP66/IP67 |
| Process connection | Thread/Flange |
Selection Notes
- Confirm whether the material particle density meets the minimum value.
- Select the corresponding model based on process temperature and pressure.
- Consider the installation location to avoid material impact and adhesion.
- The output method must match the control system.
Installation Steps and Commissioning
Installation Steps
- Confirm the installation point, avoiding the feed inlet and agitator.
- Install horizontally or vertically, with the vibrating rod extending into the container.
- Tighten the process connection to ensure sealing.
- Wire and power on, observe the indicator light status.
Commissioning Method
- In an empty tank, adjust sensitivity until the indicator light turns on.
- Add material to cover the vibrating rod; the indicator light should turn off.
- If false triggering occurs, fine-tune sensitivity or check the installation position.
- Record commissioning parameters for future maintenance.
Common Issues and Maintenance
- No signal output: check power supply and wiring.
- False alarm: adjust sensitivity or clean adhesion on the vibrating rod.
- Vibrating rod wear: inspect regularly and replace if necessary.
- Seal failure: replace the sealing ring and retighten.
Regular maintenance can extend the service life of the VEGAVIB 62 and ensure stable level measurement. For more details, please download the complete Chinese manual.
