VEGAVIB 61 Product Overview
VEGAVIB 61 is a vibrating level switch launched by VEGA, mainly used for level limit detection of solid particles or powders. It uses piezoelectric drive to make the tuning fork vibrate. When the material covers the tuning fork, the vibration amplitude changes, thereby outputting a switching signal. This product is widely used in silos, storage tanks, discharge outlets, and other occasions.

Working Principle and Typical Applications
Vibrating Tuning Fork Detection Principle
The tuning fork of VEGAVIB 61 is driven by piezoelectric ceramics and vibrates at the resonant frequency. When the material covers the tuning fork, the vibration damping increases and the amplitude decreases. The electronic module detects the change and outputs a switching value. This principle is insensitive to dust and adhesion and has high reliability.
- Applicable materials: granules, powders, fine materials, such as cement, flour, plastic pellets, sand and gravel, etc.
- Output mode: relay, transistor, or NAMUR output, optional.
- Process connection: thread, flange, various materials available.
Typical Application Scenarios
- Silo high/low level alarm
- Discharge outlet blockage detection
- Storage tank overflow protection
- Material presence detection in conveying pipelines

Installation Points
Selection of Installation Position
The installation position should avoid direct impact of material on the tuning fork, while ensuring that the tuning fork can fully contact the material. For high level detection, it is recommended to install at the top of the silo; for low level detection, install at the bottom or side wall.
- Avoid installation directly below the feed inlet to prevent impact damage.
- When installed on the side wall, the tuning fork should extend into the silo to avoid material buildup.
- Ensure that the vibration direction of the tuning fork is not blocked.
Electrical Connection
Before wiring, confirm that the supply voltage matches the instrument nameplate. Open the housing and connect the power and output signal wires according to the terminal markings. It is recommended to use shielded cables and ensure reliable grounding.
- Open the instrument cover after power off.
- Pass the cable through the cable entry.
- Connect the power and output terminals according to the wiring diagram.
- Tighten the cable entry to ensure sealing.
- Restore power and perform a function test.
Commissioning and Maintenance
Commissioning Steps
VEGAVIB 61 usually requires no complicated commissioning and can work after power-on. Whether the tuning fork is covered can be judged by the indicator light or output status.
- Confirm that the power supply is normal and observe the indicator light.
- When the silo is empty, the output should be in the "uncovered" state.
- Gently touch the tuning fork with a tool to simulate material coverage, and the output should switch.
- If the output is abnormal, check the sensitivity setting or medium adhesion.
Daily Maintenance
- Regularly check whether the tuning fork has material adhesion or damage.
- Avoid using hard objects to scrape the fork body during cleaning.
- Check whether the cable entry seal is aging.
- After long-term shutdown, power on again and perform a function test.
Selection and Procurement Suggestions
When purchasing VEGAVIB 61, it is necessary to clarify the process temperature, pressure, medium characteristics, output type, and process connection. It is recommended to request the VEGAVIB 61 Chinese Manual to verify detailed parameters.
- Choose the high-temperature type for high-temperature conditions.
- Choose corrosion-resistant materials for corrosive media.
- Choose explosion-proof certified models for explosion-proof occasions.
- Confirm that the output matches the control system.
