VEGAVIB 63 Product Overview
VEGAVIB 63 is a vibrating level switch launched by VEGA for solid material detection. It uses piezoelectric ceramics to drive the tuning fork probe to vibrate. When the material covers the probe, the vibration amplitude attenuates, thereby outputting a switching signal. This instrument is widely used for high and low limit alarms and control of solid materials such as powders and granules.
This Chinese manual aims to provide complete technical reference for engineering technicians and procurement personnel, covering installation, commissioning, parameter setting, and maintenance points.
Working Principle and Core Advantages
Vibrating Detection Principle
The tuning fork probe of VEGAVIB 63 vibrates at the resonant frequency under piezoelectric excitation. When the material contacts the probe, the vibration damping increases, the amplitude decreases, and the electronic unit detects this change and outputs a switching quantity. This principle is not affected by changes in material dielectric constant, humidity, temperature, etc., and has high reliability.
Main Technical Features
- Maintenance-free: No moving parts, minimal wear, long service life.
- Anti-adhesion: The tuning fork structure is insensitive to sticky materials, reducing false alarms.
- Wide applicability: Can measure solid powders with a minimum density as low as 20 g/l.
- Multiple outputs: Supports relay, transistor, NAMUR, and other output methods.
- High protection rating: Optional IP66/IP67 and Ex explosion-proof certification.

Installation and Commissioning Steps
Installation Precautions
- The installation position should avoid direct impact from the feed inlet to prevent damage to the probe.
- For horizontal installation, the tuning fork should be tilted downward about 15° to reduce material accumulation.
- Ensure the probe extends fully into the silo to avoid material buildup caused by an excessively long installation nozzle.
- For sticky materials, it is recommended to choose a model with an extension tube.
Commissioning Process
- Confirm that the supply voltage matches the instrument nameplate and that the wiring is correct.
- After power-on, observe the indicator light status: when normally uncovered, the indicator light is steady on or flashing (depending on mode).
- Use a flathead screwdriver to adjust the sensitivity potentiometer until a stable detection state is achieved.
- Perform a material coverage test to verify reliable output signal action.
- Lock the cover and record the commissioning parameters.
Common Issues and Maintenance
Troubleshooting
- No output signal: Check the power supply, fuse, and wiring terminals.
- False alarm: May be caused by material adhesion on the probe or excessively high sensitivity setting. Clean and readjust.
- Weakened vibration: Check whether the tuning fork is deformed or damaged, and replace the probe if necessary.
Daily Maintenance
VEGAVIB 63 is basically maintenance-free. It is recommended to regularly check the probe for mechanical damage or severe adhesion. In explosion-proof applications, periodic insulation and grounding checks must be carried out according to the manual requirements.
Summary
VEGAVIB 63, with its reliable vibration detection principle and robust design, is an ideal choice for solid level detection.
