Working Principle (Vibronic/Tuning Fork)
- Features a metal tuning fork vibrating at natural resonance (~85 Hz)
- In air/gas: Fork vibrates freely at higher frequency
- When liquid covers fork: Vibration dampens, frequency decreases, triggering state change
- Principle is independent of conductivity, dielectric constant, density (≥0.5 g/cm³), and viscosity (≤10,000 mm²/s)
Key Features
- Compact design for tight spaces, pipes, and small tanks
- No calibration required - plug-and-play operation
- Selectable failsafe mode (high for overfill protection/low for pump dry-run protection)
- Self-monitoring electronics with NAMUR NE 107 status signal
- Wide media compatibility (water, oils, aggressive chemicals)
- Maintenance-free operation (no moving parts)
- SIL2/3 certified according to IEC 61508
Technical Specifications
- Measuring task: Point level detection in liquids
- Process temperature: -40°C to +150°C (standard), up to 280°C (special versions)
- Process pressure: Up to 40 bar (580 psi)
- Density limit: ≥0.5 g/cm³
- Viscosity range: Up to 10,000 mm²/s
- Pipe diameter: ≥25 mm
- Output options: Relay (SPDT), PNP/NPN transistor, 2-wire AC/DC, NAMUR signal, Fieldbus
- Ingress protection: IP66/67, NEMA 4X
- Explosion protection: ATEX, IECEx, FM, CSA, NEPSI
Applications
- Overfill protection in tanks and vessels
- Dry-run protection for pumps
- Leak detection in pipelines
- Safety-critical loops (SIL-rated shutdown)
- Ideal for water/wastewater, chemical/petrochemical, oil/gas, food/beverage, and power plants
