Design & Functionality
The vibration sensing mechanism works by generating a stable oscillation in the fork element. When the fork comes into contact with liquid, the vibration frequency changes, triggering the switching output. This method ensures highly reliable detection even in liquids with varying densities, foam presence, or turbulence.
Constructed with AISI 316L stainless steel for all wetted components, the sensor resists corrosion, chemical exposure, and high temperatures. The rugged die-cast aluminum housing protects the internal electronics from environmental factors while maintaining stable operation in industrial installations.
Because the device contains no moving mechanical parts, it significantly reduces maintenance requirements and minimizes operational downtime.
Total Crossed Beams
The vibration detection system maintains a stable oscillation pattern that quickly reacts to liquid presence. This allows the sensor to deliver precise switching signals when liquid levels reach the detection point, improving process reliability and system automation.
Beam Pitch Options
The design supports different installation configurations including threaded or flanged mounting options. Extension lengths can be customized for various tank sizes, making the sensor suitable for diverse industrial environments and vessel dimensions.
Intrinsic Synchronism
The integrated electronic control system maintains stable vibration frequency and ensures consistent switching accuracy even in fluctuating temperature or pressure conditions. This built-in synchronization enables reliable detection in complex industrial processes.
Operational Advantages
Industrial plants rely on stable level monitoring to prevent overfilling, dry running, and process interruptions. The vibration-based detection method ensures reliable operation regardless of liquid conductivity or dielectric properties.
With high thermal resistance and durable materials, the sensor performs effectively in industries such as:
- Chemical processing
- Food and beverage production
- Water treatment systems
- Oil and petrochemical facilities
By combining robust construction with precise vibration sensing technology, this device delivers dependable level detection for demanding industrial environments.
