The GVS25AT vibrating fork level switch is a high-performance industrial sensor developed for accurate bulk solid level detection in silos, hoppers, tanks, and process containers. Designed to operate in demanding manufacturing environments, it offers exceptional reliability even under extreme temperatures up to 200°C. With advanced vibrating fork technology, the sensor detects material presence by monitoring frequency variations, ensuring precise level indication for powders, granules, and bulk materials.
This robust level detection solution is widely used in industries such as food processing, cement production, chemical manufacturing, plastics processing, ceramics, and recycling operations. Its maintenance-free operation and easy installation make it a practical choice for automated process control and industrial material handling systems.
Key Features
The sensor combines industrial durability with highly accurate level detection technology.
Key advantages include:
- Reliable vibrating fork sensing technology for bulk solids
- Suitable for powders, pellets, and granular materials
- High temperature resistance up to 200°C
- Maintenance-free operation with no calibration required
- Corrosion-resistant stainless steel sensing fork
- Fast response time for process automation systems
- Compatible with various industrial level monitoring systems
These features make it ideal for modern process automation and Industry 4.0 material management systems.
Design & Functionality
The GVS25AT uses vibration-based sensing to detect the presence or absence of solid materials. When the fork is free, it vibrates at a specific frequency. When material contacts the fork, the vibration frequency changes, triggering the switching output.
This simple yet highly reliable detection principle allows the sensor to operate effectively even in dusty or harsh industrial environments where other level measurement technologies may fail.
The device is engineered with durable industrial materials, including a robust aluminum housing and stainless-steel process components that ensure long service life and resistance to corrosion.
Total Crossed Beams
The vibrating fork structure forms a precise sensing zone that reacts immediately when material reaches the probe. This design ensures reliable detection of bulk solids and prevents false readings caused by vibration, dust accumulation, or material flow turbulence.
Beam Pitch Options
The sensor is optimized to detect powders and granular materials with particle sizes below 10 mm and densities starting from 0.2 kg/dm³. This wide sensitivity range allows accurate detection of materials such as:
- Cement powder
- Plastic granules
- Grain and flour
- Sand and minerals
- Chemical powders
This flexibility makes the device suitable for a wide variety of industrial applications.
Intrinsic Synchronism
The system is designed with intrinsic safety logic that ensures the sensor returns to a safe state in case of malfunction or power failure. This fail-safe design improves operational safety and helps prevent overfilling or empty silo conditions.
Operational Advantages
Industrial facilities benefit from the GVS25AT due to its robust performance and low maintenance requirements.
Operational benefits include:
- Stable operation in high-temperature environments
- Reduced downtime and maintenance costs
- Reliable switching signal for automated control systems
- Flexible installation in silos, tanks, and hoppers
- Improved safety in bulk material handling processes
This makes the GVS25AT an ideal solution for continuous production environments requiring dependable level monitoring.
