D-FW 410
Dust filter leak detector
The D-FW 410 is a highly reliable dust filter leak detector designed for monitoring filter leaks in real time. Cost-effective and low maintenance, it has been developed to continuously measure solid particles in a gas flow.
Technology: Triboelectric principle
Benefits
- Accurate detection
Measurement range with detection as low as 0.01 mg/m³, ideal for precise dust emission monitoring - Fast response to process changes
Provides immediate feedback on shifts in dust levels, allowing rapid intervention - No sample handling required
Direct in-duct monitoring streamlines installation and reduces maintenance - Low-maintenance design
Real-time monitoring with practically no drift ensures reliable performance and minimal upkeep - Long-term trend monitoring
Supports ongoing analysis of dust levels for efficient process control and preventive maintenance - Built for harsh environments
IP66 rating - Early filter leak detection
Rapid response to dust level changes helps prevent significant emissions, supporting compliance and avoiding product loss - Improved process efficiency
Continuous, real-time data on dust trends allows for optimized filtration cycles, which improves equipment longevity and reduces downtime - Cost-effective maintenance
Early detection of filter wear or failure minimizes the need for emergency repairs, and preventing costly disruptions promoting efficient maintenance - Environmental and operational responsibility
Accurate monitoring and control of emissions help industries meet environmental standards and improve overall plant efficiency
Applications
- Filter leak detection and dust arrestment plant management
Ideal for monitoring industrial filtration systems such as baghouses, cyclones, and exhaust ducts, where precise dust emission control is required - Process control and trend monitoring
Used in various industries to maintain filtration efficiency, prevent product loss, and monitor system disruptions such as ventilation interruptions or cleaning cycle issues - Broad industry suitability
Suitable for sectors requiring dust control and safety practices, such as cement, metalworking, food processing, chemical manufacturing, etc.
