BFK-LA303/LC303 Level Switch Product Introduction
Product Overview
The BFK-LA303/LC303 level switch series is an intelligent material detection device engineered for industrial process control. Featuring modular design and advanced sensing technology, it accurately monitors solid particles, powders, and liquid levels. The LA303 model with 316L stainless steel probe excels in high-temperature/pressure environments, while the LC303 variant with ceramic-based sensor is optimized for corrosive media. Both models demonstrate exceptional stability in challenging industrial applications with anti-clogging and wear-resistant properties.
Technical Specifications
Operating on contact measurement principle, the devices detect material presence through mechanical vibration frequency shift. The built-in temperature compensation system automatically corrects measurement deviations from -40℃ to 200℃. With IP67 protection rating and 200-400Hz vibration range, they effectively prevent false triggering caused by material buildup. The 5-level sensitivity adjustment knob and dual-channel relay outputs (NPN/PNP compatible) ensure flexible configuration.
Application Fields
Widely implemented in cement plant raw material silos, coal bunker protection for thermal power stations, and chemical processing tank interlock systems. Particularly effective in high-temperature kiln dust collectors, gypsum powder silos with consolidation tendencies, and plastic pellet storage vessels with electrostatic adhesion. Seamless integration with DCS/PLC systems enables automated material handling through level alarm triggering and conveyor control.
Key Advantages
- Self-adaptive calibration: Intelligent algorithms automatically recognize media characteristics
- Modular configuration: Quick-release probe structure supports 3 standard lengths (150/300/450mm)
- Enhanced protection: Dual-layer epoxy encapsulation ensures reliability in humid/dusty environments
- Visual status indication: Tricolor LED ring provides real-time power/alarm status visibility up to 10 meters
Installation & Maintenance
Offers flange/thread mounting options for horizontal or vertical installation. Routine maintenance every 6 months (sensor cleaning with soft cloth) maintains optimal performance. Built-in self-diagnosis monitors probe wear, triggering early warning when sensitivity decreases by 15%.
