Versatile and Durable ConstructionConstructed from high-quality mild steel and stainless steel with a polished finish, the tuning fork level switch offers long-term resistance to mechanical stress and corrosive environments. Its orange-silver color coding ensures easy identification during installation and maintenance in industrial facilities.
Advanced Sensing and Safety FeaturesThis level switch operates at a vibration frequency of approximately 400 Hz, providing precise switching at up to 50Hz. Field-selectable fail-safe mode (empty/full) and IP67-rated protection ensure device stability even in demanding process conditions. The SPDT relay output enhances compatibility with automation systems.
Customizable and Easy to InstallWith process connections in threaded (1 BSP/NPT) or flanged formats and customizable lengths, the device is easily adaptable to various tanks and silos. Cable entry is facilitated by PG9 or PG13.5 glands, and single-pole circuitry simplifies integration. The switch is suitable for use in temperatures ranging from -40C to +80C.
FAQ's of Tuning Fork Level Switch:
Q: How does the tuning fork level switch detect material levels in tanks or silos?
A: The tuning fork level switch uses vibrating prongs that sense the presence or absence of material (liquid, slurry, or solid) with a density above 0.7g/cm3. When the fork is covered or uncovered by the process medium, the vibration dampens or resumes, which the device translates into a switching signal.
Q: What process connections are available for this level switch, and where can it be installed?
A: This device is offered with both threaded (1 BSP/NPT) and flanged process connections, making it versatile for installation in various tanks, vessels, or silos across industrial plants. The design also allows for flexible mounting orientations based on site requirements.
Q: When should I select the fail-safe mode and how is it configured?
A: Fail-safe mode can be set to either 'empty' or 'full', depending on whether you want the switch to indicate an alarm during loss of power when the vessel is empty or full. The mode is field-selectable, allowing configuration during installation according to safety and process needs.
Q: What are the main benefits of using this tuning fork level switch for level detection?
A: The main advantages include high reliability due to minimal moving parts, precise and rapid response time (<1 second), and suitability for a wide density range of media. The unit's long mechanical life (>10 million operations) and robust IP67 protection ensure minimal maintenance and extended operational life.
Q: How should the device be wired and what power supply options are available?
A: The switch supports relay outputs (NO+NC) with SPDT configuration, suitable for both AC and DC operation at 24V DC, 110V AC, or 230V AC. It features a cable entry via PG9 or PG13.5 glands for secure electrical connections. Wiring diagrams are provided by the manufacturer for correct installation.
Q: What types of applications is this level switch suitable for?
A: It is designed for use in level detection and control of liquids, slurries, and free-flowing solids in industries such as water treatment, food and beverage, chemicals, and bulk material handling, providing accurate monitoring even under harsh conditions.
