FAQs of Compact Vibrating Fork Level Switch:
Q: How does the vibrating fork level switch detect fluid levels?
A: The switch utilizes piezo-electric crystals to vibrate its fork; when the forks come into contact with liquid, vibration changes are detected, which then triggers a relay signal for liquid presence or absence.
Q: What types of mounting options are available for this device?
A: This model supports both top and side mounting installations, offering flexibility to suit tank or vessel design constraints in various industrial settings.
Q: Where is this vibrating fork level switch typically used?
A: It is widely applied in the food and beverage, dairy, oil, brewery, and pharmaceutical industries for monitoring levels of fluids such as milk products, edible oil, fuel oil, lube oil, and process fluids.
Q: What is the installation process for the vibrating fork level switch?
A: Installation involves securing the switch using threaded connections at the desired tank or vessel location (top or side). No calibration is necessarysimply connect the universal power supply and integrate with your control system.
Q: What are the benefits of using a cable-free, compact vibrating fork level switch?
A: Advantages include straightforward integration due to compact size, minimal energy usage, versatile voltage acceptance (1580 VDC or 15260 VAC), and the elimination of calibration requirements, reducing operating costs and complexity.
Q: What protection ratings does this level switch offer?
A: Designed with either IP67 or IP68 protection, the switch resists dust ingress and water immersion, making it suitable for rigorous washdown or harsh industrial environments.
