The OVFL series fork level switch operates by detecting changes in vibration frequency as the fork is immersed in liquid. When the fork is covered, the vibration frequency changes, triggering a switch. Advantages include reliable, maintenance-free operation, no moving parts, and suitability for a wide range of liquids.
The OVFL series fork level switch is a reliable and versatile device designed to detect the presence or absence of liquids or solids in various industrial applications. Utilizing a fork-shaped sensing element, this switch operates based on the principle of vibrational frequency changes, providing accurate and dependable level detection. Its robust construction and immunity to environmental influences make it suitable for challenging conditions, ensuring optimal performance in a wide range of materials, including corrosive and viscous substances.
The OVFL series fork level switch is used in many industrial and commercial installations, including the following:
Pump control in wastewater treatment
Level control in silos and tanks
Tank level monitoring
Level detection in reservoirs
Chemical storage tanks
Fuel storage tanks management
