The tuning fork level switch is a highly reliable liquid level detection device that uses crystal excitation to generate stable fork vibrations. When immersed in liquid, the vibration frequency shifts, and the built-in electronic circuit converts this change into an accurate switch signal. Unlike traditional float switches, the tuning fork level switch is resistant to turbulence, bubbles, agitation, and vibrations, ensuring precise liquid level measurement in challenging environments. With no moving parts, it requires zero maintenance, making it an ideal choice for industries such as chemical processing, petroleum, food, and wastewater treatment where durability and accuracy are critical.
