Vibrating Fork Level Switch

The Vibrating Fork Level Switch, also known as a Tuning Fork Level Switch, is an industrial point level switch designed to detect the presence or absence of liquids and bulk solids inside tanks, silos, hoppers, and process vessels. It operates using a vibrating fork driven at its natural resonant frequency by piezoelectric technology.

When the fork comes into contact with the process media, its vibration frequency changes. The built-in electronics detect this change and generate an output signal for alarms or automatic process control. This simple yet highly reliable operating principle provides accurate level detection without requiring calibration.

The Vibrating Fork Level Switch is widely used for high-level alarms, low-level alarms, overflow protection, and automatic filling or emptying control. It is suitable for water, solvents, chemicals, food & beverages, and various bulk solid materials, making it ideal for oil & gas, chemical processing, food processing, pharmaceutical, water treatment, cement, and many other industrial applications.
