Vibrating Fork Level Switch (Swift)

The Vibrating Fork is one of the most reliable solutions for accurate point level detection in both liquids and bulk solids. At Jaycee Tech, we design and supply vibrating fork sensors that deliver precise, maintenance-free performance across diverse industries.

How Vibrating Fork Works

A vibrating fork sensor uses a fork-shaped probe that vibrates at a set frequency. When it comes in contact with material—whether liquid, powder, or granules—the vibration changes, triggering a signal for level detection. This ensures safe, consistent, and reliable monitoring of tanks, silos, and vessels.

A vibrating fork level switch, also known as a tuning fork level switch, is a type of level sensor widely used in industrial applications to detect the presence or absence of bulk solids or liquids in tanks, hoppers, and pipelines. It operates on the principle of mechanical vibration and is highly reliable in detecting and monitoring levels.

The vibrating fork level switch consists of a fork-shaped probe, typically made of stainless steel, with one or two tines. The probe is mounted vertically or horizontally at the point where the level needs to be monitored. The tines of the fork are designed to vibrate at their natural frequency, which is typically in the range of tens or hundreds of Hertz.

When the fork is in air or in an empty condition, it vibrates freely at its natural frequency. However, when the tines come into contact with a solid or liquid material, the vibration is dampened or attenuated. This change in vibration is detected by a piezoelectric crystal or a vibration sensor located in the fork assembly.

The detection of the change in vibration triggers a switching action, indicating the presence or absence of the material at the level being monitored. This switching action can be used to control alarms, indicators, or actuators for various process control or safety applications.

Vibrating fork level switches offer several advantages in level sensing. They are highly reliable, unaffected by changes in material properties such as density, conductivity, or dielectric constant. They are also not affected by external factors like dust, temperature, or pressure variations. Additionally, they have a simple design, are easy to install, and require minimal maintenance.

These level switches are commonly used in industries such as food and beverage, pharmaceuticals, plastics, chemicals, and water treatment. They can be applied to detect high or low levels of bulk solids such as powders, granules, grains, and pellets, as well as liquids with a minimum density.

When selecting a vibrating fork level switch, it is important to consider factors such as the material being detected, the process conditions (temperature, pressure), the required level detection range, and the mounting configuration. Some advanced models may offer features such as adjustable sensitivity, self-diagnostic capabilities, or digital communication interfaces.

In conclusion, a vibrating fork level switch is a reliable and versatile device used for level detection in industrial applications. It offers accurate and consistent performance in monitoring the presence or absence of solids or liquids, contributing to process control, inventory management, and safety in various industries.

Vibrating fork-level switches are crucial products in industrial motor categories that help realise point-level detection in the automatic industrial processes to improve efficiency and safety.
