Accurate level monitoring is essential in industrial processes to ensure operational efficiency, product quality, and process safety. Whether handling liquids, powders, granules, or bulk solids, selecting the right level switch can significantly improve process reliability.
The ELT Series Vibrating Level Switches are designed to provide dependable point level detection in a wide range of industrial applications, offering robust performance even under challenging process conditions.
How Does a Vibrating Level Switch Work?
Vibrating level switches operate using a piezoelectric-driven vibrating fork or rod. Under normal conditions, the sensor vibrates at its natural resonance frequency. When the process material comes into contact with the sensing element, the vibration frequency changes significantly.
The electronics continuously monitor this frequency. Once a predefined threshold is reached, the device switches its output, indicating the presence or absence of material.
This principle allows reliable level detection regardless of conductivity, dielectric constant, color, or other material properties.
