Operating Principle

The Capacitive Level Switch NS280 operates using intelligent frequency scanning technology.

The sensor continuously scans and analyzes changes in capacitance at the sensing tip. When the measured medium comes into contact with the sensing surface, the dielectric characteristics change, causing the sensor to detect the presence or absence of material.

The intelligent electronic circuit processes the frequency variation and accurately determines the switching point, providing stable point level detection while minimizing the influence of environmental changes.

This measurement principle enables reliable operation across various media while maintaining excellent repeatability and fast response.
