Tuning Fork Level Switch NS210 | Universal Liquid & Solid Level Limit Switch
- Brand：NOIKE-AH
- Model：NS210
Specification
Product Overview
The Tuning Fork Level Switch NS210 is a universal level limit switch designed for reliable point level detection of both liquids and bulk solids. It operates using a piezoelectric crystal that excites the tuning fork into vibration. When the fork is immersed in liquid or covered by solid material, the vibration frequency changes. This change is detected electronically to generate a switching signal.
The measuring principle is not affected by dielectric constant, turbulence, agitation, bubbles, vibration, or other process disturbances, making the NS210 suitable for complex industrial applications.
With no moving mechanical parts, the NS210 requires minimal maintenance and provides stable long-term operation in demanding environments.
Why Choose the Tuning Fork Level Switch NS210 ?
Selecting the right level switch is essential for improving process reliability and reducing maintenance.
The NS210 offers a vibration-based measuring principle that is suitable for both liquid and solid level detection without requiring calibration for different media densities or electrical properties. Its maintenance-free design, relay output, optional AC/DC power supply, and corrosion-resistant stainless steel wetted parts make it a practical solution for industrial process control.
