LS210 Tuning Fork Level Switch - Technical Specifications (English Translation)‌

Brand:‌ Shanghai Zanke Automation Co., Ltd.

Model:‌ NS210

Product Description‌

The LS210 tuning fork level switch is a universal device for liquid/solid level detection. Its fork vibrates when excited by a piezoelectric crystal, and the frequency shifts upon immersion in liquid or contact with solids. This change is detected by electronic circuits, ensuring reliable operation unaffected by medium conductivity, turbulence, bubbles, or vibration. With no moving parts, it requires zero maintenance or adjustment, making it ideal for complex industrial conditions.

Key Features‌

No moving parts‌: Maintenance-free design.

Media-independent‌: Unaffected by density or electrical properties of the medium (stainless steel wetted parts).

Flexible power options‌: AC/DC compatible.

Relay output‌: Configurable NO/NC contacts.

Dual applications‌: Suitable for both liquid and solid level detection.

Two housing variants‌: Compact or rugged electronic head options.

Applications‌

Hydraulic/lubrication systems

Pump protection

Cooling systems

Pulp/water treatment

Food & beverage industries
