The TFS Series from Icon Process Controls is a rugged, compact, and highly reliable vibrating level switch designed for precise detection of liquid and slurry levels in industrial environments. Whether you're monitoring overflow, high or low levels, or safeguarding pumps, the TFS excels in tough process conditions including turbulence, foam, and air bubbles.

At the heart of the TFS is a compact tuning fork sensor with a minimal insertion depth of just 45 mm (1.77"), making it ideal for confined spaces, small tanks, and narrow pipes. The probe vibrates at a fixed frequency, and any change in medium (liquid, slurry, or solid) dampens the vibration, triggering a precise switch response.
