The SITRANS LVL100 compact level switch can be mounted in small pipes and confined space applications and is also virtually unaffected by the chemical and physical properties of the liquid. The LVL100 can also be used in difficult conditions including turbulence, air bubbles, foam generation, buildup, or strong external vibration. The tuning fork is piezoelectrically energized and vibrates at its mechanical resonance frequency of approximately 1200 Hz. The vibration frequency changes when the tuning fork is covered by the medium. This change is detected by the integrated oscillator and converted into a switching command. The integrated electronics evaluate the level signal and output a switching signal, directly operating connected devices.

Key Applications: For use in liquids and slurries, for level measurement, overfill, and dry run protection.
