Application SITRANS LVL100 is a compact level switch designed for indus-trial use in all areas of process technology and can be used with liquids and slurries. With an insertion length of only 40 mm (1.57“), SITRANS LVL100 can be mounted in small pipes and confined space applications. It 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 bub- bles, 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 cov- ered by the medium. This change is detected by the integrated oscillator and converted into a switching command. The inte-grated electronics evaluate the level signal and output a switch-ing signal, directly operating connected devices.•Key Applications: For use in liquids and slurries, for level mea-surement, overfill, and dry run protection
