Application SITRANS LVL200 is a level switch designed for industrial use in all areas of process technology and can be used with liquids and slurries. With a tuning fork insertion length of only 40 mm (1.57“), SITRANS LVL200 can be mounted in small pipes and applications with confined space. The LVL200 can be used to measure products with a minimum density of >0.5 g/cm³ (0.018lbs/in³). The LVL200 can be used in difficult conditions in-cluding turbulence, air bubbles, foam generation, buildup, or strong external vibration.SITRANS LVL200 continuously monitors faults via frequency evaluation, providing early detection of strong corrosion or damage on the tuning fork, loss of vibration, or a line break to the piezo drive.The tuning fork is piezoelectrically energized and vibrates at its mechanical resonance frequency of approx. 1200 Hz. The vibra-tion 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 elec- tronics evaluate the level signal and output a switching signal, directly operating connected devices.•Key Applications: For use in liquids and slurries, for level mea-surement, overfill, and dry run protection
