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 inch),
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 (0.018 lb/in³). The LVL200
can be used in difficult conditions including turbulence, air bubbles,
foam generation, buildup, or 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 approximately 1 200 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.
The optional signal conditioner provides a remote test feature to
ensure continuous product reliability.
• Key Applications: for use in liquids and slurries, for level measurement, overfill, and dry run protection
