Siemens designed SITRANS LVL200 as a level switch for industrial use across all areas of process technology, and operators can use it with liquids and slurries. With a tuning fork insertion length of just 40 mm (1.57 inch), installers can mount SITRANS LVL200 in small pipes and applications with limited space. Operators can use the LVL200 to measure products having a minimum density of > 0.5 g/cm³ (0.018 lb/in³). They can also use the LVL200 in challenging conditions involving 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.

A piezoelectric mechanism energizes the tuning fork, causing it to vibrate at its mechanical resonance frequency of around 1,200 Hz. When the medium covers the tuning fork, the vibration frequency changes. The integrated oscillator detects this change and converts it 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
