Vibratory switches

The Sitrans LVL100 and LVL200 vibratory switches from Siemens are suitable for high and low detection of all liquid media, independent of mounting position.

The compact switches measure reliably in changing conditions, such as variations in the dielectric permittivity of a medium or the formation of vapour or bubbles. The switches are used in storage and process applications and can be connected to any signalling systems. They are insensitive to external vibrations and have a long service life. Both switches are equipped with a reliable piezo actuator and are suitable for high temperatures. If the electronics detect damage or corrosion, the fail-safe switches trigger an alarm.

Sitrans LVL100 is suitable for applications where space is limited, for pressure vessels and for protection against running dry. Due to its compact design, the switch can be mounted vertically, horizontally or inclined. It is suitable for all pipelines with a nominal diameter of DN25 and above.

In compliance with SIL2, Sitrans LVL200 has a safety shutdown for detection of minimum/maximum levels. The switch operates reliably in temperatures up to 250°C.
