The intelligent limit switch for all kinds of liquids

The vibrating level switch of the LFV200 product family detects the pre-defined levels in liquid systems with maximum precision. Whether indicating that a container has reached its maximum fill level (overfill protection) or that it is empty or used in pipes to prevent the pumps from running dry, the LFV200 works with all liquids and is wear- and maintenance-free. A high surface quality and the rugged tuning fork made of stainless steel make the LFV200, in combination with aseptic process connections, the first choice for applications even with the strictest hygiene requirements. With the LFV230, extended pipe variants up to 1,200 mm are available. With IO-Link, the oscillation frequency, amplitude and temperature of the sensor can be read out in addition to the switching signal, which enables extended diagnostics and predictive maintenance.
