Sick  is presenting the LFV200, a compact limit level sensor with a vibrating fork, at the Hanover Trade Fair 2008.

The device is suitable for detecting liquids in storage tanks and pipes. In addition to a version for factory automation, the LFV200 is also available in a hygiene-oriented design for use in the food, beverages and pharmaceutical industries.

The LFV200 has been designed as a vibrating limit switch and can thus detect filling levels in tanks and pipes regardless of medium properties such as density, viscosity or dielectric constant.

The sensor’s highly compact piezoelectric-driven vibration element vibrates at its mechanical resonance frequency.

Neither heavy vibrations from other sources nor changes in the filling medium impair the reliable function of the LFV200.

The frequency changes when the vibrating fork is covered or uncovered by the medium – depending on its function, used as a maximum or minimum value provider. The LVF’s electronics unit detects this and generates a switching signal via the transistor switching output.

Integrated monitoring of function
The LFV200’s electronics are accommodated in a rugged stainless steel housing. The connection thread is either ¾ or 1 inch.

The vibrating fork is made of stainless steel. In the food version, it is polished and thus offers the reduced roughness necessary for this use. At the same time, this version has tri-clamp connections and milk pipe screws in compliance with DIN 11851.

The LFV200 thus offers the necessary sturdiness for the particular application – especially as the sensor is specified for process temperatures of from -40°C to +150°C.

Supplements Sick’s filling level product portfolio
The LFV200 is the optimum supplement for the LFT filling level measurement system, as well as for the entire range of filling level measurement technology from Sick. Depending on the application, the optimum solution can be selected from the various products available.
