Description

Level sensors with a magnetostrictive, high-resolution measuring principle are used for continuous level measurement of liquids and are based on determining the position of a magnetic float following the magnetostrictive measuring principle. The sensors are mounted on the outside of a bypass level indicator. The measuring process is triggered by a current impulse. This current produces a circular magnetic field along a wire made of magnetostrictive material, which is held under tension inside the sensor tube. At the point being measured (liquid level) there is a cylindrical float with permanent magnets acting as a position transducer, whose field lines run at right angles to the impulse magnetic field. This magnetic field of the float tensions the wire. Applications Sensor for continuous level measurement of liquids in bypass level indicators Chemical and petrochemical industries, offshore Shipbuilding, machine building Power generating equipment, power plants Pharmaceutical, food, water treatment, environmental engineering industries Special features Continuous level measurement on the outside of the bypass 2-wire technology 4 ... 20 mA Measured value output via digital interface and a selectable measured value as analogue signal Case from stainless steel (display from glass) Magnetostrictive level measuring instrument with high resolution
