4 KSR Magnetostrictive Level Transmitters Type FFG-T-... are used for continuous, remote liquid level measurement and based on position monitoring of a magnetic float following the magnetostrictive principle. The measuring process is initiated by a current impulse. This current generates an axial magnetic field (3) along the length of a wire (1) made of magnetostrictive material, which is held under tension inside the guide tube. The float, which sits on the liquid surface, is fitted with permanent magnets (4). When the pulse reaches the float the two magnetic fields interact and a torsional force results. A torsional stress wave (5) is induced in the wire. A piezoceramic converter in the transmitter housing (2) at the end of the wire converts this into an electrical signal. By measuring the elapsed transit time, it is possible to determine the start point of the torsional stress wave and therefore the float position with a high degree of accuracy. Technical advantages The simple and effective principle of operation makes these devices ideally suited for a plethora of applications. Constant measurement of liquid levels, independent of physical and chemical changes of the medium, such as: foaming, conductivity, dielectric constant, pressure, vacuum, temperature, vapours, condensation, bubbles, boiling effects, S.G. changes. Signal transmission over long distances. Simple installation and commissioning - oneoff initial calibration adjustment, no further calibration necessary. Interface and total level measurement at -S.G. 50 kg / m 3. Application limits: T = 200 C to +200 C P = vacuum to 100 bar ρ 400 kg/m 3 Availability of many corrosion resistant materials facilitates use in applications in all industry sectors: chemical, petrochemical, oil and gas, pharmaceutical, off-shore, ship building, power plants, manufacturing, water treatment, food and beverages. Application specific designs and solutions available. Explosion-proof designs. ➀ ➂ ➄ ➃ ➄ ➀ Wire ➁ Electronics housing ➂ Magnetic field ➃ Magnet ➄ Torsional wave
