series working on the
magnetostrictive principle are suitable for high accuracy level measurement
of storage tanks. Due to their high temperature and pressure rating these
units can also be used for level gauging of technological tanks. The 2-wire
magnetostrictive level transmitters are an ideal solution for high accuracy
measurement of clean fluids.
Operating principle
The magnetostrictive transmitter is using the special feature of the
magnetostrictive wire spanned in the rigid probe. A magnetic field excited in the
magnetostrictive wire develops an acoustic wave in the wire. From the
interference point with the magnetic disc placed in the float the wave travels
back to the electronics with defined velocity. Measurement is based on the time
of flight of the acoustic wave since it is proportional with the distance of the float
from the electronics.
The above distance constitutes the basis for all output signals of the
NIVOTRACK! With the help of further mechanical data level can be calculated.
