Operation
Section 3: Operation
The Magnetostrictive Level System is used for accurate and
repeatable measurement of linear motion and liquid level.
All of the sensor's electronics are integrated into the probe.
Magnetostrictive technology uses a float with an embedded
magnet that travels along the 5/8-inch diameter tube. Inside
the tube is a wire that is pulsed with a current that travels down
the wire. As the current pulse intersects the magnetic field of
the float, a reflection creates torsion on the wire that is sensed
by electronic module providing a linear 4-20 mA output.
The instrument needs only to be installed and fixed in position.
There are no adjustments or calibration. The sensor is a fixed
length. Scaling or offset is done in the customer's process
