magnetostrictive the sensor of the thermometer is working, the sensor circuit part will inspire a pulse current on waveguide wire, wire when the current wire along the waveguide propagation in the waveguide of impulse current magnetic field generated around. Outside the magnetostrictive sensor rod thermometer with a float, the float along the rod can move up and down along with the change of liquid level. A group of permanent magnetic ring inside the float.

magnetostrictive thermometer is suitable for high precision requirement of clean liquid level measurement, the precision of 1 mm, the latest product has been precision can reach 0. 1mm。 Magnetostrictive thermometer can also be applied to the boundary between two different liquid level measurement. Explosion-proof design, suitable for dangerous situations, intelligent electronic circuit design can calculate the volume; The only moving parts to float, low maintenance cost. Magnetostrictive technology principle is to use two different magnetic fields intersect to create a strain pulse signal, and then by detecting the amount of time required to compute the signal cycle, so as to figure out the exact location. One from the two magnetic field activities to the outside of the sensor magnets, another came from waveguide within the sensor current pulse, and the current pulse is produced by the inherent electronic parts of the sensor head. When two intersecting magnetic field, produced by a strain pulse will run to the fixed speed of sound (back to the electronic components of the sensor coil. From moment to generate an electric current pulse response variable pulse measuring the time required to cycle times the fixed speed, we can accurately calculate the changes in the position of the magnet.
