Magnetostrictive level sensor for siliceous sand

KunLun Magnetostrictive Probe is designed based on magnetostrictive theory. The

electronic parts of the probe produce a low-voltage electric current "inquiring" pulse, at the same time the pulse produces a magnetic field which travels downwards along the waveguide. Because there are a group of magnets which also produce a magnetic field inside the floater which is moving up and down with the change of the liquid level, there are two magnetic fields in the probe. When two magnetic fields meet, the waveguide will twist and one wave will be produced, we call it the "returning" pulse. Then the electronic parts detect the cycle from producing the pulse of "inquiring" to receiving the pulse of "returning", i.e. the corresponding accurate change of liquid level. Installing temperature sensors inside the probe can make it detect and transfer the liquid temperature continuously at the same time.
