Magnetostrictive linear position sensor
The linear transducers in our MP series operate using transit time measurement between two points of a magnetostrictive waveguide. Displacement is measured by a movable magnet, the distance from the zero point of which corresponds to the segment being measured. The transit time of a transmitted pulse is directly related to this segment and is converted into the measurement signal in the electronics.
The waveguide is protected in a pressure-resistant stainless steel tube or extruded profile, while the electronics are housed in an aluminium housing.
In the MP series transducer, the position magnet is housed in a slider connected to the moving part of the machine. A variation on this is our MS series, where the magnet is housed in a ring that moves contactlessly across the rod.
