Magnetostrictive linear motion sensors TWK-ELEKTRONIK MPK/MSK series they have a non-contact sensor system, which indicates a high operating life. TWK-ELEKTRONIK MPK/MSK series magnetostrictive linear displacement sensors operate on the principle of measuring the passage time between two positions of a magnetostrictive waveguide. The first position is determined by a moving positional magnet, the distance of the segment of which must be measured. The pulse travel time is directly proportional to the distance of the segment. The waveguide is built into a pressure-resistant stainless steel cylinder. The rear part of the sensor structure is mounted in a die-cast aluminum housing, inside of which there is an electronic filling. In the "core" design, the positional magnet is located in a ring, which is located along the rod without contacting it. In the profile design, the positional magnet is located in the motor, which is fixed to the moving element of the device through a hinge joint.
Magnetostrictive sensors TWK-ELEKTRONIK MPK series are equipped with a profile design, sensors of the MSK series have a rod design, these sensors are also capable of measuring data from 5 positions, an EtherCAT interface is used to work with sensors of this type.
