MLW Series of Long Stroke Linear Position Sensors

MLW Series of Long Stroke Linear Position Sensors

Macro Sensors' MLW Series of Long Stroke Linear Position Sensors are for absolute position measurement of displacements up to 1.2 m. Available in ranges of 300 (11.8) to 1,200 mm (39.4 inch), these contactless linear position transducers are useful for hydraulic cylinder and actuator feedback applications where the sensor can either be mounted externally or embedded into the cylinder or actuator body.

Utilizing magnetostrictive technology, the MLW sensors operate by transmitting a current pulse through its tube that is reflected by a moveable permanent magnet. The sensor measures the time of flight to determine the position of the magnet on the tube. The time-based position measurement is translated into an output signal.

Powered by 24V dc, the MLW Series of Long Stroke Linear Position Sensors have less than +/-0.25 percent linearity and +/-0.01 percent repeatability over the full scale with outputs that include analog voltage, current and SSI. As these magnetostrictive transducers provide absolute output, no data is lost should power be interrupted.

Self contained electronics, a stainless steel probe and die cast probe head with an IP66 rating and tube IP67 make transducers useful for measuring the position of moving machine parts in physically demanding applications such as paper and pulp mills, injection molding machinery, turbine blades and process level management. Construction equipment, automotive test stands, flight simulators and valve position are all commonly instrumented with magnetostrictive sensors.

As the sensor probe is sealed up to 5,000 psi, the MLW sensors can be packaged within hydraulic cylinders as a closed loop feedback device. With an optional float kit for the magnet, the MLW sensors can be used to sense the level of liquid inside of a tank.
