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

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

Powered by 24V dc, the MLW Series of Long Stroke Linear PositionSensors have less than +/-0.25 percent linearity and +/-0.01 percentrepeatability 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 steelprobe and die cast probe head with an IP66 rating and tube IP67 maketransducers useful for measuring the position of moving machine parts inphysically demanding applications such as paper and pulp mills, injectionmolding machinery, turbine blades and process level management. Constructionequipment, automotive test stands, flight simulators and valve position are allcommonly instrumented with magnetostrictive sensors.

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