While many sensors, especially those based on microelectromechanical systems (MEMS) technology, get increasingly smaller, some measurements dictate the need for a large or sufficiently long sensor. This is the case when measuring the position of moving machine parts in applications such as paper and pulp mills, injection molding machinery, turbine blades and process level management. These are the types of applications addressed by a new series of sensors from Macro Sensors. The MLW Series of Long Stroke Linear Position Sensors are designed for highly accurately absolute position measurement of displacements up to 1.2 meters.
The sensors use magnetostrictive technology and operate by transmitting a current pulse through a tube that is reflected by a moveable permanent magnet. The output signal is based on a time of flight measurement by the sensor that determines the position of the magnet on the tube.
