Courtesy: Alliance Sensors GroupThe MR Series of Linear Position Sensors by Alliance Sensors Group are designed to be a drop-in form, fit, and function replacement for magnetostrictive sensors. MR Series sensors are based on a contactless inductive sensing technology that employs a solid probe construction style which requires only a simple conductive tubular target or a small diameter deep hole gun drilled in the cylinder rod for operation rather than needing a permanent magnet ring or some other type of special target.

Resembling a magnetostrictive sensor with its sensor head and male o-ring port threads, an MR sensor has a shorter stroke-to-probe length ratio and can thread into the same o-ring bosses that accept a magnetostrictive sensor.

MR Linear Position Sensors are available in full ranges from 2 inches to 36 inches (50 mm to 900 mm) with either an analog DC voltage or current output, a linearity error of less than or equal to ±0.1% of Full Scale Output, and a -3dB frequency response of 500 Hz.

The IP-67 sealed housing uses no trimmer pots for setting Zero and Full Scale.  Instead, ASG's proprietary SenSet calibration feature permits the user to match the analog output of the sensor to the motion of the actuator or cylinder on a stand-alone basis rather than the user having to scale the sensor's basic output in an associated control system.
