MR Series of Linear Position Sensors is suitable for measuring the ram position of hydraulic and pneumatic cylinders. Units are designed to be a drop-in form, fit, and function replacement for magnetostrictive sensors, but with much more robust construction.

 

They specifically target port-mounted applications of industrial, mobile, or subsea hydraulic cylinders and large pneumatic actuators. MR Series sensors are based on a unique contactless inductive sensing technology that employs a solid probe construction style requiring 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.
