MR Series of Linear Position Sensors Don't Require Magnets
Description
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.
