position sensorAlliance Sensors Group (Moorestown, NJ) announced the MR Series of Linear Position Sensors for use in measuring the ram position of hydraulic and large pneumatic cylinders. The MR Series is presented as a drop-in form, fit, and function replacement for port-mounted magnetostrictive sensors, but with more robust construction and a lower cost of ownership, specifically targeting ram position sensing applications in industrial, mobile, or subsea hydraulic cylinders or large pneumatic actuators. MR Series sensors are based on a patented contactless inductive sensing technology that employs a sturdy probe construction requiring only a simple conductive tubular target or a 5/16 inch (8 mm) diameter gun-drilled hole in the cylinder rod for operation rather than needing a magnet ring or other type of special target. Features include:

  • No magnet requirement.
  • Measurement ranges from 4 to 36 inches (100 to 900 mm).
  • Operation to 5000 psi or 10,000 feet (3000 m) depth.
  • SAE J1926-8 or ISO 6149-1 (M18) male o-ring port.
  • IEC IP-67 aluminum or stainless steel housing.
  • Contactless; no wearout.
