Alliance Sensors Group announces the release of the MR Series of Linear Position Sensors for use in measuring the ram position of hydraulic and pneumatic cylinders.

  • Designed to be a drop-in form, fit and function replacement for magnetostrictive sensors but with much more robust construction and a lower cost of ownership
  • Targeted towards port-mounted applications of industrial, mobile or subsea hydraulic cylinders and large pneumatic actuators
  • Contactless inductive sensing design employs 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 
  • Does not require a magnet
  • Measurement ranges from 1 to 24 in. (100 to 600 mm)
  • Operates to 5,000 psi or 10,000-foot (3,000 m) depth
  • Includes IEC IP-67 aluminum or stainless steel housing
  • Contactless so it will not wear out
  • Features operation to 85 C (105 C option)
  • Provides DC voltage or current analog output
  • Simple coil design ensures ability to withstand intense shocks and vibration
  • Features shorter stroke-to-probe length ratio and can thread into the same o-ring bosses (either SAE J1926-8 or ISO 6149-1 M18) that accept a magnetostrictive sensor
  • Magnet ring can usually be left in place without affecting the performance of the sensor for applications where existing magnetostrictive sensor is being replaced 
  • Delivers linearity error of less than or equal to ±0.1% of Full Scale Output, and a -3dB frequency response of 300 Hz
  • Comes standard with a 4-pin M-12 connector or 5-pin DIN connector, or with a 4-conductor cable, but other connectors and cable options are available
  • IP67 sealed housing uses no trimmer pots for setting Zero and Full Scale
  • SenSet Field Adjustable Scaling calibration feature permits user to match analog output 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
