ME and MR Series Inductive Linear Position Sensors for Hydraulic Cylinders

Press release date: July 11, 2014

MOORESTOWN, NJ --- Alliance Sensors Group is pleased to announce the continued success of the ME and MR Series Linear Position Sensors used to measure the ram position of hydraulic and pneumatic cylinders in industrial, mobile, or subsea applications. With NO MAGNET REQUIRED the installation and cost of ownership is dramatically reduced without sacrificing accuracy specifications. The ME (embedded version) and MR (port-mount version) Series fit into a gun-drilled cylinder in the same way a magnetostrictive sensor would be installed but without the counterbore necessary for the magnet.

Features:
- NO MAGNET REQUIRED !!!
- Measurement ranges from 4 to 36 inches (100 to 900 mm)
- Operates to 5000 psi or 10,000 feet (3000 m) depth
- IEC IP-67 aluminum or stainless steel housing
- Contactless; no wearout
- 85 C operation (105 C option)
- DC voltage or current analog output
- SenSet™ Field Adjustable Scaling

ME/MR sensors use a simple coil design rather than “time-of-flight” technology or resistive film. They are based on a patented 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. The ME/MR Series sensors can withstand intense shocks and vibration, and operating temperatures up to 85 C for standard products and 125 C for custom units. Resembling a magnetostrictive sensor with its sensor head and male o-ring port threads, an ME/MR sensor has a 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.  For those applications where an ME/MR is replacing an existing magnetostrictive sensor, the magnet ring can usually be left in place without affecting the performance of the sensor. 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.
