Inductive Linear Sensor offers Position Feedback in Hydraulic Cylinders

Alliance Sensors Group is pleased to announce the ME Series Linear Position Sensors for embedded use in measuring the ram position of hydraulic and pneumatic cylinders in industrial, mobile, or subsea applications. The ME Series is designed to be drop-in form, fit, and function replacements for embedded magnetostrictive sensors but with much more robust construction and a lower cost of ownership. They can also replace embedded resistance potentiometers, offering high accuracy without wearout. The ME Series sensors are based on a patented contactless inductive sensing technology that uses solid probe construction and 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, counterbored hole, or any other type of special target.

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 aluminium or stainless steel housing
–    Contactless; no wearout
–    85 C operation (105 C option)
–    DC voltage or current analog output
–    SenSet™ Field Adjustable Scaling

ME sensors use a simple coil design rather than “time-of-flight” technology or resistive film. Duplicating the head end of typical embedded sensors, the head of an ME series sensor fits into the same 48 mm diameter cavity as a magnetostrictive sensor or potentiometer fitted into the end housing of a cylinder. For applications where an ME sensor is replacing an existing magnetostrictive sensor, the magnet ring can usually be left in place without significantly affecting the performance of the ME Series sensor.

Besides the ME series embeddable cylinder sensor, Alliance Sensor Group also offers a port mounted version called the MR Series, plus a full line of heavy duty LVDTs and electronics for measuring position in power plants, industrial manufacturing, and process control applications.
