Sensors & Instrumentation - Linear Displacement - Magnet Rulers


Magnet ruler are supplied to measure from 150mm to 3050mm with non-linearity of better than ±0.05% of FSD and very high repeatability of ±0.002%.
Since the G series was introduced only a single output is provided, the choice of voltage, current, SSi or Modbus.

Kang YU series MRU
The METRIKEMP™ magnetostrictive linear displacement transducer provides highly accurate absolute position measurement of displacement up to 120 inches (3 meters). This series maintains the order coding followed with the MS Schaevitz MRU family. These models will terminate as the new KYDM series dominates.
The sensor also measures velocity, giving feedback of both position and velocity simultaneously. Operation is based on accurately measuring the distance from a predetermined point to a magnetic field produced by a movable permanent magnet. The design and durability of the sensor make it ideal for measuring position of moving machine members.
Excellent Performance
A marked improvement over potentiometers for long stroke position measurement, the METRIKEMP™ possesses exceptional linearity, even over lengths up to 120 inches (3 meters), with repeatability up to 0.002% of the measurement range. By utilising magnetostrictive technology, METRIKEMP, requires no contact between parts that cause friction or premature wear, offering high reliability and extended life. Good stroke-to-length ratio provides for a more compact long stroke position sensor.
Universal Analog Outputs
METRIKEMP™ translates this time-based position measurement into an analog output signal. A user selectable 0 to 10 VDC voltage (either low or high frequency response) or a 4-20 mA current (3-wire) output is available in either forward or reverse slope signals. Additionally, velocity of the moving magnet ring (up to 10 in/sec) is generated by differentiating the position signal.
