The MagneRule Plus™ magnetostrictive linear displacement
transducer provides highly accurate absolute position
measurement of displacement up to 120 inches (3 meters).
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 MagneRule Plus™ possesses
exceptional linearity, even over lengths up to 120 inches (3
meters), with repeatability up to 0.002% of the
measurement range. By utilizing magnetostrictive
technology, MagneRule Plus, 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.

Hostile Environments
MagneRule Plus™ operates in hostile industrial
environments with high temperatures and working
pressure. The sensor probe is pressure-sealed with an “O”
ring to operate in hydraulic fluids up to 5000 psi. Integral
electronics are protected against contamination from dust.

Selectable Inputs/Outputs
MagneRule Plus is powered by ±15 VDC or 24 VDC. By
providing an absolute output, no data is lost should power
be interrupted. The long stroke sensor offers a universal
analog position output, as well as a velocity output.
Therefore, one unit can be stocked for multiple
applications.

Easy Installation
The design of the MagneRule Plus™ permits simple
mounting and hookup. Electronics are self-contained in the
sensor head, eliminating the need for additional electronic
packages. For external sensor installation, special mounting
kits and various magnet options are available.
