Magnetostrictive Displaiacement Transducer

Model GY Series are “Displacement Transducers” employing magnetostrictive phenomena, especially the Wiedemann effect. An ultra-sonic wave is generated by a moving magnet operating near a magnetostrictive wave guide on which the sonic wave propagates up to the head of the transducer.
The propagation time is precisely measured by state of the art technology and then the absolute displacement transducer is operational.

[ Principle ]

The figure shows the fundamental principle of operation.
When a current pulse like A is given to the wave guide, it generates a circumferential magnetic field on the wave guide, then placement of the movable magnet (polarized axially) as shown, only the axial magnetic field of the magnet affecting the wave guide produces a resultant field as indicated by the dotted line.
The vector combination of these two fields produces torsional strain, a phenomenon known as the Wiedemann Effect.
It is a form of vibration and propagates along the wave guide in the form of a transverse ultra-sonic wave.
The GY series displacement transducers detect the propagation time of the ultra-sonic wave.

GYDC-05 Controller

High accuracy digital output
(Parallel, SSI, A/B pulse)

GYDC-05 controller enables digital output of 1μm resolution and also analogue output of the position or the velocity (option). With option, SSI output and the incremental output (A/B pulse) are available.
And putting 2 pcs magnets on one probe and detecting each magnet position or relative distance between 2 magnets are possible. It has toggle switches on front face for zero/gain adjustment, mounting with DIN rail. With the captive software (GPM), zero and gain adjustment is possible at user side.

• CE marking
• Noise cancellation
• GPM setting

◆Auto-calibration
In combination with the probe (GYMR6, GYSE-R, GYKMR, GYRHP-MR6) having auto calibration function, a difference in the output when you change the probe is adjusted automatically.

Specifications

• The above mentioned accuracy applies to sensors with an effective stroke of 300mm or more.
• The specification of stroke less than 300mm is equal that of stroke 300mm.
