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.

GYSE-R-PF Probe

High accuracy type
( detachable probe element )

This is the linear profile version of GYSE-R. Between probe and controller, RS-422 differential line driver transmission, providing robustness against electrical noise, is used. In combination with a digital output controller, Min.1μm resolution is possible. The inside probe elementcan be detached from the outer housing. And by auto calibration function, a difference in the output when you change the probe is adjusted automatically.

◆Associated controller

• Analogue output: GYHC
• Digital output: GYDC-S1, GYDC-05
• IRDS-GY: When using the IRDM, you can connect with CC-Link, CC-Link IE Field, PROFIBUS, EtherNet/IP, and EtherCAT.
• DC-Q: MELSEC-Q built-in unit
