29 ( 52 )
6.10
Eddy current sensor (SGS, optional accessory)
Order number
1-001
6.10.1
Measurement principle
The displacement measurement system operates without contact on the basis
of an eddy current.
An electromagnetic coil field induces eddy currents and this causes the resis-
tance of the built-in coil to change.
q
An electrical signal is produced from this change.
q
The controller conditions the signal ready for the user.
