METHOD FOR CONTACTLESS DIGITAL MEASURING OF THE DISPLACEMENT OR POSITION OF A MOVABLE PIECE |
摘要 |
A method for manufacturing a device for contactless and digital measurement of a linear or angular condition of a first piece with respect to a second piece. A series of ferromagnetic encoding marks are provided onto a non-magnetic substrate of one of the pieces. The encoding marks are produced by a strongly local heating of the surface of a non-magnetic substrate of an austenitic steel stabilized by a metalloid in interstitial solution. Displacement, speed and acceleration of a linear or angular kind of one piece with respect to a second piece can thereby be measured with great accuracy.
