摘要： A method is described for making an encoder scale. In a preferred embodiment, the encoder scale is a piston rod (32) for use in a pneumatic or hydraulic cylinder (30). The method comprises the steps of providing a mask (10) defining a required groove pattern on an encoder scale member (12) that is formed from a first material (e.g. steel) and etching material from the encoder scale member (12), through the mask, to form a plurality of grooves (16) in the outer surface of the encoder scale member (12). A second material such as copper (18) is then deposited on to the encoder scale member (12) to substantially fill the grooves (16), the second material having a different magnetic permeability than the first material. A machining process (e.g. grinding) is then used to remove any excess second material and thereby provide an encoder scale member (12) having a substantially smooth outer surface (20). A step of coating the outer surface of the encoder scale member with a metal, such as chromium (20), is then performed.

摘要： The object of the invention is a magnetic rotary displacement encoder with a protected elasto-ferrite layer. A position encoder is a device that senses a physical change that appears in linear or rotary displacement and translates it to an analogue or digital electrical signal. The encoder of the invention is characterized in that at least over an external wall of a layer (2) of the elasto-ferrite carrier a protective layer (3) made from a non-ferromagnetic material is applied having a thickness of an order of magnitude of 10x smaller than the width of magnetic poles in the elasto-ferrite layer (2), or made from a ferromagnetic material having a thickness of an order of magnitude of 5-10x smaller than the thickness of the layer (3) made from a non-ferromagnetic material.
