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.

摘要： A magnetic encoder scale (30) comprises a series of periodically spaced magnetic marks. A reference mark (34) is applied to the scale using an applicator or template (32), which has a feature (33) for locating the reference mark. The applicator or template (32) comprises one or more magnetic marks corresponding to the periodic scale marks, whereby the applicator or template automatically assumes a defined phase relationship relative to the periodic scale marks when placed on the scale. The reference mark may be attached to the scale self-adhesively. Or it may be formed by removal of material from the scale, guided by the applicator or template. Or the applicator may comprise a strong permanent magnet which applies further magnetisation to a region of the scale.

摘要： The invention relates to the process and device for adjusting a rotary encoder, i.e. the absolute magnetic rotary encoder with Hall effect sensors which, when positioned in the form of a circle, detect the magnetic field of a diametrically polarised permanent magnet. The rotary encoder adjustment process features the following: the actuator magnet turns once or several times over the sensor circuit, whereby the time-dependant rotation angle is recorded/stored; time-dependant presupposed values of the rotation angle are calculated; these are then subtracted from the measured actual rotation angle values; by analysing the obtained difference, the electric parameter values for the sensor circuit are determined in such a manner as to make the newly measured difference based on new electric parameter values smaller than before the change; the electric parameter values for the sensor circuit are written into the sensor circuit.

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： A scale (10) has magnetic incremental scale marks in a track (10a), and a pseudo-random code sequence in a reference mark track (10b). Sensors (2, 3) feed the pattern of the code in the track (10b) into a bi-directional shift register (18). So that a user can select any desired position for use as a reference mark, a memory (24) is provided, into which any selected code value can be pre-stored. A comparator (26) then compares the code value in the shift register (18) with the code value in the memory (24) and outputs a reference mark signal (Ri) when they match.
