Abstract: A sealed encoder module for mounting onto a machine so as to measure relative displacement of first and second parts of the machine. The sealed encoder module can comprise, a scale, a readhead comprising a scale signal receiver, and an integral protective housing which encapsulates at least the scale and said scale signal receiver. The sealed encoder module can be configured to determine and output diagnostic information regarding a scale signal detected by the readhead.

Abstract: An apparatus including an encoder scale disc and a mount, the encoder scale disc including radially and/or tangentially resilient features located radially outwards of a scale configured to interact with the mount so as to locate the scale disc on the mount. The encoder scale disc may include radially resilient features which may deviate radially from the disc. A method of manufacturing an apparatus including an encoder scale disc, including mounting a disc including radially resilient features to a device, wherein the radially resilient features of the disc interact with the device to place the disc in radial compression, mounting the disc on an apparatus, wherein mounting features on the device and the apparatus interact in the same manner to place the disc in radial compression.

Abstract: A method of mounting rotary scale member on machine part includes: locating rotary scale member on machine part such that scale axis and axis of rotation are substantially parallel, and subsequently arranging at least a first radial adjustment device to contact both machine part and rotary scale member, and manipulating the at least first radial adjustment device to radially displace body of rotary scale member. At least the majority of any radial reaction force, generated as a result of the interaction of at least one of the flexures with a radial stop member against which it is radially pressed, and which is imparted on the at least first radial adjustment device by rotary scale member in opposition to the radial displacement of the rotary scale member, is directed into, and reacted by, the machine part via the contact between the at least first radial adjustment device and the machine part.

Abstract: A method of mounting a rotary scale member on a part, the rotary scale member including a body on which a series of position features defining a scale is provided, and at least one mounting flexure configured to engage the part, the method including: force-fitting the rotary scale member and the part together, whereby the at least one flexure is displaced by the part and thereby urged via a radial reaction force into engagement with the part so as to form a friction fit with the part such that the body of the rotary scale member self-locates at an initial default radial location with respect to the part; and tweaking the radial location of the body relative to the part away from its initial default radial location to a new radial location.

Abstract: An encoder apparatus comprising a scale and a readhead assembly comprising a scale signal receiver. The scale and the scale signal receiver are located within a protective housing which is configured to protect them from contamination located outside the protective housing and comprises a seal through which the scale signal receiver can be connected to a part outside the protective housing. The arrangement of the scale signal receiver inside the protective housing is independent of the scale and protective housing.
