摘要： An error correction system is disclosed which includes an error correction profile element which extends in a measuring direction inside a housing which contains a measuring scale. The disclosed error compensation system is used to compensate for guidance errors of machines or division errors of the measuring scale. The correction profile element is made as a one piece element having regions of reduced cross sectional area. The profile element is mounted to the housing by means of eccentrics which can be used to adapt the contour of the correction profile element to correspond to the error to be compensated. The error correction profile bends at the regions of reduced cross sectional area while retaining a rectilinear profile in the intermediate regions between the regions of reduced cross sectional area such that a smooth transition is provided between the intermediate regions.

摘要： An encapsulated measuring device is described which includes a hollow body, a scale defining a measuring direction, and a sensing unit disposed to move along the scale within the hollow body. An entrainment member is pivotably secured to the sensing unit and extends out of the hollow body. Sealing members provide a seal between the movable entrainment member and the hollow body, and these sealing members protrude beyond the hollow body so that liquid in the hollow body can flow down onto the sealing members and out of the hollow body through openings between the sealing members and the entrainment member. Because the pivotable articulation allows the entrainment member to be adjusted with respect to the sensing unit, the angle at which the entrainment member protrudes from the hollow body may be adjusted according to the requirements of the individual installations. The configuration of the sealing members allows fluid to drain from the hollow body for a range of orientations of the entrainment member.
摘要翻译：描述了一种封装的测量装置，其包括中空体，限定测量方向的刻度，以及设置成沿着中空体内的刻度移动的感测单元。夹带构件可枢转地固定到感测单元并延伸出中空体。密封构件在可动夹带构件和中空体之间提供密封，并且这些密封构件突出超过中空体，使得中空体中的液体可以通过密封构件之间的开口向下流到密封构件上并且从中空体流出中空体和夹带成员。因为可枢转的关节允许相对于感测单元调节夹带构件，所以可以根据各个装置的要求来调节夹带构件从中空体突出的角度。密封构件的构造允许流体从中空体排出用于夹带构件的一定范围的取向。

摘要： There is provided a linear displacement measuring apparatus which notifies a user when being installed defectively. A slider includes a traveling body which travels along a main scale on the main scale, a carriage part mounted on an object, and coupling means which couples the traveling body with the carriage part. The coupling means allows relative displacement between the traveling body and the carriage part and biases the traveling body towards the main scale. The coupling means has a connecting rod arranged so as to couple the traveling body with the carriage part via a ball joint. The slider further has misalignment detecting means which detects that the relative displacement between the traveling body and the carriage part exceeds a prescribed allowable range. The misalignment detecting means is a pair of projecting pieces arranged in a vicinity of the connecting rod so that the displacement of the connecting rod is regulated within a predetermined range.

摘要： A double ball-bar measuring system includes a calibration unit, at least two double ball-bars and a measuring module. Among the double ball-bars, at least one is a measuring double ball-bar and at least one is a reference double ball-bar. The measuring double ball-bar is installed on a measurement apparatus to measure or calibrate a target machine. The reference double ball-bar is disposed on the calibration unit to measure thermal errors. When the target machine is driven for measurement or calibration, the geometric and thermal errors of the measuring double ball-bar are compensated so that the measurement apparatus can achieve highly accurate measurement.

摘要： A linear encoder includes a plate-type scale and a head which moves along the longitudinal direction of the scale. The scale has graduations formed on a surface of the scale and arranged along the longitudinal direction of the scale. The head includes a reading part which detects an amount of a relative movement of the head with respect to the scale by reading graduations formed on the scale. The head includes four bearings each having a rotation axis extending along the transverse direction of the scale. Each of the bearings is situated on the head so as to abut against a surface of the scale, to function as a spacer to maintain a distance between the scale and the head. The scale acts as a plate member interposed between the reading part and the graduations.

摘要： The present invention relates to an encoder readhead. The readhead includes a housing having an opening for capturing an encoder scale including an elongate rod having a substantially circular cross-section, the opening defining an axial direction along which a captured encoder scale can slide back and forth. A scale reader, which may include an array of Hall sensors, is provided for reading a portion of an encoder scale located in the opening. The housing includes an access portion that allows the encoder scale to be inserted into, and/or removed from, the opening by a relative movement between the housing and the encoder scale in a direction other than the axial direction.

摘要： An arrangement for fastening a support of a scale of a linear measuring device on a mounting surface of an object to be measured. The arrangement includes a clamping jaw and a force-exerting element urging the clamping jaw against the support. The clamping jaw acts together with the support in such a way that the clamping jaw urges said support with a clamping force that includes 1) a first force component against the mounting surface by the force-exerting element and 2) a second force component that urges the support against an attachment face extending transversely to the mounting surface. The attachment face is directly constituted by an attachment body, which can be fixed positively and free of play in a receptacle on the object to be measured.
