Abstract: A scale arrangement is designed for monitoring relative displacement between first and second members. The scale arrangement comprises an elongated scale having end portions at both ends thereof, a pair of receptacles respectively receiving the end portions, a hollow member receiving the scale therein, the hollow member being formed into essentially quadrate cross section, a head slidingly mounted on the scale for axial movement therealong for reading scale to generate a read scale indicative signal, a head slider associated with the head for axial movement with the head, the end portions, the receptacles and the head sliders being positioned on respectively associated one of first and second members with respect to the end portions, position of the head slider being determined with respect to a reference plane set on the outer peripheral plane on the hollow member in relation to the end portion.
