ABSTRACT:
An apparatus for measuring the angular position of a first element, rotatable with respect to a second element, includes an arcuate scale mounted to the first element. An arcuate housing substantially encloses the scale, and defines an arcuate slit which extends along the housing. A pair of sealing elements, one disposed on each side of the slit, are provided to seal the slit, and a scanning unit is disposed within the housing, adjacent the scale. This scanning unit is coupled to the second element by a coupling member, which extends through the slit between the sealing elements, such that the scanning unit moves along the scale when the first element rotates with respect to the second element. This apparatus is particularly suited for rotary or swinging tables having a range of angular movement less than 360.degree..
