Abstract
Abstract An improved sensing head structure is provided that utilizes a flexible means for supporting a plurality of electronic components. A bracket is provided that supports the flexible support means in a preselected configuration and also provides a retaining clip portion that fastens a sensing head to the bracket. The bracket is attached to a frame portion of an electric meter in order to support the sensing head at a known position for sensing the passage of a non-reflective band on a rotatable disc under it. The use of two sensing heads permits the rotations of the rotatable disc to be counted and thus provides an apparatus for measuring electrical energy consumption. A spacer bar is also provided for the purposes of allowing the present invention to be utilized to more easily retrofit electric meters having rotatable discs of different sizes and positions within the meter.
