ABSTRACT:
The adjustable measuring parallel has a head assembly that includes upper and lower slider blocks that are mated to each other at an incline, which may be a common transversal incline. The upper slider block is connected to a movable extender rod member which has connected to its other end a ferromagnetic core. The lower slider block is connected to a stationary extender member which is threaded to a handle that has a cavity in which a linear variable differential transformer (LVDT) is fitted. By moving the movable extender member in directions along the longitudinal axis of the instrument, the upper slider block is forced against the lower slider block such that relative movements are effected between the two slider blocks along a direction orthogonal to the parallel surfaces of the slider blocks, or the longitudinal axis of the tool. As the movable extender member moves longitudinally, the ferromagnetic core connected to its end likewise traverses through the aperture of the LVDT, thereby generating an induced EMF which is converted by the LVDT to a DC voltage that is indicative of the distance of the relative movement between the parallel surfaces of the slider blocks. Instead of using electronics to convert the relative orthogonal movements of the slider blocks to a reading, mechanical indicators such as a dial indicator may also be used.
