ABSTRACT:
Apparatus for conducting measurements of displacement, deflection, tilting, nd/or rotation of structures such as floodwalls, retaining walls, dam piers, buildings, embankments and the like is disclosed. The apparatus of this invention has the capability of simultaneously making measurements in two planes, parallel and perpendicular, with respect to an axis or other predetermined reference. Further, the apparatus of this invention includes means for determining the azimuthal bearing of the apparatus relative to the axis or other predetermined reference when the aforementioned measurements are conducted. The apparatus of this invention includes a measuring unit having a housing that houses first and second servo-accelerometers; first, second and third amplifiers; and a rotational variable differential transformer. The amplifiers are electrically coupled to a meter by means of a cable having electrical conductors. Measurements can be obtained with the measuring unit in a fixed mount orientation or in an orientation where the measuring unit is moved vertically through a tube or casing. In the fixed mount mode of operation, a base plate is secured to the bottom of the measuring unit housing and the base plate is then secured to an embedded anchor or base plate. When the measuring unit is moved vertically through a tube or casing to obtain the desired measurements, a first set of guide wheels is secured to the top of the measuring unit housing and a second set of wheels is secured to the bottom of the housing. The interior of the tube or casing through which the measuring unit is moved vertically contains grooves or channels that serve as guide tracks for the two sets of wheels.
