Abstract
Method and apparatus for attaching a transducer to an object having characteristics to be measured. At least two attachment elements each including a number of pointed members are interconnected by a sensing element. Each attachment element includes a movable wedge member and at least one fixed wedge member whereby initial movement of the movable wedge member with respect to the fixed wedge member subjects said pointed members to a pressure force of a specified magnitude to press the pointed members into the surface of the object. Further movement of the movable wedge member with respect to the fixed wedge member generates a holding force on the pointed members less than the initial pressure force to hold each attachment element in engagement with the object regardless of transverse forces acting on the attachment elements.
