Abstract:
1. A method for obtaining a measurement in an in-line system for detecting presence of an out-of-parameter part, the method comprising: conveying a tubular member having an inner diameter and an outer diameter that define a wall thickness, the tubular member conveyed in a conveying direction to a detection system comprising a laser sensor arranged and configured to direct a beam of light onto an upper end surface of the tubular member for obtaining a measurement, the laser sensor being offset vertically from the upper end surface of the tubular member and offset horizontally in a cross-conveying direction from a center of the tubular member such that the beam of light is directed onto an outer side of the upper end surface between the inner diameter and the outer diameter of the tubular member; and directing the beam of light onto the upper end surface at the outer side of the tubular member as to measure a height of the tubular member, the beam of light projecting along a continuous path of the upper end surface from a front quadrant of the upper end surface to a rearward quadrant of the upper end surface, the continuous path having a length that is greater than the wall thickness of the tubular member.
