摘要： A nuclear gauge for making measurements of traveling webs in continuous sheet-making processes includes an enclosure, an encapsulated nuclear source, and a wheel-like member mounted in the enclosure means for carrying the encapsulated nuclear source between two angularly-displaced positions. The first of the angularly-displaced positions is the position where the encapsulated nuclear source makes measurements of a web that travels past the gauge and the second position is the location where the encapsulated nuclear source faces a sidewall of the enclosure means at a location remote from the first position. The nuclear gauge also has an aperture which is formed through the enclosure for providing a window through which the encapsuled nuclear source, when located in the first position, can emit radiation onto a web that travels past the window.

摘要： A nuclear gauge (7) for making measurements of traveling webs (11) in continuous sheet-making processes includes an enclosure (20), an encapsulated nuclear source (28), and a wheel-like member (10) mounted in the enclosure means for carrying the encapsulated nuclear source between two angularly-displaced positions. The first of the angularly-displaced positions is the position whereat the encapsulated nuclear source makes measurements of a web that travels past the gauge, and the second position is the location whereat the encapsulated nuclear source faces a sidewall of the enclosure means at a location remote from the first position. The nuclear gauge also has an aperture (16) which is formed through the enclosure for providing a window through which the encapsuled nuclear source, when located in the first position, can emit radiation onto a web that travels past the window.

摘要： The calibration of a laser caliber is described. The laser caliber uses first and second sensors to determine the distance to different sides of a sheet. A third sensor is used to determine the distance between the first and second sensors. The calibration of the first, second, and third sensors is done by positioning a test object onto the platform sensed by the third sensor. The platform is moved to multiple positions in order to calibrate the first, second and third sensors. Since the displacement of the platform moves the distance to the target of the first, second and third sensors the same amount, the sensors can be accurately calibrated for a number of different positions of the test object. A very accurate calibrating displacement measuring device such as an LVDT can be used.
