Laser scanning systems and methods are disclosed herein that can provide quick and efficient measurement of extruded ceramic logs, particularly related to log shape, during manufacture. Two two-dimensional laser scans from respective laser scanners are performed and the resulting laser scan data is combined to form a three-dimensional surface shape measurement of the ceramic log. The systems and methods disclosed herein enable a non-contact measurement of the extruded ceramic log, which reduces the risk of physically damaging the log. The measurement results can be used to adjust the extrusion process of the extruder that forms the extruded ceramic logs.

Laser scanning systems and methods for measuring extruded ceramic logs

In-line systems for and methods of measuring the moisture content of ceramic material within an extrusion system used to form ceramic articles are disclosed. One method includes arranging, relative to the extrusion system, at least one radio-frequency (RF) sensor system having an RF antenna, and generating through the RF antenna an RF field that resides substantially entirely within the ceramic material. The method also includes, in response to the RF field interacting with the ceramic material, generating in the RF sensor system a signal representative of a raw moisture-content measurement of the ceramic material. The method also includes generating calibration data by performing RF moisture-content measurements on samples of the ceramic material having different known moisture contents, and establishing a calibrated moisture-content measurement using the raw moisture-content signal and the calibration data. Both contact and non-contact systems and measurement methods are described.
