The device has been designed
for the non-contact measurement of the wall thickness profile of tube
sections. Measuring Principle A laser light line is projected onto the surface of the tube. The reflections on outer and inner surface of the tube are projected onto a CCD-line sensor. The distance between these two reflections is evaluated as wall thickness. The tube is clamped into a motor driven
chuck. During the rotation, the thickness of the tube circumference is
determined as function of the turning angle. Structure The device comprises the sensor head and the measuring electronics as well as the equipment for fixing and turning the tube. The device is part of the modular system
TC (tube control). In accordance with the customers requirements it will
be linked with further equipment, for example trend display, selection,
statistics, visualization and regulation. Specifications
