Abstract
The present disclosure relates to an ultrasound measuring device for measuring extruded products in an extrusion line, the ultrasound measuring device comprising multiple sensors, each emitting ultrasound waves and detecting reflected ultrasound waves, the sensors being distributed around an axis and aligned towards the axis, a controller device for activating the sensors and receiving measuring signals from the sensors.
Claims16
An ultrasound measuring device for measuring extruded products in an extrusion line, the ultrasound measuring device comprising
- multiple sensors, each emitting ultrasound waves and detecting reflected ultrasound waves, the sensors being distributed around an axis and aligned towards the axis,
- a controller device for activating the sensors and receiving measuring signals from the sensors,
- wherein the multiple sensors are arranged, in relation to one another,
- helical or spiral around the axis, and/or
- sequentially offset in relation to one another both in the circumferential direction around the axis and in the direction of the axis,
- the controller device activating the sensors in such a way that always one sensor transmits and detects and the other sensors detect passively.
A method for measuring an extruded product, where the extruded product is transported during the extrusion process along an axis and continuously measured by at least one ultrasound measuring device including multiple sensors, the multiple sensors being
- arranged successively in both the circumferential direction around the axis and offset in relation to one another in the direction of the axis, and/or
- arranged helically or spirally around the axis,
- wherein an active-passive measurement always one of the sensors transmits and receives and the other sensors detect passively.
