摘要:
The invention provides a nozzle (2) for abrasive waterjet cutting. The nozzle (2) comprises: a body (4) comprising an outer surface (6); a passage (8) through the body, said passage comprising: in inlet section, an outlet section and a passage direction (14), said passage being configured for guiding an abrasive waterjet. A resistive strain gauge sensor (20) comprises a sensitivity direction (22) along the passage direction. The outer surface is circular and presents a planar area (40) for the sensor which is connected by a Wheatstone bridge. The invention also provides an abrasive waterjet nozzle manufacturing method. The invention also provides a use of a strain gauge sensor attached to a nozzle for abrasive waterjet cutting, for measuring bending vibrations.
