Nozzle for processing workpiece e.g. by laser beam - consists of nozzle body with sensor element of e.g. copper@ attached to insulating body for contactless measurement

摘要

Nozzle consists of a nozzle body (2) with a sensor element (4) at the tip for contactless measurement. The sensor, e.g. of Cu, is attached to an insulating body (3). A coaxial socket (5) is located at the sidewall, with a signal line connection (6) and a further line connection (7). The sensor is in contact with a second line (11) which is linked to the connection (7) via a resistor (14). ADVANTAGE - Correct connection of the sensor can be monitored.
