  • the sleeve 10 is preferably welded to the transition sleeve 60,
  • the second section 30 is mostly in the
  • Transition sleeve 60 arranged inside.
  • the transition sleeve 60 may have a collar portion in another embodiment of the invention.
  • the temperature sensor 70 is connected to the wires 95 by means of springs 90.
  • Fig. 3 is a cross section through a front end of
  • Temperature measuring device 80 shown. The front end of the
  • Temperature measuring device 80 is the sensor area of
  • Temperature measuring device 80 It can be seen that the sleeve 10 is partially disposed within the transition sleeve 60. Especially the second one
  • Section 30 is mostly located within the transition sleeve 60.
  • sleeve 10 welded to the transition sleeve 60, in particular laser welded, are. It can be seen in cross-section that the temperature sensor 70 is arranged in particular within the first section 20 of the sleeve 10. It will be appreciated that a cover of the temperature sensor 70 does not describe contacting the sleeve 10 with the temperature sensor 70. Rather, both the sleeve bottom 15 and the wall of the first section 20 of
  • Temperature sensor 70 arranged spaced.
