Abstract

A monitoring sensor for metered amounts of powder includes a sensor sleeve to channel the metered amount of powder through it and a sensor base body, in which the sensor sleeve is held interchangeably. A holding plate is attached to the interchangeable sensor sleeve. The sensor base body has a contact surface for the holding plate. The monitoring sensor includes a holding magnet for pressing the holding plate against the contact surface.

First claim

What is claimed is:

1. A monitoring sensor for metered amounts of powder, the monitoring sensor comprising:
a sensor base body having a contact surface formed thereon;
a sensor unit including a sensor sleeve configured to pass the metered amounts of powder therethrough and a holding plate attached to said sensor sleeve and configured to removably seat on said contact surface so as to render said sensor unit interchangeable with another sensor unit; and,
a holding magnet arranged to magnetically act on said holding plate to press said holding plate against said contact surface and so hold said sensor unit in place on said sensor base body.

2. The monitoring sensor of claim 1 , wherein
said holding magnet is positioned in said sensor base body.

3. The monitoring sensor of claim 1 , wherein:
said sensor base body has a through opening formed therein; and,
said sensor sleeve, in a mounted state, is held free of play in said through opening.

4. The monitoring sensor of claim 1 , wherein, in a mounted state, an electrically conducting connection exists between said holding plate and said sensor base body.

5. The monitoring sensor of claim 1 further comprising a blast nozzle for said sensor sleeve.

6. The monitoring sensor of claim 5 , wherein:
said sensor sleeve defines a longitudinal axis; and,
said blast nozzle, when viewed in a cross section of said sensor sleeve, is oriented tangentially to said longitudinal axis of said sensor sleeve.

7. The monitoring sensor of claim 1 , wherein said holding plate includes magnetically attractable material; and, said holding magnet is disposed in said sensor base body.

8. The monitoring sensor of claim 7 , wherein said holding magnet is disposed in spaced relationship to said holding plate.

9. The monitoring sensor of claim 1 , wherein said sensor sleeve is made of plastic.

10. The monitoring sensor of claim 1 , wherein said holding magnet is attached to said holding plate; and, said sensor base body is formed, at least partially, of magnetically attractable material.

11. The monitoring sensor of claim 10 , wherein said sensor base body is formed of a magnetically attractable material in the region of said contact surface.

12. A monitoring sensor for metered amounts of powder, the monitoring sensor comprising:
a sensor base body having a contact surface formed thereon;
a sensor unit including a sensor sleeve configured to pass the metered amounts of powder therethrough and a holding plate attached to said sensor sleeve and configured to removably seat on said contact surface so as to render said sensor unit interchangeable with another sensor unit;
said holding plate including magnetically attractable material;
a holding magnet arranged relative to said holding plate to magnetically act on said holding plate to press said holding plate against said contact surface and so hold said sensor unit in place on said sensor base body; and,
said sensor sleeve being made of an electromagnetically permeable nonconductive material.

13. The monitoring sensor of claim 12 , wherein said sensor sleeve is made of plastic.

14. The monitoring sensor of claim 12 , wherein said holding magnet is disposed in said sensor base body.

15. A monitoring sensor for metered amounts of powder, the monitoring sensor comprising:
a sensor base body having a contact surface formed thereon;
a sensor unit including a sensor sleeve configured to pass the metered amounts of powder therethrough and a holding plate attached to said sensor sleeve and configured to removably seat on said contact surface so as to render said sensor unit interchangeable with another sensor unit;
said sensor base body including magnetically attractable material; and,
a holding magnet attached to said holding plate to magnetically act on said holding plate to press said holding plate against said contact surface and so hold said sensor unit in place on said sensor base body.

16. The monitoring sensor of claim 15 , wherein said sensor sleeve is made of plastic.

17. The monitoring sensor of claim 15 , wherein said sensor base body is formed of a magnetically attractable material in the region of said contact surface.
