I am thinking through a thermocouple for the bean mass & wonder if anyone has any experience with bending one of these types?



I can also make up my own probe using stainless tubing & am contemplating:

1. Leave the thermoprobe "unbent", have a mount in the bean dump door. Insert the probe during roasting & pull it out when ready to dump beans.

2. Bend a thermoprobe like the one pictured & leave it permanently mounted above the dump door.

3. Make up my own probe, bend it & leave it permanently in place. If I go this route, do I need to ensure that the bare thermocouple wire does not touch the stainless steel tubing I'll be using for the probe? If so, any idea of material that I can use to center the thermocouple wire tip in the stainless tubing?

Any thoughts, ideas suggestions would be greatly appreciated.
Thanks,
Jon
