Hi Guys,

Just wondering if there was any adapters for machines without an exposed e61 groupheads.

I have a BFC Classica and there doesnt seem to be much room in there. I dont believe ill be able to fit Erics adaptor in there.



I was searching around and came across a few sites that sell thermocouples that fit into an M6. Anyone had any experiences with these or know of any alternatives?

Try sending a PM to Eric S. As the creator of the E61 thermometer, he might be able to help. He seems to know how to do just about anything.

The adaptor extends an additional 0.875" as compared to the head of the M6 x 8 allen head screw in the group. You would need an additional 0.375" to account for the bend radius of a thermocouple. This means you need 1.25" clearance between the head of the existing screw and the nearest obstruction.

Drawings of the adaptor are available on my crude FTP site below my sig.
Skål,

Well . . . short answer . . . yes.

But, there's always these guys: http://catalog.beswick.com/#HOME but you need the ability to tighten the initial fitting which looks difficult.

I have used that m6 screw thermocouple but not in that location. It would read the temperature of the group head metal whereas the E61 adapter measures the water temperature. The m6 thermocouple would be better than nothing.

You might be able to get a thermowell that is the same diameter as the price from the E61 adapter. You could cut it to length and skip in a very thin wire thermocouple. It might work.

Did some measurements last night. I only have a 2cm clearance. So Erics adapter wont fit.
I was wondering if a thermocouple could be placed at this location instead:


When i was cleaning out the grouphead on the weekend, i undid this bolt and there seemed to be 2 holes within the cavity that water flows through. I know this because i turned the pump on without the bolt in place and water squirted out of one of the holes.
