ZWO EAF Measurements

[Simon Dunsmore]

Hi Folks,

Anyone out there who could tell me the measurements of the zwo eaf temperature sensor? I need to know the widest measurement at the sensor end.

Cheers

It's a very specific question and has piqued my curiosity: what are you planning to do?

The actual probe is 20mm long and 4mm in diameter. There's also some heat shrink sleeving around the cable which extends about halfway down the probe, this adds about 1mm to the diameter.

Hi and thanks for your reply.

I'm planning on running the probe through a length of alluminium pipe with the sensor part exposed and then mounting in atop the scope so that it extends out past the front of the rig. Just a neater solution than having it hanging downward.

Still waiting for it to arrive and so looking for a suitable bit of tube.

Thanks again for the reply.

Sounds like a good idea - I was wondering on using some hollow carbon fibre rod from a local radio control shop for the same thing.

Hi, Funnily enough, I was just looking at the same thing. I couldn't find aluminium tubing with a 5mm inner diameter. The sensor arrived today and its 4.5mm at the widest point.

This one should work?

That one would have been perfect. However, I just ordered a 8mm OD with 5mm ID alluminium tube. I'm thinking to mount it just under the guidescope on the dovetail bar using zip ties.

Interested in a pic of how it looks when you've done it Simon

OK, so the tube arrived today. Just about perfect for the sensor, just one wrap of tape and it's nice and tight. Tube is 30cm long. 

I have some sticky back plastic to wrap it in, then I'll zip tie it in place.

Tada!!!
