I'm finally doing my Digi-cool mod.

I'm feeling to lazy to dig out air, surface and immersion probes/instruments, I tested them last month. ;)


I don't find IR thermometers particularly useful for much besides looking for hot electrical connections and breakers/fuses, so I only have a really cheap one. :o
The thermal imaging camera is at the shop.
My next >$500 tool purchase will be a Fluke VT02 Visual IR thermometer, sometime this spring/summer. It will be perfect for electrical and motor diagnostics, as well as some limited duct leakage/building diagnostics on service calls.
Obviously it won't come near taking the place of a thermal imaging camera for building diagnostics, but it is something I can pack in my tool bag to every service call.

Infrared guns are good for little more than determining a temperature difference in my book. I use mine to walk around and shoot diffusers, around windows etc. The thermal camera I want is like 10 grand LOL...not exactly in my budget for a tool that would get used occasionally.

I've made sensors to fit my DC that aren't DC sensors and I've made side-by-side comparisons. No problems.

Appreciation. But did't [I] read an old post by you that went on to say ..."....The Cooper sensor mod have met varying degree of success and accuracy"?

I ask only to educate my self in this matter.

yTurbo,

I am asking if you are Hellenic because that is my heritage. I just think it would be gratifying to know I am not The one Hellenic only this forum.

I speak the language, but I a not seeking to become your "BFF">

I ttwold be a comforting thought another Greek was on board.

Thank you

I have read some of your post that suggested you are Hellenic Origin.
Thank you

I bet there are a lot of techs here with greek lineage including me.

Thank you.

Pleasure to make your acquaintance.

:o

Ok, then, a compatible 10k is a compatible 10k.....

I've used a couple of Emerson/CPC temperature sensors and they work quite well.

I just bought the sensor plugs from Digi-key and made up my own sensors.

I think that the "varying degrees of success" part of that has to do with the planning and execution of the mods rather than the sensors themselves.

Thank you JP.

The thermistors are set in a flexible sort of material so they do sink in a bit when attached to a pipe . Alot tougher than the Fluke style imo ( and I have some old Fluke K clamps , not putting them down at all ). They are quality stuff and they are not afraid to price them as such. Clamp force is strong on these as well. Like all clamps though , the ambient infiltration is there ( I cover them with white rags if it's windy ).

If I could change anything on these I'd add like a thin piece of soft gasket material for friction , but the same could be said for the Fluke K type as well.

I found that Tekmar Boiler Control sensors read exactly with Digicool sensors ( or the ones I have at least ) and have a concave section on them. I just need a bright idea moment to figure the best way to fit them in a clamp or something. Your Mod is cool Mark btw. - peace brothers

Mark - I just took a closer look , the thermistors in these clamps are actually thin sheet metal wrapped around foam. I thought that they were solid. No matter either way I guess , just stating.

Thanks for posting the pictures.
It looks like they are using the same sensor in those as they do in the pipe wrap probes, which is good.
The actual thermistor is on the back side of the metal that looks like it is wrapped around the foam like material. The metal protects the thermistor, and aids heat transfer to it.

I guess I'll go ahead and order a couple of them, and keep the pipe wrap probes as spares, and for when I'm working on larger equipment.
