Is Temperature the Future of Digital Vaping?

[happydave]

got the thermocouple inside the drip tip
duck tape for a good air tight seal.
going to calibrate the thermocouple, shoot some video and post it here soon.

Don't know what I'm looking at.
Looks like a knife.

And a white round thing that.... is that the top of a drip tip?
And like there's a little eyeball looking up at me from the drip tip?

And what's that wire doing there? Somehow that wire is supposed to connect the a thermocouple somewhere ?

uhh yeah that twisted wire IS the thermocouple.

Ah.. good good; so you're measureing the temperature in the coil area then I take it;

what's your measureing device; reads directly in degrees or are you reading voltage then calculating ?

mV then using this chart to convert to temp
this is a "k-type" thermocouple

If your device is measured in voltage, then when you want "more", you turn it up, and when you want "less", you turn it down.

If your device is measured in watts, then when you want "more", you turn it up, and when you want "less", you turn it down.

If your device is measured in temperature, then when you want "more", you turn it up, and when you want "less", you turn it down.

No matter how it's marked, or the terminology used, the same things happens. Wattage or temp may be listed, but it's still going to raise the voltage when you turn it up and lower the voltage when you turn it down.

TOTALLY AGREED........ it's what you are used to... no real diff

millivolts! oh; yeah; just checked; my cheap multimeter actually does have a 200mV scale; never had a device that needed that

Setting the thing is just one half; keeping it there is the other.

Set the voltage 3.7 volts; done

Set the wattage to 10 watts: if your ohms changes, the voltage adjusts so that the wattage is maintained. Some mods do it on the fly; I assume some cheaper mods only check the ohms when you first press the button.

Set the temperature: if its getting hotter the mod has to drop voltage / vice versa.

I assume you know that you need to measure the temperature of the cold junction and then add the voltage represented by that to the voltage that you are measuring?

Next week -- how to suck eggs.

ok so here is test 1
temp was around 20°C
chart link http://www.pyromation.com/downloads/data/emfk_c.pdf


next test will be a tank and VV device

0.7 mV.

So looks like about 10 degree celcius.

 

[happydave]

0.7 mV.

So looks like about 10 degree celcius.

10°C would be .397 mV

in my test it hung out around .7 mV with a peak of .9 mV
or around 20°C

Thanks. Were you using an ordinary ego there? Ego are regulated at 3.3 volts. So with 1.8 ohm coil that would be 6.05 watts. And you got around 20C.

It gets interestinger.

I guess that rules out the drip tip as a place to get meaningful measurements.

1000 mah pass-through, unregulated

Unregulated egos output 3.3 volts. So basically - at 6 watts temp is around 20C, well under core body temp.

an unregulated ego puts out 4.2 at first and do to voltage drop under load it hovers around 3.7-3.9 volts

regulated ego batteries can put out 3.3 or 3.7 volts with no drop under load... depending on what ego battery you buy it will be 3.3 or 3.7
