What if I told you the most sensitive thermocouples, heat flux sensors, and radiometers...

For space flight used by SpaceX, Nasa, and pretty much everyone not communist were made by a very small business in a shop by about 6 people that looks ALOT like this.

I believe you

A thermocouple is nothing but two wires twisted together. Doesnt take a lot of technology.

You just gonna leave us hanging?

Without looking it up, what are the principles of a thermocouple

I wouldn't be surprised actually. The problem with some very low volume high quality things like that are that at some point the people die off and the knowledge is lost.

Two different metals come in contact and emit a very small voltage. The voltage will change based on temp. If you can read the voltage, you know the temp.

Thermocouple is a electric sensor to measure temperature.
Think electric thermometer, meat probe, etc.

Two dissimilar metals produce a certain voltage at a certain temperature.
RTD is similar to a thermocouple, but instead of producing a voltage, resistance changes

Yes, this company just got bought because the guy that owns it who has his PHD is getting ready to retire. The guy that invented all the technology has passed away and alot of the workers have been doing it for years.
Some of it envolves wrapping wires the size of spiderwebs perfectly around other super small wires, etc under a microscope. Along with all sorts of other crazy stuff.

It's two wires of different metals soldered together.
No, not alot to make one. To make one's that are super sensitive, have a super fast reaction time, and can handle very extreme temps it takes something special.

Temperature always has a slow reaction time.

Well, are you?

Yes, to me it wasn't crazy that it was made by a small business by just a few people... but that the shop had 1960s and 70s electrical equipment being used to test them, looks like a super cluttered mad scientist dark dungeon, etc.
shite crammed in every nook and corner. Test results printed by a ink plotter, etc.
Just not the clean bright organized workshop you would imagine.

Nuclear batteries use thermocouples to generate power. Curiosity, the Mars rover, has a nuclear battery. The greater the difference between the heat at one end and cold at the other the more power they produce.

Why are people downvoting the fact that temperature has a slow reaction?

It's like a throuple...but hotter.
