why dont you just buy it. its only $40

what im asking is in the title "How do i make a thermalcouple give me a 0-5v signal?"

man what happend the the hmt do it yourself way? if i have to ill buy it. i just want to know how it works.

racepak

me too

this will be a nice addition to my rpm converter

HMT is about saving money, but when something is that cheap i dont see it as worth the effort

I know how to do a 0 to 5 V power supply but is that what you needed?

Rene, it has an amplifier in it that is scaled to provide a 0-5 volt output.

Thermocouples produce small amounts of voltage depending based on the temperature difference of the two junctions. Forewarned, it is not completely accurate.


If you want, I'll build you one when I have some spare time.

$40 is a lot more than $10 in parts.

Not even close. Myabe a few bucks.


Or, if you are like me I have all the parts already.
