temperature sensors.

Hello,
I have a friend who would like me to develop a computer (using a BS2)
which will measure input, output and delta air temperatures on his
intercooler. (an intercooler is a device which is used on a turbo car
to cool the air after the turbo and before the intake)
The temperature sensor must be "industrial" in nature, and will be
mounted directly through the intercooler piping. Normally one would
drill a hole in the pipe, and weld in a bolt providing a mounting
point for the sensor.
My question is, does anyone know where I can find such sensors? They
need to be about 40 - 200 degrees Farenheight and easily interfaced
with the stamp.. :-)
If anyone can point me in the right direction where I would be able
to find such a sensor?
Thanks,
-James

Intercooler inlet temps can go WAY beyond 200F...(I know, I race a turbo
Grand National) You will need to use a K-type thermocouple probe. I did this
same test. You don't need to weld a "bung" onto the pipe, either...just
drill a tiny hole, insert the wire probe, and seal with JB Weld. Now...as
for interfacing the K type probe to the Stamp.....that's another story. I am
working on that...just don't have the time!!!! Till then I'd be glad to set
up your friend with a digital memory temp meter with probe for $99.
Good Luck-

Steve, Where can one find one of these K type thermocouple probes?

Industrial supply houses (like mcmaster.com) and lab suppliers (like
omega.com), but expect to pay industrial prices!
Go with the Chevy part, mucho cheaper at junkyard.
pm
but if you thonk your inlet temp is over 600 deg then a type K and its good
for up to 1700 deg F.
these are their useful ranges, they will go higher.
as to interfacing them to a system, analog devices makes the most wonderful
chip ive seen in a long time.
AD594 or AD595
the 594 is for type J
the 595 is for type K
both give 10 mv / deg F output up to within 2 volts of their vcc, so to get
0 to 5 volt output they need a 7 volt supply.
both also have cold junction compensation on the chips.
then feed this into an LTC1298 a to d converter.
you now have a digital signal to read into your processor of choice.
so with the type J thermocouple and the AD594 and the LTC1298 AND a 5 volt
vcc for the AD594 you would get 0 to 600 deg / F in 0.146484375 per deg
steps
my math could be wrong, but all the rest works real good.
been there.

converted to a Stamp friendly signal using an ADC or voltage-to-
frequency converter such as the AD654. Be sure to read the complete
data sheets and application notes for best results.

Note that the AD594/5 is pinned out so you can add an external gain
resistor, if you want more (or different) gain than the 10mV/C.
The data sheet explains this clearly.
