Exactly. We need a continuously record the temperature. Therefore, the two
proposed options, the pencil and the thermocouple are not suitable for our
purpose. We will use several thermocouples within the cone, temperature
recording. But abroad, will be in direct contact with the flame. That is why,
we want to use an infrared thermometer. Does anyone know how we can do one and
connect it to the computer?

Thermocouples are cheap and work well,
but if they are embedded in a sample that gets torched, they will
at best record the surface temperature of the sample at the brief
moment they are at the surface. It may work - and even provide
usefull data - but an IR thermometer will read the surface
temperature continuously.

A type K thermocouple is good to 1250 C. It will need a
simple instrumentation amplifier to get the signal voltage
to a range compatible with the Arduino A/D converter. For
about $10 in parts you can build your own IN-AMP. There are
several choices for single chip IN-AMPs that will do the job
and here is a board from China for $10, and the chip output
is 10mv/deg C.

Thanks
for your reply Markus,
It
is a good idea. The main problem I see
is that we need to measure high
temperatures. I do not know exactly how
much, but around 1200ºC. And this only
measures halfway. Do you know if there
is a sensor for arduino with this
possibility?

Hi Vicente,
It is quite easy to build a data
logger with an Arduino based micro
controller, SD card, SD card socket,
HEF 4050 voltage level shifter,
DS1307 RTC and one (or more)
MLX90614 IR thermometer(s) which
communicate(s) over the I2C bus as
well.
I am just doing this for a medical
project.

Hi all again,
Although a long
time do not talk about it, yet
we continue the investigation
of ablative materials.
For the study of
the material that will coat
the nosecone of our rocket;
Richard, Mattias and I already
started last summer to work on
it.
Throughout this
week, I've been talking to
Hans, and he thought the
possibility to also measure
the temperature on the side of
the wall that is in contact
with the flame. Would be
measured by an infrared
thermometer.
I am contacting
you to see if anyone is
interested, or know how, to
attach an infrared thermometer
with data logger that Liam is
manufacturing for
thermocouples.
By this, we can
obtain pairs of temperatures
at the same point. Both
outside and inside of the
wall, in order to obtain among
other data, values of thermal
conductivity and heat capacity
of each material.
Thanks in advance
for your cooperation and
interest.
