'[PIC:]Temperature sensors with high response time'

Is it possible to be measured quickly changing
temperatures like the temperature of the gases into
the combustion chamber of the diesel engine?
All I found in the net were the FISO Fiber Optic
Sensors that have good response time <1ms but the
temperature range is very restricted - only 200 C.
Does anyone know how can be measured so quickly
changing temperatures of about 1500 C?

I don't know what you mean by "quickly", but I believe a
thermocouple would be your best bet.
And look at Maxim's website for thermocouple interface
devices: they have one that combines the amplifier, a/d
and cold-junction compensation to give direct readout
in Celcius.

Well, you could look into EFPI (Extrinsic Fabry-Perot Interferometer)
fiber optic sensors, which can achieve microsecond response times
at 1400°C, but two-color IR measurement is probably more
available commercially and might stand up better in a combustion
chamber.

Maybe you should consider changing your settings rather than
inconveniencing all those other people who don't want EE or OT questions?
Just a thought.

A thermocouple isn't going to keep up with the rapidly changing temperatures
in a combustion engine.

There are three fundamental sets of considerations (1) the response and
repeatability of the transducer, (2) the acquisition/conversion and
processing time and (3) the resolution and accuracy requirement of the
measurement.  This should be a starting point assuming that you have
determined the range of measurement and error budget.
