Hello all,
for medical research purposes we are desperately looking for a good
method to measure temperature very quickly.
The most important thing is the time constant of the measuring system;
it should be as low as possible.
Microbead thermistors appear to be one possible solution but they have
some problems, mostly mechanical ones.
We want to measure temperature in breath air, for example in
ventilated patients. So there are flow and water vapour that will be
dangerous for microbead sensors.
Encapsulated ones are not suitable since their time constant is too
high due to the encapsulation.
So there are two questions:
Is there an alternative to microbead thermistors for an ultrafast
temperature measurement?
How can microbeads be protected against mechanical and chemical
influences without prolonging the time constant by some encapsulation
or things like that?
Any hint would be greatly appreciated.
Thank you very much for your efforts in advance and best regards
Gerd
