Hi Billo and BoardBurner,
Thank you guys for your responses.
So here is what the system is about.
First you have to know what this is: http://en.wikipedia.org/wiki/Shape-memory_alloy
what I am doing is testing a piece of this material to find a very high cycle behavior like (100,000 cycles)
I am heating the wire electrically using 14 A in less than 100 ms from room temp to 100 degrees C.
right now we have position and force feedback which are used for control. I want to add temperature to the system not as feedback but just raw data to be analyzed later( hence NO processing).
the position and force are working and logging and analyzing fine. My problem is a temperature sensor (non contact).
To answer Billo question about why noncontact? I do not want to take out heat from the wire, no matter how small, because if I take out heat, then it will change the behavior of the wire.
I have consulted this page which has a list of all companies that manufacture IR temp sensors: http://www.directindustry.com/industrial-manufacturer/infrared-temperature-sensor-71767.html
I came across this which has the closest match to what I am looking for: http://www.micro-epsilon.com/temperature-sensors/thermoMETER_CT_basic/thermoMETER_CTfast/index.html
its the same company that Boardburner mentioned.
what I am exactly looking for are these specs:
- fast response (1 ms or less) (under 10ms is OK too)
- measurement of spot size of 0.5 mm
- measurement range of 0 to 200 degrees C
- 0 to 5V analog OR digital output to be read by microcontroller.
Also I think using photomultiplier and kinda making my own sensor would become too costly and not very accurate...
