[Halld-tracking-hw] Temperature sensor

[Yves Van Haarlem]

Hi,

I found some things on the omega site:

The air temperature sensor: 
http://www.omega.com/pptst/RTD-805_RTD-806.html

The controller:
http://www.omega.com/ppt/pptsc.asp?ref=CNI_SERIES

I like this but the controller has only one input channel (if you want 
rs232), so better use

a thermocouple:
http://www.omega.com/ppt/pptsc.asp?ref=IRCO_CHAL_P13R_P10R

With a six channel controller:
http://www.omega.com/guides/Results.html

What do you think?

Best regards,
 	Yves
