Hey everyone, 

A suggestion for temperature monitoring - We've used in the past a standalone 
temperature monitoring box ( 
https://www.controlbyweb.com/x405/partnumbers.html )- you can put up to 16 
sensors on it and monitor them via a web page hosted by the box. I have one 
that will be needed when we start running - but it's not yet in use. I can 
bring it down for use with FST until then, or order a second unit if we want 
continued use. They're relatively inexpensive at ~$150. 

The temp sensors are just a TO-92 package with a molded boot - they can 
probably be taped down to the APV chips themselves with heat transfer 
mounting tape. (ex. 
https://www.controlbyweb.com/accessories/temperature_xdtsu.html )

Hi Flemming

Clips suggested by Gerard:

https://urldefense.com/v3/__https://www.mouser.com/ProductDetail/littelfuse/01220087z/?qs=w4dvuIu98YnZE2lfMuQ4ow*3D*3D&countrycode=US&currencycode=USD__;JSU!!P4SdNyxKAPE!UXBbhWMiYpqwLr34j3yGwDMPiRX-LpbpsBXd76u_Xn3lcFdtaINyhrnqTiTbVj0XE06Tkjs$
 

As pointed out also by Gerard, the temp sensors on the hybrids do not reflect 
the actual temperatures of the APVs.
Will you be able to get a thermal camera to measure the temperature of the 
APVs more directly?
