hmmm
my equipment room is 85 to 95°F (the chillers are unhappy @ 95), so the vacuum box and contents would also be at 85-95 ? no ?
breaks are not so bad with 4-wire (load sense circuit) psus
with the present environmental chamber everything in and out is 4-wire (3 psus, 4 RTDs, except for 6 TC channels), and the chiller control uses the coolant inlet temp in LabVIEW to control a Kepco SN488-122, one channel of which controls the chiller
(wired, not yet operational)
a vacuum box - to me - is a huge amount of work to gain what ?
|absolute| knowledge of the heat input ?
but as long as I use the same die (insulation), my 'error' is constant
I deal with this right now in the testing of wbs and hsfs
wbs are on the heat die, hsfs are on an Intel ttv
the 'efficacy' of the heat die I can ascertain, with the ttv nothing (no means of measuring the actual dissipation, air flow and mean temp)
one part of the C/W 'mess'
