good idea with the shelf regarding accessability. Is that s939 case an AMS gtower? Those are nice

does that mean your going to test GPU blocks soon?

MH I have about 4 things going on at various stages of completion. The easiest for me to do is to try and generate some numbers for the modeling that Cathar and Les and Lolito_Fr were doing a while back. It's easiest because it uses all the old equipment and is separate from this new setup. The other easy thing to do is to begin collecting dP measurements on GPU and CPU blocks.

The other two things I'm doing are a little harder because they involve some rather drastic hardware mods. I have to pull the LM63 IC off this 9600XT and tap into the diode from that way and then calibrate it for GPU block testing. I also have to cut open my socket 939 socket and solder diode wires onto that 3000+. I've been sorta putting both those things off because I'm a big sissy.

Yes that's an AMS Gtower case. Bruce has shipped me a full tower with dual 120mm holes cut in the top for complete system testing. I'm waiting on it to get here to start messing with that project (instead of retesting a bunch of blocks for socket 939 I'm going to try and get a nice complete system testing setup running).

sounds like not enough hours in a day...
only reason i'm asking about teh GPU test is cause I have a video card that wants to be watercooled again...
the crystal orb is so loud in comparison now...hehehe

ok this is probably one of the best threads I could update, right? Talcum kindly donated a DVM card for y 3497A and also wired it up as a six channel DVM with labview vis and everything! 2 channels convert current to voltage (handy for 4-20 mA output instruments). I got it mostly working last night; I still have an issue scanning those channels while monitoring mA reading from the dP xmitter with a separate DMM. Labview makes no sense to pH.

Tonight I'll cut a hole in the mobo tray of the GTower Server, clean up my testing room and install test system in that GTower case. Friday I plan to collect the first full set of data with the Labview setup just to verify it works as intended. Then I'll probably spend a week running baseline tests on all the instruments (no fun but crucial).

After getting my bench up and running I have come up with about 10 years worth of projects to test with it. :D Wish I spent the time and money on it 4 years ago.... I already have a bunch of stuff done. Just waiting on you guys to get things re-organized to post it. Headed to Florida monday untill the 1st so I am not in a hurry anyway. Man, got to order a lot of copper when I get back....

(I use a HydrX soln to fill and bleed the lines, with isolation and bleed valves at the DUT)

I just had another battle with algae, that I lost, again
multiple big tanks of warm water, pumps, hoses, valves - all to be cleaned (ASME pump test setup)
"Algae Destroyer Liquid" (0.6% Simazine) @ 1 tsp/10gal is crap, precipitates and dosen't work
going to treat as a swimming pool, clorox

Regarding the technology developed, it consists of a system based on low-intensity, high-frequency ultrasounds which, together with the introduction of micro-bubbles of air, produce an effect of photo-sonoluminiscence. The concentration of ultrasounds by constructive interference generates a pressure front that produces a decompression of the gases dissolved in the water. This wave front produces a luminous plasma around the bubbles, as well as high pressure and temperatures.

These pressures and temperatures have two effects: on the one hand, they eliminate the circulating bacteria and, on the other, they generate an oxidative stress that is transmitted throughout the water refrigeration system. This stress, together with the continuous loss of circulating bacteria throughout the system, reduces the formation of biofilm even at extremely low levels – and maintains this to such an extent that the fixing of “legionella” bacteria or any other micro-organisms needing biofilm in order to grow in the system, is impeded.

how a "ghetto" DIY version may be possible I dont know

not to derail the thread or anything ;)

Interesting links, Ice Czar. Do you have an opinion on UV sterilization?

well I dont have a qualitative opinion
Im familiar with UV irradiation though

but I did find that as a "new" development interesting especially in relation to this
http://web.mit.edu/hmtl/www/papers/DHIR.pdf

well that and a paper I read a summary of a few years back about sonic induced microbubbles in enhancing heat transfer

back on topic
looking at various Rosemount 1151 Pressure Transmitters
I see all sort of "Smart Ranges" 5, 8, 9
what does that denote?
a calibration range?

Got it.

Goto: http://www.rosemount.com/document/pds/1151.pdf and scroll down to page 16 for a list of the range codes.

There's a reference to "smart ranges" on page 3.

edit: see http://www.rosemount.com/products/pressure/m1151.html for more info.

aha
thankyou very much !!! ;)
