Hi there all,

       Here are two additional sets of info which may be of help:-

Chris,
       To add to your comments, I get the PSN e-mails but not a member and 
able to leave messages directly.  You might pass along any of those that you 
think will help.
       Yes, each of the metal cups that hold the sensor package are sealed 
with a copper evacuation tube, and a glass sealed connection.  Inside the 
stainless steel tube are 3 of the canisters, and each canister is about the 
size of a malted milk cup, like they used at the drug stores.  Each hangs 
from the leveling fixture, that is basically a ball in a containter that can 
be filled with air to let the ball float and seek level. You still have to 
level the entire instrument, since the range of this auto leveling device is 
only about at best 5 or 10 degrees.  (Sorry it's been years).  
       Yes, a multistage vacuum pump was used, and the canister was heated, 
to help evacuate the air, and then filled back to slightly above atmospheric 
pressure.  Remember each canister when leveled is not sensitive to north or 
south or up and down, it is a tri-axial package and each sensor covers part 
of the total 360 degrees of detection.  To get a up/down output requires the 
combining of all three instruments to provide a usable signal.  They work 
together to provide EW or NS and V outputs.  What I don't recal is if the 
output was derrived inside the electronics of the downhole package or 
external to it.  There are a set of electronic cards stacked on edge and 
vertical at the top of the internal frame that holds everything.  By removing 
the bottom plug or maybe it was the top, the case slides off to reveil the 
framework that holds all the electronics and the three sensors.  
       Inside each sensor canister is the capacitive detector, and 
electronics to provide an output which connects to the other internal 
amplifier electronics that connects via the downlhole cable.   The canisters 
can be opened, by heating the brass cups and pulling the cup from the top 
plate, all are made from brass (at least the early ones were) and soldered 
cup to top plate.  Each one is about 4 inch in diameter and about 6 inch 
long.  
       Deep hole versions had an alignment ring that was locked into the 
downhole pipe to provide alignment, later versions used in shallow holes had 
a North mark on the top.  I remember one early version having a hole lock pin 
that came out the side of the top of the casing, to lock it from moving in 
deep holes.  It was a motorized and geared pin that came out of the side at 
the top of the case.
       I did some of the original testing on the sensors when I worked at 
Teledyne Geotech, but was not involved in the manufacture of them, or any of 
the field installs.  Other than seeing them being built and going through 
tests in the area next to my environmental testing lab.  I operated the 
environmental test facility there during my 25 years at TG.  We had seismic 
level shake tables, a pressure test well to check downhole instruments for 
leaks,  and temperature chambers, and vibration test equipment.  
       If anyone needs information on older TG/Geotechnical equipment, I 
still have alot of equipment information that I had on my bookshelf.  When 
Teledyne started cutting back 9 years ago, I was working on a product for 
undergound leak detection, that I had a patent on, but the market wasn't 
ready for yet.  Works great, just Expensive...  I switched over to the 
meteorological product line (I did their systems engineering for them) which 
was also being sold off and ended up going to work for the competitor up here 
in Oregon.  He bought the product line and two people who were supporting it. 
 Me and a tech who remains in a office we set up in Dallas, doing field 
service work.
       If you have any questions, let me know, I'll try to answer them as 
best I can recall.

Hi Meredith
       Seeing lots of notes about the KS-36000, here is a brief sketch 
showing what they look like inside.  The one things that I think is important 
is that there is not a single canister that is used for NS or EW or V 
outputs.  It requires all three sensors to get these outputs.  In this way 
all the canisters could be identical in construction, only their orientation 
at 120 degrees apart provides the total output.  So each canister is mounted 
in the frame at 120 degrees from the other canister.   If a canister is bad, 
it could be replaced from one of the other packages, sort of mix and match to 
end up with working units.  Getting them "tuned" might be the only problem 
doing this, as I don't think each has an identical output.
       Again, it's been years, and I was mostly involved with the testing of 
the original prototype units, when I managed the environmental test lab.  But 
saw alot of them put together, and helped out a bit with the vacuum / heater 
chamber that was used to evacuate the canisters.
        They should transport pretty well, it's a pretty rugged instrument.  
Just avoid any sharp bangs, and keep them from hitting one another or rolling 
around.  If they still have the shipping containers for them, which is highly 
probable, use them.  It's a box about 1.5 ft square on the ends and about 6 
ft long, with lifting handles on the sides for 4 people to lift it.  They 
usually would keep the shipping case around since they were used to return 
them for repairs if that was ever necessary.

       I seem to remember that I can't add attachments to PSN mail. I have 
downloaded and viewed this image and can send it on as neccessary. There is a 
cable head, a motorised pump for levelling, cable termination and electronics 
boards, three identical suspended seis sensors and the base plug.
