INSTRUMENT ASSEMBLY AND MAINTENANCE 



A. Initial Assembly 



1. The transducer stack is created by placing the transducers 

 within the plexiglass wafers and attaching the acrylic stand-off 

 rods between the wafers. 



2. The stack is attached to the bottom of the water-tight 

 cylinder (can) end-cap. 



3. Nylon tubing is connected between the the bottom of the 

 end-cap and the transducer pressure ports. 



4. The wiring is then completed terminating to a 16-pin connector 

 positioned just below the can end-cap. 



5. The exterior stainless steel tubing and acrylic diaphragm 

 housings are attached to the top of the end-cap. 



6. The center housings are larger in diameter and should connect 

 to the slightly "elevated" Swage-Locks on the transducers.
