INSTRUMENT MODULE SEP Drawing No. 101139 



As previously stated, the instrximent module is a pipe- 

 like housing coupling the various lengths of 3/4-inch- 

 diameter cable. In the present design, shovm on Figure 6^ 

 the body is closed at each end by plug-type bulkheads with 

 0-ring seals. The module shown has an end plug suitable 

 for mounting a pressure sensor. Cranmercially available, 

 bulk -head-type ff single-pin electrical connectors provide the 

 means for transmitting electrical signals c A coraraercially 

 marketed cable fitting is used to terminate the individual 

 load-carrying wires and transfer the loads to the cable- 

 fitting housing^, which may be rotated relative to the cable 

 fitting, permitting attachment to the instrument case without 

 rotation of the case relative to the cable o 



The cable fairing terminates at each module, which is^ 

 itself „ faired to reduce drag and vibration. 



The module at the bottom of the line also serves as the 

 depressor towstaf f (Figure 2) .
