Optional High Pressure Penetrators
Sediment Traps deployed at depths from 7,000 m to 10,000 m, require high pressure penetrators
on the controller COM port and motor connector. These penetrators have a locking collar with an
inner locking ring. Sediment Traps with the deep option do not have a pressure relief valve installed.
Appendix E ‘Deep Sediment Trap Connectors’ provides more details.

Gear Plate Assembly
The gear plate assembly attaches to the top fixed plate with seven (7) bolts. On the gear plate
assembly, four (4) bolts with plastic washers attach the gear ring to the bottom fixed plate. An
unthreaded alignment hole, referred to as Port ‘Zero’ (0) aligns the rotator assembly when the Trap
is deployed to protect the integrity of the adjacent sealed bottles and prevent sample contamination.
The first sample bottle hole is labeled ‘1’.
