SBE 36 and PDIM

SBE 36 CTD Deck Unit & PDIM (Power Data Interface Module)

Surface power and real-time data acquisition for Sea-Bird CTDs; two-way communication over single- or multi-conductor sea cable and ample power for auxiliary sensors.

The rack-mountable SBE 36 interfaces with an underwater Power and Data Interface Module (PDIM) to provide surface power and real-time data acquisition for an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD, or SBE 50 Pressure Sensor. The SBE 36 remains at the surface, while the PDIM is installed on or near the CTD (CTD refers to the listed CTDs as well as the SBE 50 Pressure Sensor). The system allows for two-way communication for the CTD over a single- or multi-conductor sea cable, and provides ample power for auxiliary sensors that may not otherwise be supportable by a battery-powered CTD.

FEATURES


Note when using SBE 50: Seasave does not support this system; real-time data can be viewed in Seaterm (terminal program). NMEA and/or Surface PAR data (if applicable) is output as raw data.

SBE 36 PDIM Connector (for test cable) Selections — MUST SELECT ONE
36.x1 For PDIM with XSG/AG connectors

Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

PART # DESCRIPTION NOTES
PDIM

Underwater Power/Data Interface Module - accessory for SBE 19/19plus/19plusV2/25/25plus CTDs. Converts surface power for use by CTD and provides two-way communication interface between CTD and Deck Unit via single-conductor armored cables up to 10,000 meters long. Includes Seasoft software and complete documentation. Requires use of SBE 33 or SBE 36 Deck Unit - ordered separately. Does not include interface cables or mounting hardware – ordered separately.

PDIM is required to interface SBE 36 Deck Unit with CTD. PDIM housing is anodized aluminum, & is rated to 6800 m. PDIM order includes sea cable extension cable & pigtail cable, dummy plugs, & jackscrew kit. To order PDIM mount kit & CTD interface cable, see SBE 36 Accessories & Spares above.

Note: PDIM can also be used with SBE 33 Carousel Deck Unit (when used without an SBE 32 Carousel Water Sampler), to provide same functionality as when used with SBE 36 Deck Unit.

 

PDIM Connectors Selections — MUST SELECT ONE
PDIM.11 XSG connectors PDIM connector type (XSG or wet-pluggable MCBH) must match CTD connector type. Wet-pluggable connectors provide easy connectability in damp (e.g., rolling, slippery deck) or cold environments (XSG connectors may not seal well in extreme cold; we recommend connecting cables in warm ship’s lab rather than on deck for these conditions). Wet-pluggable connectors are not meant for literally plugging cables in submerged underwater; both our XSG connectors & wet-pluggable connectors must be mated in air.
PDIM.12 Wet-pluggable MCBH connectors
