SBE 44 Underwater Inductive Modem
Configuration Details

For photos of standard shipment, click here.

Communicating with 1 or more 44s requires use of Sea-Bird Surface Inductive Modem (SIM), which provides serial interface (RS-232 or RS-485) between user’s computer & up to 100 IM instruments coupled to single cable. Purchase SIM & optional Inductive Cable Coupler (ICC) separately.

For Sea-Bird inductive modem instruments, see:

• SBE 39--IM for temperature and optional pressure recorder with inductive modem interface.
• SBE 37-IM and 37-IMP MicroCATs for CTD (conductivity, temperature, and optional pressure) with inductive modem interface.
• SBE 16plus-IM V2 SEACAT for CTD with inductive modem interface and auxiliary sensor input capability.

SBE 44 Mooring Clamp Wire Size Selections (Specify mooring clamp to match O.D. of wire jacket) -- MUST SELECT ONE

Cable fits loosely through IM coupling core / wire guide, & is clamped only at mounting clamp. See document 67142.

Thread for clamping to mooring cable:

• 44-1a (1/4 in. diameter): 1/4-28 UNF
• 44-1b (5/16 in. diameter): 5/16-24 UNF
• 44-1c (3/8 in. diameter): 3/8-24 UNF
• 44-1d (1/2 in. diameter): 9/16-12 UNC
• 44-1e (6 mm diameter): 1/4-20 UNF
• 44-1f (8 mm diameter): 5/16-24 UNF
• 44-1g (10 mm diameter): 7/16 -14 UNF
• 44-1h (12 mm diameter): 1/2-13 UNF
• 44-1i (16 mm, 5/8 in. diameter): 5/8-18 UNF

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 our standard (Impulse XSG/RMG) connectors. Like standard connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.
