Inductive Cable Coupler (ICC)

Inductive Cable Coupler (ICC)

Link between underwater IM instruments and the SIM / IMM, used in applications where the plastic-jacketed wire termination is grounded to seawater.

The ICC is a link in Sea-Bird’s Inductive Modem (IM) telemetry systems, used in applications where the plastic-jacketed wire termination is grounded to seawater (at a chain, for example). The ICC clamps to the jacketed mooring wire, and makes electrical connection with the Inductive Modem Module (IMM) or Surface Inductive Modem (SIM) via a cable housed in reinforced-rubber conduit. The conduit’s upper end is fixed to the buoy hull with the provided clamps. The conduit/cable must be long enough to prevent buoy motion from pulling it completely straight and putting tension on the ICC.

Inductive Modem System
Note: ICC includes pigtail cable, conduit, and buoy hull clamp; molded-on cable connector and bulkhead connector optional.

Each IM system typically includes:

  • IMM or SIM, housed in a buoy or on land. The IMM or SIM provides the link between the underwater IM instruments and the computer / buoy controller.
  • Inductive Cable Coupler (ICC), which links the underwater IM to the IMM or SIM for typical buoy applications.
  • Underwater IM instruments, up to 100 inductively coupled instruments on a jacketed mooring wire. Compatible instruments include:
  • SBE 37 MicroCAT C-T (optional pressure) Recorder — 37-IM, 37-IMP (integral Pump), or 37-IMP-ODO (integral Pump and integrated Optical Dissolved Oxygen).
  • SBE 39-IM Temperature (optional pressure) Recorder.
  • SBE 16plus-IM or 16plus-IM V2 SeaCAT C-T (optional pressure) Recorder, which can acquire additional data from optional auxiliary sensors (oxygen, fluorescence, etc.).
  • Underwater Inductive Modem Module (UIMM) or SBE 44 Underwater IM, which links to a current meter, Doppler profiler, etc. with a standard serial interface.
  • Instruments by other manufacturers with built-in Sea-Bird underwater inductive modems.

FEATURES

  • Sea-Bird's field-proven IM telemetry, with more than 3000 Sea-Bird IM instruments deployed since 1997.
  • Five-year limited warranty.

COMPONENTS

An IM system provides reliable, low-cost, real-time data transmission for up to 100 IM-enabled instruments using plastic-coated wire rope (typically 3x19 galvanized steel) as both transmission line and mooring tension member. IM instruments clamp anywhere along the mooring, which is easily reconfigured by sliding and re-clamping instruments on the cable. In a typical mooring, an Inductive Modem Module (IMM) in the buoy communicates with IM instruments and interfaces to a computer/data logger (not supplied by Sea-Bird) via RS-232. The data logger is programmed to poll each IM instrument for data, and sends the data to a satellite link, cell phone, etc.

PRINCIPLES OF INDUCTIVE COUPLING

A transformer has two or more coils that share a magnetic field. Materials such as ferrite can be used to form a transformer core that ensures the necessary sharing of magnetic fields. When using the ICC with Sea-Bird’s IM system, the ends of the mooring cable are grounded to the seawater. This causes a current to flow through the mooring wire and seawater. The ICC senses this current, providing a voltage for presentation to the IMM or SIM.

Inductive Cable Coupler

Communicating with 1 or more IM instruments requires use of Surface Inductive Modem (SIM) or Inductive Modem Module (IMM), which provides standard serial interface (RS-232) between user’s computer & up to 100 IM-compatible sensors coupled to single cable. An Inductive Cable Coupler (ICC) is always required if specifying SIM-COUPLED, & is often required if specifying an IMM.

ICC Version 4a is a 20-turn coupler, while Version 4b is a 100-turn coupler. Other couplers are available for OEM applications (contact Sea-Bird for ordering information). Table below summarizes power requirements for each:

  20-turn ICC

SIM 35 mA 20 mA Not allowed

Clamp Size Note: Mooring wire is typically specified by wire size, not by outer diameter (O.D.) of the mooring wire jacket. Verify the wire jacket O.D. before selecting the clamp size. The clamp size must be less than or equal to the wire jacket O.D. but larger than the wire diameter. For example, Mooring System Inc.’s specifications for 3x19 wire rope (in 2016) are as follows:

Wire Diameter Jacket Diameter Recommended Sea-Bird Clamp
3/16 inch (5.0 mm) 0.255 inch (6.5 mm) 1/4 inch
1/4 inch (6.5 mm) 0.330 inch (8.4 mm) 5/16 inch
5/16 inch (8.0 mm) 0.392 inch (9.9 mm) 3/8 inch
3/8 inch (9.5 mm) 0.453 inch (11.5 mm) 10 mm (0.394 inch)
