SBE 32 Carousel Water Sampler - An innovative design, free of the reliability problems associated with motor-driven types. The Carousel has no moving-shaft seals that can bind up at low temperatures or under pressure because each bottle position has its own magnetically-activated lanyard release latch. Only the magnetic field -- not a moving part -- links the Carousel's lanyard release mechanism with the pylon control electronics.
Sea-Bird's Carousel has been extensively deployed throughout the world's oceans, where it has built a reputation for reliability and ease of use. The Carousel has rapidly become the standard for oceanographic water sampling.
SYSTEM ENGINEERED - PERFORMANCE PROVEN - TIME TESTED
The heart of every Carousel is the magnetically-actuated lanyard release (shown at right). A pressure-proof electromagnet at each bottle position is energized on command to release the latch holding the bottle lanyard. Titanium, acetal plastic, and other corrosion-resistant materials are used in the latch and magnet assembly. The latch array's modular construction makes servicing easy.
SBE 32 (FULL SIZE) CAROUSEL
The Carouselís electronics/release assembly and mounting hub are standard components of all 12- and 24-position systems, and are available separately. When the electronics/release assembly is bolted into the mounting hub, a drop-in replacement is created for the pylon assembly commonly found in many existing water samplers, allowing reuse of existing bottle mount stands and adapter plates when upgrading to the more reliable and convenient Carousel design.
36-position Carousels typically require a custom design suited to the intended bottle size, and are built to meet specific application requirements for size, weight, and materials. One example of a 36-position electronics/release assembly is shown at left, installed in a custom 36-position stainless steel frame for 12-liter bottles.
SBE 32C COMPACT CAROUSEL
For use with limited vertical clearance, the SBE 32C is a 12-position sampler without CTD extension stand. It supports bottles up to 8 liters, and accommodates a 9plus CTD mounted horizontally inside the bottle circle. Bottle positions are closely spaced into 2 arcs, leaving spaces between the arc ends to provide unobstructed flow to the 9plus or to allow mounting an SBE 19, 19plus, 19plus V2, 25, or 25plus CTD (or SBE 49 CTD for real-time operation only) and/or other instruments vertically, using an accessory mounting fixture.
SBE 32SC SUB-COMPACT CAROUSEL
The 12-position SBE 32SC is sized for 1.7 or 2.5 liter bottles. When used with an SBE 19, 19plus, 19plus V2, 25, or 25plus CTD (or SBE 49 for real-time operation only), it offers a small yet full-featured system, well-suited to operation from small boats.
The Carousel can be controlled in several ways:
Each of these is described briefly below; see the applicable (hyperlinked) specification sheet for more details.
SBE 11plus Deck Unit
The Carousel is designed to be connected to the SBE 9plus CTD and SBE 11plus Deck Unit, and controlled via the SBE 911plus modem channel.
SBE 33 Carousel Deck Unit
For stand-alone Carousel use (without a CTD), the SBE 33 provides power and real-time control to the water sampler. When used with an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD, it also provides a real-time data telemetry link and power for the CTD and auxiliary instruments. The SBE 33 includes a NMEA 0183 interface to allow GPS position data to be appended to Sea-Bird CTD data, and an optional auxiliary A/D channel to interface a surface PAR sensor.
Auto Fire Module (AFM)
The AFM allows Carousel operation without a conducting seacable by firing bottles:
The AFM also records bottle number, firing confirmation, and 5 scans of CTD data for each bottle fired. At the end of a cast, data from the CTD and from the AFM are both uploaded using the provided software. Setup and checkout are also performed (without opening the housing) through the software. Power is supplied to the Carousel by the AFM's internal batteries.
SBE 17plus V2 Searam Recorder & Auto Fire Module
The Searam allows Carousel operation with an SBE 9plus CTD without a conducting seacable. Power is supplied to both CTD and Carousel by the Searam's internal battery. Using pressure data received from the SBE 9plus CTD and a programmable table of bottle closure pressures, the Searam commands the Carousel to close bottles on the upcast. Setup, checkout, and data uploading are performed (without opening the housing) through the provided software.
Seasoft© V2, our complete Windows 2000/XP software package, is included at no extra charge. Seasoft's modular programs include:
Full Size Carousel (12-bottle, 5-liter shown)
Compact and Sub-Compact Carousel
Note: When using the SBE 49 with the Carousel and SBE 33, Seasave (our real-time data acquisition software) does not allow acquisition of Surface PAR data.
