SBE 16plus V2 SeaCAT CT(D)

SBE 16plus V2 SeaCAT CT(D)
The SBE 16plus V2 SeaCAT is a high-accuracy conductivity and temperature (pressure optional) recorder designed for moorings or other long-duration, fixed-site deployments. It supports numerous auxiliary sensors (dissolved oxygen, pH, turbidity, fluorescence, oil, PAR, etc.) with six A/D channels and one RS-232 data channel. The 16plus V2 communicates via an RS-232 serial interface, and has internal batteries and memory. It is well suited to networked sensor arrays where its operation can be triggered by satellite, radio, or hardwire telemetry equipment.

Data is recorded in memory and can also be output in real-time in engineering units or raw HEX. Battery endurance varies, depending on the sampling scheme; nine alkaline D-cells provide power for 355,000 samples of C and T.

FEATURES
• Moored Conductivity, Temperature, Pressure (optional), and up to seven auxiliary sensors, at user-programmable intervals (10 seconds to 4 hours).
• RS-232 interface, internal memory, and internal alkaline batteries (can be powered externally).

SBE 16plus V2 Housing (depth) Selections MUST SELECT ONE
16P.1xx0x 600 m plastic housing  
16P.2xx0x 7000 m titanium housing  
16P.3xx0x 10,500 m titanium housing  
SBE 16plus V2 Pressure Sensor Selections MUST SELECT ONE
16P.x0x0x No pressure sensor Pressure sensor is installed in connector end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using 16plus V2, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to pressure sensor's full scale range. For example, comparing 2000 & 7000 m sensors:
  • 2000 m sensor:
    initial accuracy = 2 m (= 0.1% * 2000 m),
    resolution = 0.04 m (= 0.002% * 2000 m)
  • 7000 m sensor:
    initial accuracy = 7 m (= 0.1% * 7000 m),
    resolution = 0.14 m (= 0.002% * 7000 m)
16P.x1x0x 20 m strain gauge pressure sensor
16P.x2x0x 100 m strain gauge pressure sensor
16P.x3x0x 350 m strain gauge pressure sensor
16P.x4x0x 600 m strain gauge pressure sensor
16P.x5x0x 1000 m strain gauge pressure sensor
16P.x6x0x 2000 m strain gauge pressure sensor
16P.x7x0x 3500 m strain gauge pressure sensor
16P.x8x0x 7000 m strain gauge pressure sensor
16P.x9x0x 10,500 m strain gauge pressure sensor
16P.xAx0x 45 psia (20 m) Digiquartz pressure sensor with temperature compensation Digiquartz pressure sensors provide better accuracy (0.02% of full scale range vs 0.1% of full scale range) & resolution (Digiquartz resolution dependent on user-programmable integration time) than strain gauge pressure sensors. See strain gauge options above for photo of pressure sensor port; when used with Digiquartz, nylon pressure capillary fitting screws into port.

Pressure sensor is installed in connector end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using 16plus V2, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to pressure sensor's full scale range. For example, comparing 2000 psia (1400 m) & 6000 psia (4200 m) sensors:

  • 2000 psia (1400 m) sensor:
    initial accuracy = 0.28 m (= 0.02% * 1400 m)
  • 6000 psia (4200 m) sensor:
    initial accuracy = 0.84 m (= 0.02% * 4200 m)

16P.xKx0x 15,000 psia (10,500 m) Digiquartz pressure sensor with temperature compensation
SBE 16plus V2 Connector Selections MUST SELECT ONE
16P.xx10x XSG/AG connectors on SeaCAT bulkhead connectors and on extender and data I/O cables

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.

 
These selections include extender & data I/O cable compatible with data I/O - pump bulkhead connector.

16P.xx20x Wet-pluggable (MCBH) connectors on SeaCAT bulkhead connectors and on extender and data I/O cables
SBE 16plus V2 Submersible Pump Selections MUST SELECT ONE
16p.xxx00 No pump

SBE 5M pump is intended for providing pumped conductivity only. Pump provides better conductivity response & anti-foulant protection than non-pumped configuration. SBE 5M pump with plastic housing is supplied for 16plus V2 with 600 m housing; SBE 5M pump with titanium housing is supplied for 16plus V2 with 7000 or 10,500 m housing.

Larger, more powerful SBE 5P or 5T is required if also planning to pump auxiliary sensors (such as dissolved oxygen, etc.). Operational characteristics of SBE 5P & 5T are identical. SBE 5P plastic pump is supplied for 16plus V2 with 600 m housing; SBE 5T titanium pump is supplied for 16plus V2 with 7000 or 10,500 m housing.

Data I/O - Pump bulkhead connector on 16plus V2 is standard, so pump can be added in field without requiring any modifications to 16plus V2. SBE 5M or 5P/5T selection includes pump (with same connector type as 16plus V2), pump mount, & data I/O - pump Y-cable (cable compatible with connectors on 16plus V2 and pump). See cable DN 31551 for XSG/AG connectors, DN 32896 for wet-pluggable connectors.

16p.xxx02 Add SBE 5P/5T pump for sensor flushing
SBE 16plus V2 Dissolved Oxygen Sensor Options
16p-7g SBE 63 Optical Dissolved Oxygen Sensor, with XSG connector, 600 m (cable & mount included, requires 16p-4f or -4b & 16P.xx10) SBE 63 is available in 600 m (16p-7g or -7h) or 7000 m titanium (16p-7e or -7f) housing, and its connector type (XSG or wet-pluggable) must match 16plus V2 connector type.

SBE 63 is plumbed in line between conductivity sensor & pump; consequently, system requires more powerful SBE 5P plastic pump or SBE 5T titanium pump instead of SBE 5M pump. Operational characteristics of SBE 5P & 5T are identical.

All 16p-7 options include SBE 63, mount, & straight cable to connect sensor to 16plus V2 bulkhead connector. If connecting 2 sensors to 1 bulkhead connector, extra charge to substitute Y-cable applies in addition to 16p-7_ price.

Additional sensors not listed here — fluorometers, transmissometers, turbidity meters, PAR sensors, etc. from third party manufacturers — are compatible with 16plus V2. These sensors can be purchased from Sea-Bird & integrated with 16plus V2 at our factory, or you can purchase mount kits & cables from Sea-Bird & perform integration yourself. See Third Party portion of price list.

SBE 16plus V2 Spares & Accessories
801542 AF24173 Anti-Foulant Device pair (spare, bagged, labeled for shipping) Anti-foulant devices fit into anti-foulant device cups at each end of conductivity cell. Anti-foulant devices included with standard shipment; these are spares.
Useful life varies, depending on several factors. We recommend that customers consider more frequent replacement when high biological activity & strong current flow (greater dilution of anti-foulant concentration) are present. Moored instruments in high growth & strong dilution environments have been known to obtain a few months of quality data, while drifters that operate in non-photic, less turbid deep ocean environments may achieve years of quality data. Experience may be strongest determining factor in specific deployment environments.
