SBE 16plus V2 SEACAT C-T (Pressure optional) Recorder
Configuration Details

SBE 16plus V2 is available with RS-485 interface in place of RS-232 interface; see Alternate Serial Interface Option below.

See:

• SBE 16plus-IM V2 for version with Inductive Modem interface in place of RS-232 interface.
• SBE 19plus V2 for similar CTD intended for profiling applications instead of moored applications.
• SBE 37-SM or 37-SMP MicroCAT for instrument without auxiliary sensor input capability.

SBE 16plus V2 Housing (depth) Selections -- MUST SELECT ONE

16plus V2 in plastic & titanium housings

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)

SBE 16plus V2 Digiquartz Pressure Sensor Options (substitutes for strain gauge option)

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 SBE 16plus V2 Strain Gauge Pressure Sensor Options above for photo of pressure sensor port; when used with Digiquartz, plug is replaced with nylon pressure capillary fitting.

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)

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 rated to 600 m; SBE 5M pump with titanium housing is rated to 10,500 m.

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

Data I/O - Pump bulkhead connector on 16plus V2 is standard, so pump can be added in the field without requiring any modifications to 16plus V2. These all include pump, pump mount, & data I/O - pump Y-cable. 16p-4c, -4d, -4g, & -4h include Y-cable compatible with wet-pluggable bulkhead connectors on 16plus V2 & on pump.

SBE 16plus V2 Wet-Pluggable Connector Option

MCBH wet-pluggable connectors -- photo not available

16p-5 option includes extender & data I/O cable compatible with wet-pluggable data I/O - pump bulkhead connector.

See SBE 43 specification sheet for sensor description.

SBE 43 is available in 7000 m titanium (16p-7a or -7b) or 600 m plastic (16p-7c or -7d) housing.

SBE 43 connector type (standard or wet-pluggable) must match 16plus V2 connector type.

SBE 43 is plumbed in line between conductivity sensor & pump; consequently, system requires more powerful SBE 5P plastic pump (16p-4f or -4h) or SBE 5T titanium pump (16p-4b or -4d) instead of SBE 5M pump (16p-4a, -4c, -4e, or -4g). Operational characteristics of SBE 5P & 5T are identical.

SBE 43 Mooring Configuration differs from Profiling Configuration as follows:

• Mooring configuration uses black plenum in place of white plenum, & black Tygon tubing (PN 31450) in place of clear Tygon tubing for plumbing, to reduce bio-fouling.
• Mooring configuration uses 1 mil membrane in place of 0.5 mil membrane, to enhance long-term stability.

16p-7_ includes SBE 43, 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.

Note: Sea-Bird does not supply Electrochem lithium batteries; you must purchase them elsewhere (see WGT's website for purchasing information). Shipping restrictions apply for Electrochem lithium batteries & assembled battery packs.

• 50434 for 16plus V2 with standard connectors -- See document 67196 for complete listing of parts.
• 50435 for 16plus V2 with wet-pluggable connectors -- See document 67197 for complete listing of parts.

• 4-pin end of pump-data I/O Y-cable (for 16plus V2 used with a pump), or
• 4-pin end of data I/O extension cable (for 16plus V2 used without a pump)

Connector type (standard or wet-pluggable) must match 16plus V2 connector type. Applicable cable is included with 16plus V2; these are spares.
