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

See SBE 37-SM or 37-SMP MicroCAT for instrument without auxiliary sensor input capability.

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

16plus in standard plastic & optional titanium housings

• 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 Digiquartz Pressure Sensor Options (substitutes for strain gauge option)

Pressure sensor is installed in connector end cap, & is not field replaceable / swappable. While highest pressure rating gives you most flexibility in using 16plus, 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)

Auxiliary sensors (dissolved oxygen, fluorometer, transmissometer, etc.) plug into bulkhead connectors on 16plus connector end cap.

• 16p-3a provides 2 bulkhead connectors, each supporting 2 differential A/D channels (differential A/D channel is differentially amplified to reject noise).
• 16p-3b provides 1 bulkhead connector for 2 differential A/D channels, 1 bulkhead connector for third differential A/D channel, & 1 bulkhead connector for PAR sensor.
• 16p-3c provides 2 bulkhead connectors, each supporting 2 differential A/D channels, & 1 bulkhead connector for an RS-232 sensor (SBE 38 temperature sensor, SBE 50 pressure sensor, or Gas Tension Device).

Note: 16p-3a, -3b, & -3c do not include auxiliary sensors, mounts, or interface cables.

• See SBE 16plus Dissolved Oxygen Sensor Options below for ordering and integrating SBE 43 DO Sensor with 16plus.
• See Third Party portion of price list for ordering details on fluorometers, transmissometers, turbidity meters, PAR sensors, etc. that are compatible with 16plus. These sensors can be purchased from Sea-Bird & integrated with 16plus at our factory. Alternatively, you can purchase sensors from third party manufacturers, purchase mount kits & cables from Sea-Bird, & perform integration yourself.

User can change sensors on 16plus in field, if combination is compatible with auxiliary channel configuration selection. However, bulkhead connector(s) that support 2 differential A/D channels each require Y-cables to connect auxiliary sensors to 16plus; each Y-cable is unique to sensors being integrated, so changing sensors may require changing Y-cable. In addition, sensor mechanical mountings may need to be changed to suit selected combination of sensors.

SBE 5M pump is intended for providing pumped conductivity only. Pump provides better conductivity response & anti-foulant protection than non-pumped configuration. Larger, more powerful SBE 5T is required if also planning to pump auxiliary sensors (such as dissolved oxygen, etc.).

Pump bulkhead connector on 16plus is standard, so pump can be added in the field without requiring any modifications to 16plus. These all include pump, pump mount, & pump interface cable. 16p-4c & 4d include pump cable compatible with wet-pluggable bulkhead connectors on 16plus & on pump.

Pump (SBE 5M or 5T) is titanium, regardless of 16plus housing option, & is rated for 10,500 m.

SBE 16plus Wet-Pluggable Connector Options

16p-5_ options include data I/O cable compatible with wet-pluggable data I/O bulkhead connector.

• 16p-5a requires 16p-3a (4 A/D channels).
• 16p-5b requires 16p-3b (3 A/D & 1 log amp channel).
• 16p-5c requires 16p-3c (4 A/D & 1 RS-232 channel).

See SBE 43 specification sheet for sensor description.

Mooring Configuration differs from Profiling Configuration as follows:

• Mooring configuration uses black plenum in place of white plenum, and 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.

SBE 43 connector type (standard or wet-pluggable) must match 16plus connector type. SBE 43 is plumbed in line between conductivity sensor & pump; consequently, system requires more powerful SBE 5T pump (16p-4b or -4d) instead of 5M pump (16p-4a or -4c).

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

16p-7_ includes SBE 43, mount, & straight cable to connect sensor to 16plus 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. These sensors can be purchased from Sea-Bird & integrated with 16plus 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.
