SBE 9plus Housing (Depth) Selections — MUST SELECT ONE | ||
09P.1xxxxxx | Aluminum housing, 6800 m depth rating | 9plus is available for maximum depths of 6800 m (aluminum housing for main housing & T & C sensors) or 10,500 m (titanium housing for main housing & T & C sensors). SBE 5T pump is titanium, regardless of housing option, & is rated for 10,500 m.
|
09P.2xxxxxx | Titanium housing, 10,500 m depth rating | |
SBE 9plus Pressure Sensor Range (Depth Limit) Selections — MUST SELECT ONE | ||
09P.xGxxxxx | 0 - 2000 psia (1400 m) pressure sensor | ![]()
|
09P.xHxxxxx | 0 - 3000 psia (2000 m) pressure sensor | |
09P.xIxxxxx | 0 - 6000 psia (4200 m) pressure sensor | |
09P.xJxxxxx | 0 - 10,000 psia (6800 m) pressure sensor | |
09P.xKxxxxx | 0 - 15,000 psia (10,500 m) pressure sensor | |
SBE 9plus Connector Selections — MUST SELECT ONE | ||
09P.xx1xxxx | XSG/AG connectors on CTD, T&C sensors, pump, and related 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.![]() ![]() Connector on SBE 3plus Temperature Sensor with aluminum housing shown, to illustrate difference between XSG/AG & wet-pluggable connectors. |
09P.xx2xxxx | Wet-pluggable (MCBH) connectors on CTD, T&C sensors, pump, and related cables | |
SBE 9plus JT4 Connector End Cap Electronics Selections— MUST SELECT ONE | ||
09P.xxx0xxx | No electronics installed for JT4 connector, 3-pin dummy connector installed | 3-pin connector is installed for JT4, but not connected to any electronics. |
09P.xxx1xxx | Control module for GO 1015 water sampler, includes interface cables (requires water sampler modem) |
300 baud modem for water sampler control (see note) is required to support GO 1015 water sampler. With this selection in 9plus, system provides real-time control for G.O. 1015 Rosette water sampler through 3-pin JT4 connector on 9plus top end cap. *Note: 300 baud modem in 9plus & 11plus has been standard since 2005. For older instruments, it was optional. |
09P.xxx2xxx | Serial Data Uplink, 9600 unidirectional RS-232, with 9600 baud sensor communication interface (requires water sampler modem channel, limits cable length to 8,000 m, & makes 9plus incompatible with SBE 17plus Searam & other 911plus CTDs that do NOT have this option) | ![]() If 09P.xxx3x (19200 baud sensor communication) selected, continuous transmission rate may not exceed 9600 baud (960 bytes/second). Therefore, serial data output instrument must transmit at 19200 baud in burst mode (transmissions separated by intervals with no data transmission, resulting in average rate of 960 bytes/second). When 09P.xxx2x or 09P.xxx3x is ordered, JT4 connector on 9plus top end cap is a 4-pin connector. *Note: 300 baud modem in 9plus & 11plus has been standard since 2005. For older instruments, it was optional. |
09P.xxx3xxx | Serial Data Uplink, 9600 unidirectional RS-232, with 19200 baud sensor communication interface (requires water sampler modem channel, limits cable length to 8,000 m, & makes 9plus incompatible with SBE 17plus Searam & other 911plus CTDs that do NOT have this option) | |
09P.xxx4xxx | RS-232 serial output interface, installed in place of 1015 interface. 9plus data output duplicates output from SBE 11plus deck unit, except that averaging and alignment must be done in post processing. This is a custom option for AUV integration applications. A PC running Seasave will be able to display and archive CTD data directly from 9plus – no deck unit required. | This option is typically desired when an AUV / ROV is logging 9plus data. When this is ordered, 9plus transmits serial data through 3-pin JT4 connector on 9plus top end cap at 19,200 baud, 8 data bits, no parity. Power can also be supplied to 9plus through JT4 connector. |
SBE 9plus Pump Control Selections — MUST SELECT ONE | ||
09P.xxxx0xx | Pump turn-on controlled by conductivity frequency (turns on 60 seconds after conductivity frequency exceeds hardwired value); may not be suitable for fresh water applications | This selection is appropriate for most salt water applications. |
09P.xxxx1xx | Manual pump control allows user to turn pump on and off by command from Seasave software; typically used for fresh water applications |
These selections are typically used for fresh water applications:
|
09P.xxxx2xx | Water contact pump control connector allows pump to automatically turn on 60 seconds after contact pin is immersed in water (salt or fresh), and automatically turn off when contact pin is removed from water (prevents use of bottom contact switch); typically used for fresh water applications | |
SBE 9plus Temperature and Conductivity Sensor Selections — MUST SELECT ONE | ||
09P.xxxxx1x | Single T & C sensors, with TC Duct & Pump | ![]() 09P.xxxxx2x includes additional SBE 3plus temperature sensor, SBE 4C conductivity sensor, SBE 5T pump, & associated cabling, TC Duct & plumbing, & mounting. Note that secondary pump is powered via same bulkhead connector as primary pump, via included Y-cable (DN 31522 for XSG connectors, DN 32673 for wet-pluggable connectors). |
09P.xxxxx2x | Dual T & C sensors, with TC Duct & Pump | |
SBE 9plus Integration Selections — MUST SELECT ONE | ||

RS-232 serial data uplink cable, DB-9P to DB-9S, 3 m | ![]() 300 baud modem for water sampler control (see note below) & Serial Data Uplink selection in 9plus is required to support serial data uplink. Serial data is multiplexed into 9plus telemetry stream & de-multiplexed by 11plus V2, outputting to computer through standard 9600 Baud Uplink connector. System supports use of serial data output instrument & water sampler in same cast. If 19200 baud serial data uplink selected, continuous transmission rate may not exceed 9600 baud (960 bytes/second). Therefore, serial data output instrument must transmit at 19200 baud in burst mode (transmissions separated by intervals with no data transmission, resulting in average rate of 960 bytes/second). *Note: 300 baud modem in 9plus & 11plus has been standard since 2005.
