|54||Tsunameter (Tsunami pressure sensor) - Includes 10,000 psia (6800 m) Digiquartz pressure sensor (other ranges available), 128 MB Flash memory, titanium housing for 7000 m depth, RS-232 serial interface, 2.5 m data I/O cable (801385), software, & complete documentation.||
SBE 54 continuously measures & outputs pressure every
15 seconds, with a pressure resolution of better than 1 mm at full ocean
depth (7000 m). Its sole purpose is to function as heart of a deep
ocean tsunami detection system. Standard SBE 54 is externally powered.

|SBE 54 Housing Option|
|54-1||Longer housing with battery compartment for 12 D (LR-20) cells, instead of standard housing||
Standard SBE 54 is externally powered. Longer housing
provides a battery compartment for 12 D alkaline cells (LR-20) or 6
DD Electrochem lithium cells (drop-in batteries with buttons). Internal battery is diode or'ed with external
supply for use as backup to external power supply.
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.
|SBE 54 Pressure Sensor Range (depth) Options|
|54-2a||6000 psia (4000 m) Digiquartz pressure sensor instead of standard 10,000 psia Digiquartz||
sensor is installed in connector end cap, & is not field replaceable / swappable.
While highest pressure rating gives you most flexibility in using
SBE 54, it is at expense of
resolution. It is advantageous to use lowest range
pressure sensor compatible with your intended maximum operating
depth, because resolution is proportional to pressure
sensor's full scale range. For example, comparing 2000 & 10,000
psia sensors --
|54-2b||3000 psia (2000 m) Digiquartz pressure sensor instead of standard 10,000 psia Digiquartz|
|54-2c||2000 psia (1300 m) Digiquartz pressure sensor instead of standard 10,000 psia Digiquartz|
|SBE 54 Wet-Pluggable Connector Option|
|54-3||Wet-pluggable (MCBH) connectors instead of Standard (XSG/RMG) connectors on instrument & data I/O cable||
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 our standard (Impulse XSG/RMG) connectors. Like standard connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.
54-3 includes data I/O cable compatible with wet-pluggable data I/O connector.
