Part # Description Notes
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 Pressure 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 --
  • Optional 2000 psia (1300 m) sensor:
    resolution = 1 x 10 -7 * 1300 m = 0.00013 m = 0.1 mm
  • Standard 10,000 psia (6800 m) sensor:
    resolution = 1 x 10 -7 * 6800 m = 0.00068 m = 0.7 mm
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.
SBE 54 Spares & Accessories
