Enigma Loggers
Loggers (accelerometers)
An Enigma logger is an approximately 4.3-inch (11-cm) long by 2.4-inch (6-
cm) diameter cylinder. One end of the unit contains a powerful magnet,
which provides secure contact with ferrous materials during deployment. The
other end has an optical window through which the unit communicates with
the communications case. Each logger has an individual number for use when
deploying the loggers.
Each logger receives power from an internal battery pack, which typically
lasts 5 years. The PC software indicates low battery voltage (when
applicable) during communication activities with the loggers. When the
battery pack in a logger requires replacement, the user must return the logger
to ADS.
When necessary, the user can replace the magnet. However, please contact
ADS for instructions.
Note: When using a hydrophone, make sure a good connection exists
between the hydrophone and the pipe.
