Telesonar Underwater Acoustic Modems
|
| Topside ATM-871
The ATM-891 topside modem and ATM-880 modem module serve as
the surface components of the bi-directional acoustic communication
system. These surface modems, configured with a remote dunking
transducer, transmit commands/data to, and receive commands /data
from, the subsea acoustic modem(s) located on a seafloor
instrumentation package or AUV.
The ATM-891 is housed in a standard deck box that is ideal for boats,
dockside applications, and other real time environments. The unit
operates with AC/DC power and includes a speaker, serial port, and
transducer cable connector – all in a splash proof case.
The ATM-880 is housed in a NEMA enclosure and is ideal for buoy or
remote deployment applications. There is space for RF radio modem.

introduced in the SMART product line. Similar to the TR-6000, a proven
Benthos acoustic transponder, the electronics, batteries and a
transducer are housed in a glass sphere with a burn wire release
mechanism. This self-buoyant modem however offers much more
capabilities for the user. The glass sphere contains the modem PCB
which allows the user full telemetry capability to full ocean depth,
with RS-232 connectivity to attached sensors. The SM-75 may operate
independently or can function as a node in a small network.
|
|
| SR-100
The SMART Release is a unique concept from Benthos that
combines the proven technology of an underwater acoustic release with
the reliable undersea communications functionality of an acoustic
modem. When deployed, the unit can be connected to an underwater
sensor such as a Conductivity Temperature and Depth recorder (CTD),
acoustic Doppler profiler, or other devices. The SMART Release unit
can then acoustically transfer data from the device to which it is
connected up to the surface or to another sub sea unit and later be
retrieved. This new device will allow oceanographic, military and
other users the ability to monitor and retrieve data from their sub
sea instruments and release the entire package of instruments
successfully to the ocean’s surface at a later date.

Floatation
|
Glass Spheres
|
| Glass Spheres
Teledyne Benthos patented VacuSealed® glass floats and instrument
housings are manufactured from precision-molded spheres to exact
specifications. The edge of each hemisphere is ground flat to extreme
tolerances. When used for flotation the hemispheres are matched,
mated, and then evacuated to an absolute internal air pressure of less
than 0.3 atmospheres. After evacuation, a sealant and protective tape
are applied around the equator. Spheres sealed in this method are
nearly impossible to open due to the force exerted upon them by the
atmospheric pressure. In the case of the 43.2 cm (17 in) diameter
float, this force is in excess of 880 kg (2000 lbs).
