USS-110
from Falmouth Scientific

The Model USS-110 stress monitoring unit incorporates a 3-axis accelerometer integrated with a bi-directional high speed acoustic modem. This unique combination allows not only real-time control via down link acoustic commands, but also recovery of accelerometer and external sensor data as well as system diagnostic information. The system is housed in a 5-inch diameter aluminium pressure housing rated for 3000 meter operating depth. In addition to the 3-axis accelerometer and diagnostic data, the unit is equipped with an external connector to provide for optional processing of 5 additional channels of analog data with 12 bit resolution. This capability will allow input of sensor measurements such as strain gauges or load cells and other desired parameters. An acoustic modem is integrated, allowing for real-time data acquisition at rates up to 56K bps.

An operator interface software package is provided to allow seamless integration between the customer’s computer and the topside acoustic modem. The windows based program provides for control and display of all data acquired and for initiation of down-link commands which allow setting of the sampling interval, data averaging period, or request for continuous raw data.
