DST Pitch
& Roll Logger
Small submersible pitch and roll
logger with additional temperature and depth sensors
Overview:
Sensors: Pitch and Roll, Temperature and Depth
Memory size: 174.600 measurements in total
Battery life: 5 years
Depth: Down to 3000m
Application examples:
- For analysing fish movements/orientation in relation to
buoyancy (gas in/out from swimming bladder).
- Analysing fish target strength in acoustic surveys in
relation to their behaviour and orientation, for improving
biomass estimations.
- Finding pattern in fish behaviour, diurnal/seasonal, for
improving acoustic surveys estimation of biomass.
- Analysing orientation of trawl doors and other fishing gear.

The DST pitch and roll measures additionally to temperature and
depth, relative pitch and roll movements of the DST, with reference to
the earth gravity. The measuring parameters are measuring the gravity
movements in two directions:
The picture shows the measuring directions of the sensor relative to
the DST housing.
The DST pitch and roll tag allows the scientist to take frequent
sampling of the orientation of fish using different sampling
intervals. Measuring resolution is better than 1°.
The sensor can be used for analysing movements of marine animals as
well as various underwater gear. For analysing fish movements, it is
advised to fasten the tag at both ends for avoiding / limiting
movements of the tag. The tag has a measuring range of approximately
+/- 80° in each direction.
Easy to use
DST centi series is supported by the SeaStar software for Windows, and
a communication box which connects to a PC computer. All
communications and data transfer is wireless via the communication
box. DST is inserted into the box for establishing communication,
using the SeaStar software. Before use of the DST, the user sets the
sampling interval and start time of recordings. After recapture of
DST, the data is retrieved to a PC computer, using the
communication box and
SeaStar software. The logger can be re-programmed and reused as
long as battery lasts.
How to Order
When you have found the product that you are interested in please
Contact Us and ask
for a quote, or send an inquiry about the product.
As a start kit, you
need one or more DST loggers, one
communication box and the
supporting software (SeaStar). We also offer
protective housing for the loggers if the loggers are going to be
used in fixed locations or in harsh environment.
Star-Oddi employs very competent employees with many years of
experience in electronic engineering and sales of scientific equipment
for various research applications. The more information you can give
us we are more likely to help you find the right product.
