An RSTAR System uses data
loggers (nodes) at the sensor level,
deployed in a star topology from an
active RSTAR Hub which consists
of an RST flexDAQ Data Logger.
DT LINK is an on-site wireless
connection to RST data loggers
for quick data collection. Ideal for
hard to access areas where the
data logger is within line of sight.
Above: A DT LINK WIRELESS data logger, connected to a vibrating wire piezometer
and housed in a protective enclosure, has its data collected from a laptop connected
to the DT LINK HUB - all within seconds from the convenience of your vehicle.
