DT2485 DT-Bus Data Logger
The DT2485 enables low cost, stand alone, and radio-linked data collection of In-Place Inclinometer Strings and other digital bus (DT-BUS) sensors.
Overview
Overview
DT-BUS sensors/instruments can be incorporated into a wireless, or stand alone, data collection system by using the DT2485 Data Logger. The DT2485 provides wireless transmission of data collected from the DT-BUS sensors to an RSTAR Hub in a fixed location, or to a portable hub in a DT LINK System. More information on the RSTAR and DT LINK wireless data collection options can be found by viewing their separate brochures at rstinstruments.com.
DT-BUS instruments feature a single cable running the length of an entire chain of connected sensors/instruments, which are all individually addressable. As a result, DT-BUS simplifies installation and minimizes costs by eliminating the need of a separate cable for each sensor and also reduces the amount of cable to be managed during installation. The DT2485 also supports MODBUS sensors.
The DT2485 Data Logger can also be used with DT-BUS sensors where wireless data collection is not required. A string of up to 56 biaxial DT-BUS sensors can be read by the DT2485. The DT2485 can also be upgraded with an optional radio kit and antenna to incorporate it into an RSTAR, RSTAR Affinity, or DT LINK wireless system (see separate brochures)
