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.

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
