RST Instruments’ Data Loggers nodes and hubs collect and store data from a wide variety of geotechnical sensors and gauges, including vibrating wire and digital microelectromechanical systems (MEMS). They can automatically collect data from the sensor outputs and can be programmed to trigger an alarm when a reading reaches a pre-set critical threshold.
Communication with data logger units can be made directly with an ethernet or USB cable or wirelessly through Wi-Fi, radio, cellular modem, or satellite modem. Your data can then be collected and analyzed in near real time, both remotely, via wireless connection to a remote workstation, and in the field, using a laptop.
The flexibility of RST Data Loggers means that they can be used in a variety of different geotechnical conditions. You will use a data logger wherever you have geotechnical measuring and monitoring instruments: water and tailings dams, mines, bridges, tunnels, open excavations, buildings, roadways, landfill sites… the list is virtually endless. Constant site monitoring is essential to keep up with and respond to the vagaries of geotechnical activity, and RST instruments provide the necessary tools for the job.
The data logging products you need will vary depending on the scope and the specifics of your project; the DT2011B Single Channel Vibrating Wire Data Logger for example, is quite specific in their collecting scope, but is fully compatible with the RSTAR Array Radio Network or DT Link Wireless Data Collection Systems.
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!
