MR3003SB
The MR3003SB is a dedicated seismic monitoring system for structures and buildings. Its compactness with all must-have features already integrated makes it an ideal motion recorder for any type of structure, tailor-made for buildings.
Overview
The MR3003SB seismic monitoring system is the most advanced, integrated, and reliable monitoring system for structures and buildings, able to automatically detect,
record, and process any strong motion vibrations that might affect the structure. A daisy-chained network (Fiber Optic or Ethernet Copper cable) coupled with the latest data
retrieval capabilities, make the MR3003SB the easiest to use and most versatile instrument available on the market.
The all-in-one Red Box with an internal battery, AC/DC, and terminals already integrated provides all the necessary features for easy installation without any additional
parts. Command & control access through an embedded web server provides a self-explanatory interface for system set-up and control.
The optional kit with 3 configurable relay outputs (alarm 1, alarm 2, device error) can be directly connected to any external alarming devices and used as an earthquake
early warning system. A common logic system, for a typical 3-station network, will ensure the highest reliability and avoid spurious activation of the warning system.

Speak with an Expert
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!
