  • 1 hardware trigger input
  • Wireless connectivity
  • Embedded 4G module
  • Embedded Web Server for easy configuration and control


The MR3003TR is a product developed specifically for the monitoring of vibration induced by traffic and railways. The MR3003TR is based on the MR3003C, and in
addition it features a hardware trigger input and two relay outputs. This allows the user to:

  • Trigger at any time, without using the Web User Interface
  • Connect external devices to have immediate information/alarms related to vibration levels.

The MR3003TR can be delivered with an internal or an external triaxial velocity sensor MS2003+, or with three external uniaxial velocity sensors MS2003+, solution
dedicated to the traffic and railway measurements.

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!
