Product Features

  • Vibration and air pressure acquisition
  • Calibration of the velocity sensor according to ISEE Specification for Blasting Seismographs (USA) or to DIN 45669-1 (Germany)
  • External triaxial velocity sensor with measuring range ±250 mm/s (±10 in/s) or ±100 mm/s (±4 in/s)
  • High pressure microphone with range up to 148 dB(L)
  • Wi-Fi connectivity


The MR3003BLA is a device developed specifically for the monitoring of vibrations induced by explosions. The MR3003BLA offers 4 acquisition channels: 3 dedicated to vibrations and one to air overpressure.

The MR3003BLA devices are equipped with an embedded 4G module for wireless data transfer, and they can be linked to the SCS (Syscom Cloud Software) to offer a near real-time reporting solution with graphical norm comparison and alarming in case of norm exceedance.

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!
