BLASTING MONITORING SYSTEM
The MR3003BLA is a family of instruments dedicated to the monitoring of explosioninduced vibrations. The three channels for vibration and the channel for air overpressure make them perfect for a complete blasting monitoring.
The MR3003BLA devices are equipped with an embedded 4G module for wireless data transfer, and they can be linked with the SCS (Syscom Cloud Software) to offer a near real-time reporting solution with graphical norm comparison and alarming in case of
norm exceedance.
NORM COMPLIANCE
The MR3003BLA devices have been designed based on the ISEE Performance Specification for Blasting Seismographs and they can be used to evaluate blast-induced vibrations according to the following norms among others:
- RI 8507 & OSM Regulation (USA)
- AS 2187-2 (Australia)
- DIN 4150-3 (Germany)
- BS 7385-2 (UK)
- Arrêté du 1994 (France)
- UNE 22-381 (Spain)
The MR3000BLA in aluminium case (or simply MR3000BLA-alu) is the new device of the MR3000BLA family, built in an aluminium case.
It is dedicated to long-term monitoring in blasting applications. Its main features are:
- 4 channels for external triaxial velocity sensor and overpressure microphone
- Compact case derived from MR3000C
- Embedded 3G module
- Wi-fi and LAN connection
- Optional GPS antenna
- Optional mounting plate for direct installation of the microphone rod
- Compatibility with SCS (Syscom Cloud Software)
- API REST interface available on request. Feel free to contact us for more information.
