Cutting edge technology

CUTTING EDGE TECHNOLOGY

The FM 301 utilise tri-axial accelerometers as an alternative to standard geophones.
This allows the unit to be lightweight and can be orientated in any direction.

LET'S CHAT

INTEGRATED GPS

All FM 301 units include a GPS receiver as standard.
This allows the user to know where monitoring was carried out*.
The GPS co-ordinates are written into the recorded file.

* GPS satellite signals are too weak to reach indoors and as such
they don't always perform well in indoor settings

Technology validation

In order to validate the innovative technology used in the FM 301 seismographs, a series of academic papers were submitted to International Society of Explosives Engineers (ISEE) and approved.

Both papers were presented earlier this year at ISEE Annual Conference on Explosives and Blasting Technique 2023.
