The FM 301 Blasting Seismograph, engineered by Blast Log, is a unique innovation in the field of blast monitoring technology. This state-of-the-art device, designed with the modern requirements of precision measurement and ease of use in mind, integrates tri-axial accelerometers to ensure accurate readings in any orientation, leveraging the capabilities of Micro-Electro-Mechanical Systems (MEMS) technology for superior performance.


Compact and robust, the FM 301 eliminates the complexity of external connections through its self-contained design, featuring built-in GPS for precise location tracking and Bluetooth functionality for  mobile connectivity. This design choice not only enhances operational convenience but also ensures that all necessary components for high-quality blast monitoring are enclosed within the unit itself, making it a versatile tool for field use.


Significantly, the device boasts an integrated bi-directional differential pressure transducer for air overpressure measurements, alongside its advanced MEMS accelerometers, capable of covering a wide range of vibration and pressure levels. The incorporation of both 20-bit and 14-bit analog-to-digital converters for accelerometers and the “microphone” respectively, underpins the FM 301's commitment to delivering detailed and reliable data.


With a focus on user-friendly operation, the FM 301 simplifies its usage with automatic recording mode activation upon powering on. It has the capacity to store up to 1000 events, comprising three orthogonal vibration channels, an air overpressure channel and a GPS channel. This ease of use is further enhanced by the V-Blast software, designed for straightforward data downloading and analysis, ensuring that users can efficiently manage and interpret their monitoring results.


The technological prowess of the FM 301 has been recognized and validated through extensive research by peer review involving both “Blasters in the field” and academia , with findings presented at the prestigious ISEE Annual Conference on Explosives and Blasting Technique 2023. These contributions underscore Blast Log's commitment to advancing the field of blast monitoring through rigorous scientific inquiry and technological innovation.


Powered by a low-energy, rechargeable lithium-ion battery and CE certified, the FM 301 not only aligns with environmental sustainability efforts but also meets stringent safety and performance standards. Its compact dimensions and lightweight design further enhance its portability, making it an ideal choice for professionals in the field, whether they are owners, operators, contractors or regulators involved in day-to-day blasting operations.


In summary, the FM 301 Blasting Seismograph by Blast Log is a comprehensive solution for modern blast monitoring needs, combining cutting-edge technology, user-centred design, and robust performance to support the industry's evolving requirements. Its development is backed by a foundation of validation and practical innovation, positioning it as a leader in the blasting seismograph market.
