EMSBK | Blast Overpressure Vibration Test Microphone | TYPE AU - 8381

EMSBK | Blast Overpressure Vibration Test Microphone | TYPE AU - 8381

Enable compliance of blasting activities

Outdoor microphone Blast Overpressure Microphone Type AU–8381, when connected to EMS Brüel & Kjær’s Vibration Monitoring Terminal Type 3680 (VMT), enables measurements of blast overpressure simultaneously with vibration to enable compliance monitoring of blasting activities around mines.

For mining staff and noise and vibration consultants measuring the impact of blasts around mines, the blast overpressure microphone, when used with the VMT, provides a durable and robust solution that, unlike many other industry-standard solutions, continues to meet the ISEE requirements even after being used for a long time in the field. In addition, the VMT with this microphone is a complete, robust and reliable blast monitoring solution that is easy to operate.

The combination fully meets the requirements of the International Society of Explosive Engineers, ISEE 2017 for ground vibration and blast overpressure monitoring.
