AutoBlast Geophone Ground Vibration Logger


The AutoBlast is a ground vibration monitoring and logging device. It can be used in various applications of Civil Engineering such as industrial vibration monitoring, ground transportation traffic vibration monitoring, construction site monitoring, noise, and vibration monitoring in a blasting zone. It is also useful in the fields of Earthquake Engineering for monitoring the structures of buildings, bridges, and dams.

Measurement is taken using a packet of velocity sensors (geophones) and Air
Overpressure level using a microphone, storing the data into a built-in memory
storage, which can be downloaded to a PC via Bluetooth. AutoBlast™ can be
configured to perform a sensor check operation before monitoring starts to make
sure the sensors are functioning properly.

Events are automatically recorded when the measurement level of the vibration
noise exceeds a threshold value, and alarms can be raised. These can be auxiliary
alarms (i.e., light signal or siren) as well as notifications sent by Email or SMS using
the built-in modem.
