Ground Vibration

Ground Vibration Logger

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 confi gured to perform a sensor check operation before monitoring starts to make sure the sensors are functioning properly

  1. History recording and Bluetooth capability to PC
  2. Events exceeding a threshold value are logged automatically
  3. Alarm notification: light signal or siren, as well as notifications sent by Email or SMS
  4. Built-in modem
