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.
The eNoise is a handheld, standalone portable device for the measurement and analysis of the sound pressure level emitted by a stationary vehicle. With the additional feature of an integrated internal tachometer that simultaneously monitors the acoustic signal of the exhaust to measure the engine speed, without the need of any external wiring or additional equipment.
