Adash America A3812 - 12 Channel A3800 Compact On-Line Monitoring

Set up and control

The setup and control of the A3800 is done by the DDS software. The set up has never been easier. The only thing you need to do is to create the tree of machines, measurement points, and required readings and assign them to appropriate channels. Then you just press START and the readings are taken automatically.

The new data acquisition control system was developed for the A3716 and A3800 systems. Now the units read the vibration continuously, not only at predefined time intervals. The adaptive algorithm saves the readings to the database.

The A3800 unit continuously monitors the required machines and adaptively saves the readings to the data storage computer. The data is accessible from various workstations for control and analysis.

The great advantage of the DDS software is its very easy set-up. There is no difficult installation of the server anymore and no complicated set-up of parameters. The demands for transfer and data storage are minimized.
