Description
All the industrial machines utilize working gears and members in motion which produce dynamic forces, vibrations and accelerations on the machine itself and on structures which are connected to the equipment. The ability to obtain an accurate description of the vibration by measurement and analysis can provide an invaluable contribution for gathering reliable information on the behavior of the machine under different conditions, on the working process and on the quality of the final products. By using this information effectively, it is possible to identify problems and asses their causes, evaluate the effect of proposed changes on the overall process and make meaningful decisions on the production system.

However, despite the growing awareness on the importance of this information, monitoring and detecting these often small variations has not been so far technically or economically easy to obtain. Moreover, existing systems are expensive and complex.

ADAQ has built the latest technological innovations and is able to provide a precise and reliable monitoring system. It can work as an autonomous monitoring solution in new, modern systems, be installed on old equipment or structures, replace or be integrated within existing installations. It offers high performance and reliability in a small and robust case. Due to the miniaturization of the components that build the system, the integration of different functions in a unique device and the measurement accuracy, this product is surely one of the most advanced vibration monitoring systems available on the market. The ADAQ's dual-axial Vibration Analyzer (DaVA) is a device that includes two MEMS accelerometers, one for x-axis and second one for y-axes. The accelerometer signals are then computed by a microprocessor that is integrated within the DaVA. Microprocessor performs the signal analysis and data communication functions on the basis of the uploaded application. It is programmable and fully customizable and is able to supply digital outputs. These outputs can be configured to provide an alarm signal and are logically suitable for being used as input signal by common devices, like PLC, actuators, etc.

The DaVA monitoring concept is extremely flexible because it allows to monitor and evaluate a wide range of phenomena by simply changing the installed software. A common notebook or any other computer can be used to upload programs in the DaVA internal, non-volatile memory. During normal operations, the Personal Computer operate as a graphical-user-interface, providing the ability to display waveform signals, modify filter settings and configure vibration thresholds appropriate to the working process. Once all the configuration parameters required for an application have been set, they are saved in the DaVA non-volatile memory and the computer can be removed. Indeed, the DaVA is fully capable of operating utilizing only the digital I/O without connection with the PC.
