2. What it does ? Continuously monitors critical industrial machinery providing information concerning wear and tear as well as the early warning of forthcoming machine failures, days or weeks in advance.

3. Operation principles eGuardian's set of sensors measures relevant parameters, like vibrations, noise, current, voltage, temperature, pressure, flow or other values depending on the application. Data is processed on site, machine state indicators are calculated and the results transferred to the local workstation. Machine state indicators are transferred to the preventive maintenance database server. Data are analyzed by the diagnostic software, machine failures are predicted and warnings are communicated to the appropriate persons and systems. Machine state indicators are archived for future use.
