Condition monitoring with Valmet DNA

DNA Machine Monitoring measures and analyzes the mechanical condition and performance of machinery units, based on vibration measurements and other machine parameters. DNA Machine Monitoring provides both protection and diagnostics for critical machinery, as well as condition monitoring and analyzing tools for the predictive maintenance of auxiliary machinery.

Online machine condition monitoring enables 24/7 monitoring, thus providing the fastest possible way to act on problems and to secure safe sailing, protect assets and increase working environment safety. DNA Machine Monitoring can work as a fully integrated application in the Valmet DNA automation platform or as a stand-alone system.

Online machine condition monitoring is based on fixed installed sensors on the machinery, cabled to remote I/O stations where measurement data is collected in real time for critical machinery and cyclic intervals for auxiliary machinery. Alarms are generated when pre-set alarm limits are exceeded. Fault analyzing is performed with comprehensive signal analyzing tools. Defect development is monitored by tracking historic trends, thereby providing the tools for predictive maintenance and for scheduling service.


Machine condition monitoring enables the detection of mechanical faults like

• bearing wear and instabilities
• unbalance
• misalignment
• thrust bearing wear
• shaft defects
• wear and looseness
• gear mesh problems
• resonances
