Industries that rely on mission-critical machinery choose our machinery protection & condition monitoring

3500 Rack

The 3500 system is the world-leader at detecting and preventing both missed-trips and false-trips in rotating machinery.  It provides automatic protection value by tripping monitored machines to prevent expensive damage when needed.

The system also protects your machines and processes against false-trips that could bring your operation down for no reason, resulting in a costly outage or loss of production.

When connected with our System 1* software, it also provides continuous condition monitoring information for use in a proactive maintenance program.

The 3500 system incorporates the industry’s most extensive selection of machinery measurement parameters combined with software configuration for virtually all machinery monitoring scenarios.

Our current 3500 Condition Monitoring and Protection portfolio offers a range of options. We invite you to scroll down for more on our latest Solutions.
