Bently Nevada has a legacy of machinery protection and condition monitoring. Bently Nevada's product line is capable of monitoring for the protection and continuous monitoring of varied machinery assets. The Bently Nevada 3500 System provides continuous, online monitoring suitable for machinery protection applications and collect machine information as a part of comprehensive predictive maintenance program for both field diagnostics and test stand use.

Whether generating power, compressing and pumping fluids or driving process equipment, industry relies on critical machinery every hour of every day. In these settings, machinery failure isn’t just inconvenient, it can be catastrophic. While repair costs alone can be staggering, the partial or even total loss of production resulting from critical machinery failure – sometimes worth millions per day – can mean the difference between profit and loss for the entire year. With so much at stake, mechanical condition monitoring is more than just a good idea, it’s a necessity.

Continuously monitoring critical asset parameters such as vibration, temperature, speed, and numerous other condition indicators is a proven method for anticipating and preventing mechanical failures – proven in tens of thousands of industrial facilities around the world by delivering tangible benefits such as:

  • Improved protection from catastrophic failures
  • Better machinery reliability/availability
  • Fewer process interruptions
  • Enhanced maintenance/outage planning
  • Lower maintenance and repair costs
  • Longer intervals between outages


The enormous selection of measurement types available in 3500. This allows it to be applied to an extremely wide range of rotating and reciprocating machinery in many industries. Below are just a few of the more common applications that can be easily addressed by the 3500 System.

  • Steam turbines
  • Hydraulic turbines
  • Industrial gas turbines
  • Aeroderivative gas turbines
  • Reciprocating compressors
  • Centrifugal compressors
  • Axial compressors

Diagnostic Software

Protecting your critical machinery with 3500 is an important step. But there’s more to effective asset management than just protection. The combination of 3500 and System 1 software provides your critical machinery with today’s most advanced technology to proactively detect and avoid problems. When a specific malfunction or condition is detected, System 1 software alerts plant personnel that there is a problem, how severe it is, and what to do about it – in real time. The Actionable Information messages used to notify plant personnel are fully configurable, reflecting your specific operating practices and procedures.
