3500 – Simply The Best

Beginning with the 5000 series in the 1960s, we’ve introduced seven successive generations of highly successful monitoring platforms. Today, that experience is embodied in the most advanced, powerful, and reliable system we have ever offered: The Bently Nevada 3500 Series Machinery Protection System.

Certified

3500 is designed to fully comply with the American Petroleum Institute’s Standard API 670, the world’s most widely used specification for machinery protection systems. For reciprocating compressor applications, 3500 meets API 618 requirements as well. It can also be ordered with DNV and Class NK certifications for maritime applications, such as offshore platforms and ship propulsion. And, when used as part of a safety instrumented system, TÜV Functional Safety Certification can be supplied for applications requiring up to Safety Integrity Level (SIL) 3. In addition, 3500 is approved to meet relevant Canadian Standards Association (CSA), Factory Mutual (FM), GOST, ATEX, and CE requirements.

Reliable

We understand that our systems are routinely used not just for indication, but to provide auto-shutdown protection. That’s why – even in simplex mode – 3500 is the most reliable monitoring system we have ever offered with extensive self-checking and fault tolerant design features. It’s also why the system can be configured with various levels of redundancy, ranging from the addition of a second fully redundant power supply to complete triple modular redundant (TMR) configuration of selected or all channels - allowing even your most mission-critical applications to be addressed with confidence.

Connected

Connecting to condition monitoring and diagnostic software has never been easier. With 3500 there are no bulky external modules, no additional wiring, and no extra rack slots required. Simply use the Ethernet port in the 3500/22M Rack Interface Module and a single network cable to communicate with our System 1* software.

Connecting to plant control and automation systems is straightforward as well. Simply add a communication gateway module. You can even add multiple gateways when communication redundancy is required or when multiple systems must be supported with differing protocols.

Flexible

The 3500 Series features the industry’s most extensive selection of machinery measurement parameters combined with software configuration for virtually all monitor options. A variety of locally or remotely mounted displays are available, or you can operate 3500 without a display. The result is unparalleled flexibility to address almost any application.

Field-Proven

The 3500 Series System has proven its value and dependability with customers everywhere, year after year. More than 20,000 racks are installed globally.

Applications

And, with our extensive custom applications capabilities, we can easily modify off-the-shelf 3500 solutions to handle your nonstandard applications and signal processing requirements.

Monitors

System Essentials These 3500 System Essentials provide the conditioned power needed to drive your rack system.	Vibration and Position As key indicators of machinery condition, vibration and position are critical to understanding how your machinery assets are performing.	Relays A variety of relay modules are available for your 3500 System to help meet the flexibility.	Keyphasor/Speed/Overspeed Monitors The 3500 Series has two choices for speed measurements.
Temperature, Pressure and Process Variable Need to measure pressure, temperature or a process variable such as flow in order to protect.	Reciprocating Compressor Monitors The 3500 Series offers a wide variety of monitors specifically designed to measure the most critical parameters on reciprocating compressors.	Aeroderivative, Hydro and Hazardous Gas Monitors Our aero-derivative and hydro monitors are top performers for collecting measurements on these unique machines.	Communication Gateways 3500's Communication Gateways get users digitally connected to a wide variety of process control systems.
Displays Want to view all the monitored parameters within the 3500 rack quickly and easily?	Accessories Harsh or hazardous environments can reek havoc on an unprotected monitoring system.
