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
The 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, the 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, third party Functional Safety Certification can be supplied for applications requiring up to Safety Integrity Level (SIL) 2. In addition, the 3500 is approved to meet relevant Canadian Standards Association (CSA), Factory Mutual (FM), GOST, ATEX, and CE requirements.
Bently Nevada follows closely the development and changes in these standards and continually demonstrates our capacity and commitment to be in sync with them as they change and evolve. This continued focus and investment in regulatory excellence ensures our customers don’t have to worry about deploying a non-compliant solution that may later require significant update or replacement. A compliance miss has the potential for exposure to not only catastrophic consequences, but also can lead to fines from governments and inspection agencies as well as impact on insurance rates and reputation. Baker Hughes Bently Nevada is committed to continued compliance leadership and full regulatory excellence.

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 – the 3500 is the most reliable monitoring system we have ever offered with extensive self-checking and fault tolerant design features.

Connected
Connecting to condition monitoring and diagnostic software has never been easier. With the 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 Transient Data 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. Local or remote mounted displays are available, or you can operate the 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, with more than 100,000 racks installed globally.

Multiple parameters from each channel – radial vibration channels can provide eight individual parameters (overall, gap, 1X amplitude/phase, 2X amplitude/phase, Not 1X, Smax), meaning a 4-channel monitor actually provides up to 32 channels of measurements. Alarms can be set on any or all 8 parameters from each channel.

3500/15 Power supply – accepts worldwide AC/DC voltages and frequencies and can be supplied fully redundant to assure uninterrupted performance.

3500/22M Transient Data Interface (TDI) – provides configuration interface as well as single-cable connection to System 1 software via conventional wired or wireless Ethernet networks. The 3500’s advanced design ensures that simultaneous data acquisition occurs for all channels in the rack.

3500/25 Keyphasor module – accepts single- and ulti-event-per-turn signals from proximity probes and magnetic pickups. A standard rack can accommodate up to four Keyphasor signals (two 3500/25 modules), and special modifications are available when more than four Keyphasor signals are required.

Digital communications – the 3500/92 Communications Gateway supports Modbus® and Modbus/TCP protocols via serial (RS232/422/485) or Ethernet links for digital communications with PLCs, DCSs, and other instrument and automation platforms. Multiple gateways can be installed in a single rack for link redundancy or when multiple protocols are needed.

3500/05 Industry-standard 19” rack size – provides more than twice the channel density of previous systems. Available in both EIA rack and bulkhead mounting versions, along with integral (standard) or external field wiring termination blocks (optional) for maximum installation flexibility.

VGA display module – The 3500/94M VGA module displays all 3500 machinery protection system information, including:
• System event list
• Alarm event list
• All module and channel data
• Alarm and OK status
• Nine Custom display options
Supports either the 10" or 15" Advantech VGA touch screen displays. These compact, durable displays are designed for excellent viewing quality in industrial applications. The 10" Advantech display is certified for hazardous environments.

3500/40M 3500/42M Multiple parameters from each channel – radial vibration channels can provide eight individual parameters (overall, gap, 1X amplitude/phase, 2X amplitude/phase, Not 1X, Smax), meaning a 4-channel monitor actually provides up to 32 channels of measurements. Alarms can be set on any or all 8 parameters from each channel.
