Bently Nevada Asset Condition Monitoring

Why protect
and monitor?

Whether generating power, compressing and pumping
fluids, or driving process equipment, industries rely 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

Reduced insurance premiums

And when it comes to protecting and monitoring critical
machinery, one name has proven itself above all others:
Bently Nevada

3500 – Simply the best

Monitor modules

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
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.
