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.

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.

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.

Experience

With more than six million transducers and monitoring

channels installed worldwide, more end users trust their

machinery to Bently Nevada’s continuous monitoring

systems than anyone else. We are also the supplier of choice

to nearly every major machinery manufacturer in the world.

Technology

Today, although our products number in the thousands, we

never rest. Each year, tens of millions of dollars are invested in

expanding and improving our technology with the purpose of

better serving our customers. Better technology that creates

better value is our passion.

the highest quality, best value in the industry is born of a

culture that “takes excellent care of our customers.” When

you choose our condition monitoring solutions, you get it all:

the best people, the best products; the best service; the best

solutions – together generating the best value.

For more than half a century, Bently Nevada products have

been world-renowned as the standard by which all others

are measured. Because after all, with so much riding on your

machinery, why trust anyone else?

Series Machinery Protection System:

• Universal AC Power

• High Voltage DC Power Supply

• Low Voltage DC Power Supply

The Universal AC Power Supply and PIM (Power Input Module)

are not compatible with the Legacy 3500 AC Power Supply,

High Voltage AC PIM and Low Voltage AC PIM.

The High Voltage and Low Voltage DC Power Supplies and

PIM(Power Input Module) are NOT compatible with the Legacy

3500 High Voltage and Low Voltage DC Power Supplies and PIMs.

The 3500/15 AC and DC Power Supplies are half-height modules and

must be installed in designated slots on the left side of the rack. The

3500 rack can contain one or two power supplies with any combinations

of AC and DC. Either supply can power a full rack.

When two power supplies are installed in a rack, the one in the lower

slot acts as the primary supply, and the other in the upper slot acts as

the backup supply. If installed, the second supply is the backup for the

primary one.

Description

The 3500/15 AC and DC Power Supplies are half-height modules and

must be installed in designated slots on the left side of the rack. The

3500 rack can contain one or two power supplies with any combinations

of AC and DC. Either supply can power a full rack.

When two power supplies are installed in a rack, the one in the lower

slot acts as the primary supply, and the other in the upper slot acts as

the backup supply. If installed, the second supply is the backup for the

primary one.

Removing or inserting either power supply module does not disrupt

operation of the rack as long as a second power supply is installed.

The 3500/15 AC and DC Power Supplies accepts a wide range of input

voltages and converts them to voltages acceptable for use by other

3500 modules.

Description

The 3500/65 monitor provides 16 channels of temperature

monitoring and accepts both resistance temperature

detector (RTD) and isolated tip thermocouple (TC)

temperature inputs.  The monitor conditions these inputs and

compares them against user-programmable alarm

setpoints.

The monitor is programmed using the 3500 Rack

Configuration Software.  You can configure the 16-Channel

Temperature Monitor to accept isolated tip thermocouples,

3-wire RTD, 4-wire RTD, or a combination of TC and RTD inputs.

In Triple Modular Redundant (TMR) configurations, you must

install temperature monitors in groups of 3 adjacent

monitors. In this configuration the monitor uses 2 types of

voting to ensure accurate operation and to avoid single

point failures.

Display Brightness

The brightness of an LCD display is the amount

of light emitted and is measured in nits or

candelas per square meter, which has units of

nits or cd/m2. Most commercial desktop

displays have a brightness of 200 to 300 nits. To

see a display in outdoor light requires a

brightness of about 700 nits or greater. Almost

all new LCD displays use some form of white or

RGB LED backlight.

Some of the brighter displays can have

a half-life of 20.000 hours or less.

Bright Idea: The brightness life of the display

can be dramaticallyincreased and burn-in can

be mitigated by allowing the screen saver to

dim and/or turn off the display when not in use.

Display Brightness Half-Life

An important characteristic of an LED backlight

is the brightness half-life, which is the time

measured in hours that the brightness output

will decrease by half after running the LED

backlight at full brightness. The decrease in

brightness will not substantially decrease after

the half-life time has elapsed. Most displays

have a half-life of around 50.000 hours (or 5.7

years). Some of the brighter displays can have

a half-life of 20.000 hours or less.

Bright Idea: The brightness life of the display

can be dramaticallyincreased and burn-in can

be mitigated by allowing the screen saver to

dim and/or turn off the display when not in use.

Touchscreen Display Support

Orbit Display uses a touchscreen display. You

can show data from up to twelve Orbit 60

chassis connected via Ethernet on a single

Orbit Display.

If necessary, Bently Nevada can produce

custom drivers for specific displays and

pointing devices. For assistance, or for a list of

supported displays and required drivers,

contact Bently Support at Bently.com/support.

The Orbit Display is backwards compatible  with

the existing 10.4″ and 15″ displays currently

supported by the 3500 system:

Supported Displays

120M8155-01  10.4” 640×480 Hazardous Location Display

102M8950 15” 1024×768 Hazardous Location Display

150M1466  21.5” 1920×1080 Industrial Display

Display Burn-in or Ghosting

All display technologies are susceptible to

burn-in or ghosting, which occurs when static

and cumulative non-uniform pixel use

discolors areas on a screen. Burn-in can be

noticed when the display changes and when

the display is turned off.
