Description

The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors,

refrigeration compressors, process gas compressors, and other machines with tight installation requirements. 

The 3300 XL NSv Proximity Transducer System consists of:

• a 3300 NSv probe

• a 3300 NSv extension cable

• a 3300 XL NSv Proximitor Sensor(1)

The primary uses for the 3300 XL NSv Transducer System are for areas where counter bore,

sideview, or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems.

It is also ideal for small target applications, such as measuring radial vibration 

on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in).

It is primarily used in the following applications on fluid-filmed bearing machines where a small shaft or reduced side-view is present:

•Radial vibration and radial position measurements

• Axial (thrust) position measurements

• Tachometer and zero speed measurements

• Phase reference (Keyphasor signals)

Description

SCOUT220IS and SCOUT240IS are intrinsically safe portable data

analyzer solutions designed to monitor machinery conditions in

hazardous environments. Both are rated ATEX Zone 1 / Zone 21

(for gases and non-conductive dust) and CSA Class 1 / Div 1.

These small form-factor, rugged devices take vibration

recordings and upload the collected data for detailed analysis in System 1.

This is a two-part solution. The SCOUT data acquisition module

uses Bluetooth to communicate with a wireless, industrial

handheld device running the S1 Collector app.

Vibration recordings are viewed and stored on the handheld

device. We offer these devices with hazardous area ratings up to

Zone 1/21 & Div 1. The handheld runs the Android OS, so you can

also use it like any smartphone or tablet to take pictures and

video, send text messages, check email, make phone calls, track

your location, create SOS alerts, and run other enterprise apps.

The high performance data acquisition module provides long

battery life, yet is light & rugged. It hangs out-of-the-way on a

shoulder strap, allowing you to focus on your job and move

safely between machines. The SCOUT220IS can sample two

sensor channels simultaneously, while the SCOUT240IS supports

up to four channels. Both also support tachometer or Keyphasor

triggering. These data acquisition modules provides up to ten

hours of continuous use, while supporting an Fmax up to 80 kHz

and 12,800 lines of spectral resolution. Both models are rated

IECEx/ATEX Zone 0 / 20 (for gases and non-conductive dust) and

CSA Class 1 / Div 1.

High performance data acquisition

Unlike most products on the market,

the intrinsically safe SCOUT devices

retain the same high performance

and long battery life as their non-rated COMMTEST brethren.

Ten hours of continuous use, while supporting up to: 80

kHz Fmax, 12,800 line spectral resolution, 6-Pack super fast

measurements, 4 channel simultaneous sampling, optional

tachometer. And the firmware updates automatically from

the handheld. Amazing!

System 1 software,your plantwide solution

Use System 1* to prepare routes, analyze

data, detect long-term trends, set and

detect alarms. Then synchronize data

with your SCOUT handheld using WiFi, file

transfer, cellular network, or a USB cable. But

System 1 doesn’t stop there, it’s the same powerful package

that’s coupled with a broad range of Bently Nevada condition

monitoring and protection products. One source of the truth,

modern and plantwide.

Flexible handheld options

Choose from multiple handheld devices

to meet your form factor, screen size, and

hazardous rating needs. Update your

handheld at any time, load the System 1

Collector app onto the new device and get collecting.

So easy to carry

Carry the data acquisition module using a

shoulder strap or a belt clip. Sensors mount onto sensor

keepers. Hold the industrial smartphone or tablet in your

hand, on a belt clip, or on a neck strap. So you can focus on

your job and move safely between machines.

Powerful and connected

Vibration recordings are viewed and stored on the handheld

device. It runs the Android OS, so you can use it like any

smartphone or tablet to take pictures and video, send

text messages, check email, make phone calls, track your

location, create SOS alerts, and run other enterprise apps. Try

doing all that on an old school data collector!

Portable vibration analyzers

These portable data collector solutions record the vibration

of industrial machines, to monitor their condition and

diagnose their faults. The Series includes “SCOUT” models

for use in hazardous areas (explosive atmospheres) and

“COMMTEST” models for less stressful environments. There

are 2-channel and 4-channel versions of each, to suit your

data acquisition and analysis needs.

Designed in and for the 21st century

These two-part solutions utilize the power and

connectivity of modern industrial smartphones

and tablets, paired with a small form factor,

rugged data acquisition module. This gives the

best of both worlds, a fast handheld device full of accessories

and communication options, and a simple durable interface

to sensors on your machines.

MONITOR FUNCTIONS

SYSTEM POWER-UP INHIBIT

The System Monitor provides a Power-up Inhibit function. This function allows each monitor to

inhibit its alarms during power-up or whenever a system supply voltage falls below its operating

level. After power-up, the inhibit function remains active for approximately 2 seconds.

RACK INHIBIT

When activated by a external contact closure this function places all monitors in bypass, disables

all alarms, zero scales all outputs, and de-energizes the system OK relay. The connections for this

function are located on the power input module (PIM) at the rear of the rack.

TRIP MULTIPLY

The most common use of this function is to prevent unwanted monitor alarms during certain

conditions of machine operation. In the operation of some machinery, it is impossible to avoid

some periods of “higher than normal” vibration. Examples include startup and coastdown,

especially if the operating speed is above rotor system balance resonances (“critical speeds”),

structural and other resonances, and changes in machine load or other operating conditions.

The Trip Multiply function causes the monitor alarm setpoints (both Alert and Danger) to increase

by a fixed amount, either two times (2X) or three times (3X), according to the ordering option. Only

those monitors ordered with this option will be affected. The Trip Multiply function is performed in

the System Monitor, but is an ordering option for each monitor. It must be specified at the time of

order placement and be installed at the factory.

Trip Multiply is activated by contact closure on the PIM. A red LED on the System Monitor front

panel indicates that the Trip Multiply function is active.

Description

Relays are important to the integrity of monitoring systems. They provide

external alarm annunciation or input to an automatic shutdown device. You can

order 3300 monitors with quality, built-in relays. Installation requires no external

wiring between relays and rack, and no extra housing to mount the relays. This

facilitates installation and minimizes the chance of errors associated with field wiring.

The 3300 system offers 2 relay module types:

• Dual, with 2 relays per module

• Quad, with 4 relays per module.

For system installations on the machine deck, in hazardous areas, or in areas

with harsh environments, the dual relay module is available with hermeticallysealed relays.

For non-hazardous areas and clean environments such as control

rooms or instrument panels, modules with epoxy-sealed relays are available.

All relay modules include arc suppressors as a standard feature to increase the

life of the contacts by reducing arcing at the switching point.

Installation Checklist

Use the following items to plan a 3500 rack installation:

• What are the power requirements?

• Does the rack fit in the proposed location?

• Can you mount the rack in the proposed location?

• Does the proposed location provide enough air circulation?

• Does the rack require a weatherproof housing?

• What termination does the rack require (internal or external)?

• Does the rack require a telephone line?

• Does the location provide good grounding for the rack?

• If you plan to fit Internal Barriers, does the location provide an Intrinsically Safe Earth?

Weatherproof Housing Installation

This section describes the 3500 weatherproof housing and provides instructions for proper installation.

General Description

The 3500/06 weatherproof housing is an enclosure designed to meet NEMA 4 requirements and to contain

one 3500 series rack (rack mount option only). The housing design does not accommodate a Display Unit or VGA display.

The housing is available in painted steel or stainless steel versions, with or without conduit fittings, and with or without air purge accessories.

A hinged door provides access to the front of the rack. A bolt-on cover provides access to the rear of the rack.

To provide Intrinsically Safe (IS) vibration and process variable monitoring,

the 3500 system has a range of I/O modules with internal zener barriers.

When you install these modules in a 3500 rack with a 3500/04-01 Earthing Module, 

they provide an integrated solution for explosion protection for approved Bently Nevada

transducer systems that are located within all classifications of hazardous areas (surface industries other than mining).

3500 Internal Barrier System Restrictions

• You must install 1 earthing module in each rack in the internal barrier system. 

The earthing module occupies 1 slot position in the rack when it uses Internal Barrier I/O modules.

• You must change the grounding configuration of the 3500/15 Power Supplies from the default factory setting.

See the 3500/15 Operation and Maintenance Manual (PN 129767-01) for instructions.

• You must isolate any RS-232 connection to any 3500 module. Monitors that support RS232 connections include Rack Interface Modules, 

Communication Gateways, and the 3500/95 PC Display. See the 3500/20 Operation and Maintenance Manual (PN 129768-01) for instructions.

This restriction does not apply to RS422 and RS485 connections to the rack. 

Monitors that support RS422 and/or RS485 connections include the 3500/20, 3500/90, 3500/92, 3500/93, and 3500/95.

• You must not use the 3500/94 VGA Display in internal barrier systems.

• You must not use bussed transducers, as internal barrier systems do not allow bussed transducers. See the TMR section of this manual for more information.

3500 Internal Barrier System Features

• The earthing module supports dual IS Earth connections for cables with cross-sectional areas up to 10 mm2. This module lets you test IS Earth continuity online.

• The design of the internal barrier I/O modules provides the 2 inches (50 mm) of separation required between safe and hazardous area field wiring.

• The connectors for safe areas and hazardous areas have different field wiring colors (green for safe and blue for hazardous) and connector pitches. 

This helps to avoid incorrect field wiring installation.

• Quick connect/disconnect connectors simplify field wiring installation and removal.

• You can locate standard and internal barrier I/O modules in the same 3500 rack. 

We recommend that you group the modules together as shown in Figure 2-10 to facilitate connection to field wiring.
