Mini Rack

A mini rack (12” wide instead of 19”) is also available and features 7 available monitor slots instead of 14.

Like its larger counterpart, the left-most slots are reserved for the Power Supply or Supplies and TDI Module.

The mini rack may be mounted in a panel cutout or, using an optional adapter plate, on 19” EIA mounting rails.

Bulkhead mounting is not available.

The standard 3500 Rack is available in 19” EIA rail-mount, panel-cutout-mount, and bulkhead-mount versions.

The rack provides slots for two Power Supplies and a TDI in the left-most rack positions

that are reserved exclusively for these modules. The remaining 14 slots in the rack can

accommodate any combination of monitor, display, relay, Keyphasor module, and communication gateway modules.

Instrument Rack

The standard 3500 Rack is available in 19” EIA rail-mount, panel-cutout-mount, and bulkhead-mount versions.

The rack provides slots for two Power Supplies and a TDI in the left-most rack positions

that are reserved exclusively for these modules. The remaining 14 slots in the rack can

accommodate any combination of monitor, display, relay, Keyphasor module, and communication gateway modules.

All modules plug into the rack’s backplane and consist of a main module and an associated I/O module.

The I/O module installs at the rear of the rack for panel-mount systems, and above the main module for bulkhead-mount systems.

Standard rack depth is 349 mm (13.75 inches), while bulkhead mount rack depth is 267 mm (10.5 inches).

NEMA 4 and 4X weatherproof housings are available when required for environmental protection or when purge air is used.

System Components

This section describes the individual components that make up a complete 3500 system.

Proximitor Sensor

The 3300 XL NSv Proximitor Sensor has similar features to those found in the 3300 XL 8 mm Proximitor

Sensor.

Its thin design allows the user to mount it in either a high-density DIN-rail installation or a more

traditional panel mount configuration.

Improved RFI/EMI immunity allows the 3300 XL NSv Proximitor Sensor to achieve European

CE mark approvals without any special mounting considerations.

This RFI immunity also prevents nearby high frequency radio signals from adversely affecting the

transducer system.

SpringLoc terminal strips on the Proximitor Sensor require no special installation tools and facilitate faster,

highly robust field wiring connections.

The 3300 XL NSv Transducer System has an Average Scale Factor of 7.87 V/mm (200 mV/mil),

which is the most common output for eddy current transducers.

Its enhanced side-view and small target characteristics give it a shorter linear range

than the Bently Nevada 3300 XL-series 5 and 8 mm Transducer System.

The 1.5 mm (60 mils) of linear range exceeds the linear range of the 3000-series 190 Transducer System.

The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM 

Transducer Systems and the 3000-series or 7000-series 190 Transducer System.

Upgrades from the 3300 RAM system to the 3300 XL NSv system may use the existing probe, extension

cable,and monitoring system with 3300 XL NSv Proximitor Sensor.

Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, 

extension cable, and Proximitor Sensor with NSv components.

Description

The Accelerometer Mounting Kit protects an accelerometer from adverse physical and environmental conditions.

The mounting kit’s rugged design is both water-tight and dust resistant.

The mounting kit is available in three configurations to house various accelerometers.

All kits consist of a flat cover with a housing base, a set of three 1/4-in 20 UNC x 0.62 mounting screws with lock washers, a cable grip, an O-ring, and a gasket.

One configuration adds an optional dome cover. Another configuration adds an optional extension and an optional dome cover.

All kit designs mate with 12-mm (1/2-in) flexible or rigid conduit.

Properly installed kits, using an accelerometer mounting base and rigid or flexible conduit, meet API 670 requirements.

The conduit is ordered as an accessory. The mounting base is an accessory with the 23732, 330400 and 330425.

Prior to mounting, the machine surface where the housing will be installed must be spot faced.

An optional 303 stainless steel accelerometer mounting kit for extra protection in corrosive environments is also available.

It can be ordered under part number 164952-AA-BB.

Description

The 3500/62 Process Variable Monitor is a 6-channel monitor for processing machine critical parameters that merit continuous monitoring, such as pressures, flows, temperatures, and levels. The monitor accepts +4 to +20 mA current inputs or any proportional voltage inputs between -10 Vdc and +10 Vdc. It conditions these signals and compares the conditioned signals to user-programmable alarm setpoints.

The 3500/62 monitor: 

Continuously compares monitored parameters against configured alarm setpoints to drive alarms for machinery protection. l

Provides essential machine information for both operations and maintenance personnel.

You can program the 3500/62 using the 3500 Rack Configuration Software to perform either current or voltage measurements. The 3500/62 offers I/O modules for three signal input scenarios: +/-10 Volts DC, isolated 4-20 mA, or 4-20 mA with Intrinsically Safe zener barriers. The Internal Barrier I/O provides external power input terminals to provide intrinsically safe power to the 4-20 mA transducers

When used in a Triple Modular Redundant (TMR) configuration, you must install Process Variable Monitors adjacent to each other in groups of three. When used in this configuration, the monitor employs two types of voting to ensure accurate operation and to avoid loss of machinery protection due to single-point failures.

Alarms

Alarm Setpoints

User can set Alert and Danger setpoints for the value measured by the monitor. Alarms are adjustable and can normally be set from 0 to 100% of full-scale for each measured value. The exception is when the full-scale range exceeds the range of the sensor in which case the setpoint will be limited to the range of the sensor. Accuracy of alarms is to within 0.13% of the desired value. The Process Variable Monitor has both under and over alarm setpoints.

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)
