Specifications and Ordering InformationPart Number 141194-01Rev. T (12/12)Bently Nevada* Asset Condition Monitoring 3300 XL 8mm Proximity Transducer SystemDescription The 3300 XL 8 mm Proximity Transducer System consists of: ∙ One 3300 XL 8 mm probe,∙ One 3300 XL extension cable 1, and ∙ One 3300 XL Proximitor * Sensor 2. The system provides an output voltage that is directly proportional to thedistance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor * reference and speed measurements 3.The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-metre system also fully complies with the American Petroleum Institute’s (API) 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual componentsEach 3300 XL 8 mm Transducer System component is backward-compatible and interchangeable 4 with other non-XL 3300 series 5 mm and 8 mm transducer system components 5. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space 6,7.Proximitor SensorThe 3300 XL Proximitor Sensor incorporates numerous improvements overprevious designs. Its physical packaging allows you to use it in high-density DIN-rail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older Proximitor Sensor designs. The mounting base for either option provideselectrical isolation and eliminates the need for separate isolator plates. The 3300 XL Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings, resulting in lower installation costs and complexity. The 3300 XL’s SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.Proximity Probe and Extension CableThe 3300 XL probe and extension cable also reflect improvements over previous designs. A patented TipLoc* molding method provides a more robust bond between the probe tip and the probe body. The probe’s cable incorporates a patented CableLoc* design that provides 330 N (75 lbf) pull strength to more securely attach the probe cable and probe tip. You can also order 3300 XL 8 mm probes and extension cables with an optional FluidLoc* cable option. This option prevents oil and other liquids from leaking out of the machine through the cable’s interior.ConnectorsThe 3300 XL probe, extension cable, and Proximitor sensor have corrosion-resistant, gold-plated ClickLoc* connectors. These connectors require only finger-tight torque (the connectors will "click" when tight), and the specially-engineered locking mechanism prevents the connectors from loosening. These connectors require no special tools for installation or removal.You can order the 3300 XL 8 mm probes and extension cables with connector protectors already installed. We can also supply connector protectors separately for field installations (such as when an application must run the cable through restrictive conduit). We recommend connector protectors for all installations to provide increased environmental protection8.Extended Temperature Range ApplicationsAn extended temperature range (ETR) probe and ETR extension cable are available for applications in which either the probe lead or extension cable may exceed the standard 177 ︒C (350 ︒F) temperature specification. The ETR probe has an extended temperature rating for up to 218 ︒C (425 ︒F). The ETR extension cable rating is up to 260 ︒C (500 ︒F). Both the ETR probe and cable are compatible with standard temperature probes and cables, for example, you can utilize an ETR probe with the 330130 extension cable. The ETR system uses the standard 3300 XL Proximitor Sensor. Note that when you use any ETR component as part of your system, the ETR component limits the system accuracy to the accuracy of the ETR system. Description Notes:1.1-metre systems do not use an extension cable.2.Proximitor sensors are supplied by default from thefactory calibrated to AISI 4140 steel. Calibration toother target materials is available upon request.3.Consult Bently Nevada* Applications Note,Considerations when using Eddy Current ProximityProbes for Overspeed Protection Applications, whenconsidering this transducer system for tachometer or overspeed measurements.4.3300 XL 8 mm components are both electrically andphysically interchangeable with non-XL 3300 5 mmand 8 mm components. Although the packaging ofthe 3300 XL Proximitor Sensor differs from itspredecessor, its design fits in the same 4-holemounting pattern when used with the 4-holemounting base, and will fit within the same mounting space specifications (when minimum permissiblecable bend radius is observed).5.Mixing XL and non-XL 3300-series 5 mm and 8 mmsystem components limits system performance to the specifications for the non-XL 3300 5 mm and 8 mmTransducer System.6.The 3300-series 5 mm probe (refer to Specificationsand Ordering Information p/n 141605-01) usessmaller physical packaging, but does not reduce theside view clearances or tip-to-tip spacingrequirements as compared to an 8 mm probe. It isused when physical (not electrical) constraintspreclude the use of an 8 mm probe. When yourapplication requires narrow side view probes, use the 3300 NSv* Proximity Transducer System (refer toSpecifications and Ordering Information p/n 147385-01).7.8 mm probes provide a thicker encapsulation of theprobe coil in the molded PPS plastic probe tip. Thisresults in a more rugged probe. The larger diameterof the probe body also provides a stronger, morerobust case. We recommend that you use 8 mmprobes when possible to provide optimal robustnessagainst physical abuse.8.Each 3300 XL extension cable includes silicone tapethat you can use instead of connector protectors. We do not recommend silicone tape for applications that will expose the probe-to-extension cable connectionto turbine oil.Specifications and Ordering InformationSpecificationsUnless otherwise noted, the following specifications are for a 3300 XL 8 mm Proximitor Sensor, extension cable and 8 mm probe between +18 ︒C and +27 ︒C (+64 ︒F to +80 ︒F), with a -24 Vdc power supply, a 10 kΩ load, an AISI 4140 steel target, and a probe gapped at 1.27 mm (50 mils). Performance characteristics apply to systems that consist solely of 3300 XL 8 mm components. The system accuracy and interchangeability specifications do not apply to transducer systems that are calibrated to any target other than our AISI 4140 steel target.ElectricalProximitorSensor InputAccepts one non-contacting3300-series 5 mm, 3300 8 mm or3300 XL 8 mm Proximity Probeand Extension Cable.PowerRequires -17.5 Vdc to -26 Vdcwithout barriers at 12 mAmaximum consumption, -23 Vdcto -26 Vdc with barriers.Operation at a more positivevoltage than -23.5 Vdc can resultin reduced linear range.SupplySensitivityLess than 2 mV change in outputvoltage per volt change in inputvoltage.OutputResistance50 ΩNominal ProbeDC ResistanceResistance (R PROBE) from CenterConductor to Outer ConductorProbe Length R PROBE (Ω)0.5 7.45± 0.501.0 7.59 ± 0.501.5 7.73± 0.502.0 7.88 ± 0.503.0 8.17 ± 0.605.0 8.73± 0.709.0 9.87 ± 0.90 NominalExtension CableDC ResistanceResistance (R CORE) from CenterConductor to Center ConductorLength of ExtensionCable (m)R CORE (Ω)3.0 0.66± 0.103.5 0.77 ± 0.124.0 0.88± 0.134.5 0.99 ± 0.156.0 1.32± 0.217.0 1.54± 0.237.5 1.65 ± 0.258.0 1.76± 0.268.5 1.87 ± 0.28Resistance (R JACKET) from OuterConductor to Outer ConductorLength of ExtensionCable (m)R JACKET (Ω)3.0 0.20± 0.043.5 0.23 ± 0.054.0 0.26± 0.054.5 0.30 ± 0.066.0 0.39± 0.087.0 0.46± 0.097.5 0.49 ± 0.108.0 0.53± 0.118.5 0.56 ± 0.11Specifications and Ordering InformationExtension CableCapacitance69.9 pF/m (21.3 pF/ft) typical Field Wiring0.2 to 1.5 mm2(16 to 24 AWG) .Recommend using 3-conductorshielded triad cable and tinnedfield wiring.

DescriptionAccessories contribute to a reliable transducer system. Installing proximity probes during outages usually requiresone or more mounting accessories to help simplify the task.3300XL Transducer AccessoriesDatasheetBently Nevada Machinery Condition Monitoring145668Rev.HThese accessories allow you to quickly and efficiently install proximity probes and route the associated cables out of the machine case. These parts also help shield the cables from electrical noise and adverse environmental conditions. Having the proper mounting hardware on-site during the probe installation saves time and money for those responsible for the project.Junction boxesJunction boxes are normally mounted on or near the exterior of a machine case and enclose electrical connections in weatherproof or explosion-proof environments. Sealtite™ flexible conduit Flexible conduit routes probe cables safely to the sensor housing and then back to the monitors. The conduit protects transducer wiring from damage that splashing liquids or accidental contact with other equipment can cause.Sealtite flexible conduit consists of a galvanized steel core with an extruded thermoplastic cover. Pipe fittings are made of steel with a zinc-plated, chromate finish and are compatible with fittings found on our watertight equipment enclosuresProbe mounting bracketsProbe mounting brackets attach internally mounted proximity probes to the machine case. S upplied mounting bolts attach the bracket to the bearing or other location inside the machine casing. The bracket holds the probe and allows for adjustment of the probe tip relative to the observed surface.For most installations, use the standard 137492 non-clamping aluminum probe bracket. When using the 137491 brackets for 3/8-inch diameter smooth case probes, tightening the bolts will compress the probe hole around the probe and lock the probe into its preset gapped position. If your application requires additional electrical isolation from the mounting location (as in some generator and electric motor bearing locations), use the 27474 phenolic probe bracket. These mounting brackets are compatible with our 3300 and 3300 XL proximity probe systems, including 5 mm, 8 mm and NSv™ probes.To ensure that the brackets screws remain fastened within the machine, secure the screws with safety wire. Each mounting bracket includes special screws with holes drilled for safety wire.Cable SealThe optional 10076 Cable Seal is mainly for use in cable routing applications. It restrains the coaxial cable from movement, prevents abrasion, and provides splash protection. One end of the cable seal has a 1/4-18 NPT thread that allows you to thread it into a 4190-36 Adapter.The cable seal has an aluminum body and an oil-resistant, slit grommet so that you can install it over armored or non-armored cable without removing the connectors. AdapterThe optional 4190 Adapter attaches a junction box to the machine case. It also allows mounting of the proximity probe in some instances.The adapter offers a variety of threads and configurations. A dapter threads and configurations that are not listed in this data sheet may be available. P lease contact your sales representative for more information. Explosion-proof fittingsExplosion-proof fittings provide seals for housings in Division 1 and in Zone 0 and 1 hazardous areas. The fittings include sealing compound, packing fiber, and the appropriate adapter. Fitting kits are available. Refer to Explosion-Proof Fittings on page 6 for details and part numbers.Low-pressure cable sealThe 43501 Low-Pressure Cable Seal provides egress for up to 4 75Ω and/or 95Ω 3300XL, 3300 and 7200 cables, or up to 2 25mm DE or 50mmDE transducer cables, through a single hole in a machine case or other barrier.The cable seal is constructed of 303 stainless steel and a molded silicon rubber grommet and prevents leakage of fluids along the outer jacket of the cable. The seal has threads on both ends and fits into a tapped hole on the machine case or barrier. External pipe threads enable the seal to mate to conduit or housings. You can use the low-pressure cable seal only with non-armored cables. Its design seals pressures up to 345 kPa (50 psi) when properly installed.High-Temperature Cable TiesThe 173873 high-temperature cable tie is an economical alternative to metal brackets in high-temperature applications. These cable ties are molded from VICTREX® PEEK™ polymer for multiple uses in extreme environments up to +180°C (+356°F).SpecificationsJunction BoxesCylindrical Junction Box P/N 03818016 ComponentsMain body and blankcoverDimensionsOverall Height76 mm (3.0 in)Body Diameter89 mm (3.5 in)Hub-to-Hub121 mm (4.75 in) Base to Hub Center16 mm (0.64 in) Fittings3/4-14 NPT5 placesMaterial AluminumOptional Extension for 03818016 P/N 03818022ComponentsMain body Dimensions (Extensiononly)Overall Height93mm (3.7 in)Body Diameter90mm (3.6 in)Hub-to-Hub (flats)91 mm (3.6 in)Total ExtendedHeight150 mm (5.90 in) Material Aluminum Rectangular Junction Box P/N 03818065 ComponentsMain body and cover Dimensions Overall Height27.9 mm (1.10 in) Width of Body38.1 mm (1.50 in) Length of Body95.3 mm (3.75 in) Fittings1/2-14 NPT2 places Material Aluminum Rectangular Junction Box P/N 03818066 ComponentsMain body and cover Dimensions Overall Height61.0 mm (2.40 in) Width of Body44.5 mm (1.75 in) Length of Body102 mm (4.00 in) Fittings3/4-14 NPT2 places Material Aluminum Sealtite Flexible Conduit Components Refer to Figure 4.Fitting Options1/2-14 NPT3/4-14 NPTLength As ordered BracketsClamp Mounting Bracket for 3/8-inch diameter smooth body probesDimensions Refer to Figure 5.Mounting Screw Thread Size Options 10-24 UNC-2A M5 x 0.8-6gMaterial AluminumNon-Clamping Mounting Bracket for threaded case probesDimensions Refer to Figure 6.

Specifications and Ordering InformationPart Number 141194-01Rev. T (12/12)Bently Nevada* Asset Condition Monitoring 3300 XL 8mm Proximity Transducer SystemDescription The 3300 XL 8 mm Proximity Transducer System consists of: ∙ One 3300 XL 8 mm probe,∙ One 3300 XL extension cable 1, and ∙ One 3300 XL Proximitor * Sensor 2. The system provides an output voltage that is directly proportional to thedistance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor * reference and speed measurements 3.The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-metre system also fully complies with the American Petroleum Institute’s (API) 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual componentsEach 3300 XL 8 mm Transducer System component is backward-compatible and interchangeable 4 with other non-XL 3300 series 5 mm and 8 mm transducer system components 5. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space 6,7.Proximitor SensorThe 3300 XL Proximitor Sensor incorporates numerous improvements overprevious designs. Its physical packaging allows you to use it in high-density DIN-rail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older Proximitor Sensor designs. The mounting base for either option provideselectrical isolation and eliminates the need for separate isolator plates. The 3300 XL Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings, resulting in lower installation costs and complexity. The 3300 XL’s SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.Proximity Probe and Extension CableThe 3300 XL probe and extension cable also reflect improvements over previous designs. A patented TipLoc* molding method provides a more robust bond between the probe tip and the probe body. The probe’s cable incorporates a patented CableLoc* design that provides 330 N (75 lbf) pull strength to more securely attach the probe cable and probe tip. You can also order 3300 XL 8 mm probes and extension cables with an optional FluidLoc* cable option. This option prevents oil and other liquids from leaking out of the machine through the cable’s interior.ConnectorsThe 3300 XL probe, extension cable, and Proximitor sensor have corrosion-resistant, gold-plated ClickLoc* connectors. These connectors require only finger-tight torque (the connectors will "click" when tight), and the specially-engineered locking mechanism prevents the connectors from loosening. These connectors require no special tools for installation or removal.You can order the 3300 XL 8 mm probes and extension cables with connector protectors already installed. We can also supply connector protectors separately for field installations (such as when an application must run the cable through restrictive conduit). We recommend connector protectors for all installations to provide increased environmental protection8.Extended Temperature Range ApplicationsAn extended temperature range (ETR) probe and ETR extension cable are available for applications in which either the probe lead or extension cable may exceed the standard 177 ︒C (350 ︒F) temperature specification. The ETR probe has an extended temperature rating for up to 218 ︒C (425 ︒F). The ETR extension cable rating is up to 260 ︒C (500 ︒F). Both the ETR probe and cable are compatible with standard temperature probes and cables, for example, you can utilize an ETR probe with the 330130 extension cable. The ETR system uses the standard 3300 XL Proximitor Sensor. Note that when you use any ETR component as part of your system, the ETR component limits the system accuracy to the accuracy of the ETR system. Description Notes:1.1-metre systems do not use an extension cable.2.Proximitor sensors are supplied by default from thefactory calibrated to AISI 4140 steel. Calibration toother target materials is available upon request.3.Consult Bently Nevada* Applications Note,Considerations when using Eddy Current ProximityProbes for Overspeed Protection Applications, whenconsidering this transducer system for tachometer or overspeed measurements.4.3300 XL 8 mm components are both electrically andphysically interchangeable with non-XL 3300 5 mmand 8 mm components. Although the packaging ofthe 3300 XL Proximitor Sensor differs from itspredecessor, its design fits in the same 4-holemounting pattern when used with the 4-holemounting base, and will fit within the same mounting space specifications (when minimum permissiblecable bend radius is observed).5.Mixing XL and non-XL 3300-series 5 mm and 8 mmsystem components limits system performance to the specifications for the non-XL 3300 5 mm and 8 mmTransducer System.6.The 3300-series 5 mm probe (refer to Specificationsand Ordering Information p/n 141605-01) usessmaller physical packaging, but does not reduce theside view clearances or tip-to-tip spacingrequirements as compared to an 8 mm probe. It isused when physical (not electrical) constraintspreclude the use of an 8 mm probe. When yourapplication requires narrow side view probes, use the 3300 NSv* Proximity Transducer System (refer toSpecifications and Ordering Information p/n 147385-01).7.8 mm probes provide a thicker encapsulation of theprobe coil in the molded PPS plastic probe tip. Thisresults in a more rugged probe. The larger diameterof the probe body also provides a stronger, morerobust case. We recommend that you use 8 mmprobes when possible to provide optimal robustnessagainst physical abuse.8.Each 3300 XL extension cable includes silicone tapethat you can use instead of connector protectors. We do not recommend silicone tape for applications that will expose the probe-to-extension cable connectionto turbine oil.Specifications and Ordering InformationSpecificationsUnless otherwise noted, the following specifications are for a 3300 XL 8 mm Proximitor Sensor, extension cable and 8 mm probe between +18 ︒C and +27 ︒C (+64 ︒F to +80 ︒F), with a -24 Vdc power supply, a 10 kΩ load, an AISI 4140 steel target, and a probe gapped at 1.27 mm (50 mils). Performance characteristics apply to systems that consist solely of 3300 XL 8 mm components. The system accuracy and interchangeability specifications do not apply to transducer systems that are calibrated to any target other than our AISI 4140 steel target.ElectricalProximitorSensor InputAccepts one non-contacting3300-series 5 mm, 3300 8 mm or3300 XL 8 mm Proximity Probeand Extension Cable.PowerRequires -17.5 Vdc to -26 Vdcwithout barriers at 12 mAmaximum consumption, -23 Vdcto -26 Vdc with barriers.Operation at a more positivevoltage than -23.5 Vdc can resultin reduced linear range.SupplySensitivityLess than 2 mV change in outputvoltage per volt change in inputvoltage.OutputResistance50 ΩNominal ProbeDC ResistanceResistance (R PROBE) from CenterConductor to Outer ConductorProbe Length R PROBE (Ω)0.5 7.45± 0.501.0 7.59 ± 0.501.5 7.73± 0.502.0 7.88 ± 0.503.0 8.17 ± 0.605.0 8.73± 0.709.0 9.87 ± 0.90 NominalExtension CableDC ResistanceResistance (R CORE) from CenterConductor to Center ConductorLength of ExtensionCable (m)R CORE (Ω)3.0 0.66± 0.103.5 0.77 ± 0.124.0 0.88± 0.134.5 0.99 ± 0.156.0 1.32± 0.217.0 1.54± 0.237.5 1.65 ± 0.258.0 1.76± 0.268.5 1.87 ± 0.28Resistance (R JACKET) from OuterConductor to Outer ConductorLength of ExtensionCable (m)R JACKET (Ω)3.0 0.20± 0.043.5 0.23 ± 0.054.0 0.26± 0.054.5 0.30 ± 0.066.0 0.39± 0.087.0 0.46± 0.097.5 0.49 ± 0.108.0 0.53± 0.118.5 0.56 ± 0.11Specifications and Ordering InformationExtension CableCapacitance69.9 pF/m (21.3 pF/ft) typical Field Wiring0.2 to 1.5 mm2(16 to 24 AWG) .Recommend using 3-conductorshielded triad cable and tinnedfield wiring.
