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.

3300bently系统安装时应注意接地问题
监测保护系统现场安装时应注意的几个接地问题刘道霖美国本特利内华达公司北京办事处方案策划工程师关键词：传感器、监测保护系统、屏蔽、公共端、接地随着电子和计算机技术的飞跃发展，工业自动化仪表已从原有的单元仪表向组合仪表发展，仪表系统已普遍使用大规模集成电路、超大规模集成电路、微处理器等电子器件。
各系统之间的连接方式也从以前的硬接线向计算机化的接口形式发展。
由于绝大部分工业自动化仪表系统所处理的信号为弱电信号，而弱电信号很容易受到干扰信号的影响而导致系统误报警和误动作，这就要求工业自动化仪表系统具有良好的抗干扰能力。
而从现场实际使用中反馈的信息告诉我们，系统没有正确的连接（接线）是引入干扰的一个主要原因之一。
本文作者走访了一些用户，从现场了解到的情况看，确实存在一些问题。
本文就本特利内华达公司所生产的3300系列和3500系列监测保护系统在现场安装时应注意的几个接线问题，提醒有关设计部门和使用者，检查您们的设计和现场接线是否正确。
如确实存在接线问题，希望能够尽快解决。
使监测保护系统能够更加安全、可靠、稳定地工作，让它成为可信赖的系统，使企业从这一系统中得到超值的回报。
本特利内华达公司所生产的监测保护系统主要应用在大型旋转和往复式机械的本体振动等监测保护方面，它由传感器、延长电缆、前置器、就地电缆和监测保护系统组成。
这一系统的具体接线要求如下：传感器系统：传感器（探头）一般安装在机组上。
对于涡流传感器，它通过延长电缆与前置器相连。
要求探头电缆与延长电缆及延长电缆与前置器的连接要正确可靠，探头电缆与延长电缆的连接接头应用专用的接头保护器或热缩管、绝缘胶带包好。
严禁将接头裸露，因裸露的接头一旦与轴承箱或台板接触，会带来严重的干扰和测量误差，甚至系统无法正常工作。
就地电缆：前置器通过就地电缆与监测保护系统相连接。
就地电缆应选用带屏蔽层的三芯电缆（对于速度传感器可选用两芯屏蔽电缆），单根的截面积大于等于0.5平方毫米。

3300 5mm TransducerSpecifications and Ordering InformationPart Number 172036Rev. F (05/08)DescriptionTransducer SystemThe 3300 5mm Proximity Transducer System consists of:• a 3300 5 mm probe 1, 2• a 3300 XL extension cable (ref 141194-01) •a 3300 Proximitor ® Sensor 3, 4, 5 (ref 141194-01)When combined with a 3300 XL Proximitor Sensor and XL extension cable, the system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. The system can measure both static (position) and dynamic (vibration) data. Its primary use is in vibration and position measurement applications on fluid-film bearing machines, as well as Keyphasor ® measurement and speed measurement applications 6. The system provides an accurate, stable signal output over a wide temperature range. All 3300 XL Proximity Transducer Systems achieve this level ofperformance with complete interchangeability of probe, extension cable, and Proximitor sensor, eliminating the need for individual component matching or bench calibration. Proximity ProbeThe 3300 5 mm probe improves upon previous designs. A patented TipLoc™ molding method provides a more robust bond between the probe tip and the probe body. ConnectorsThe 3300 5mm probe and 3300 XL extension cable have corrosion-resistant, gold-plated brass ClickLoc™ connectors. These connectors require only finger-tight torque (connectors will "click"), and the specially engineered lockingmechanism prevents the connectors from loosening. The connectors require no special tools for installation or removal.You can order 3300 5mm Probes and XL Extension Cables with connector protectors already installed, or we can supply the connector protectors separately for installation in the field (such as when you must run the cable through restrictive conduit). We recommend connector protectors for all installations to provide increased environmental protection 7.Specifications and Ordering InformationPart Number 172036Rev. F (05/08)Notes:1.A 5mm probe uses smaller physical packaging and provides the same linear range as a 3300 XL 8mm probe (ref 141194-01). The 5mm probe does not, however, reduce thesideview clearances or tip-to-tip spacing requirements as compared to an XL 8 mm probe. IYou should use the 5mm probe when physical (not electrical) constraints preclude the use of an 8mm probe, such as mounting between thrust bearing pads or other constrained spaces. When your application requires narrow sideview probes, use the 3300 XL NSv™ probe and extension cable with the 3300 XL NSv Proximitor Sensor (refer to Specifications and Ordering Information p/n 147385-01).2.XL 8 mm probes provide a thicker encapsulation of the probe coil in the molded PPSplastic probe tip to produce a more rugged probe. The larger diameter of the probe body also provides a stronger, more robust case. We recommend the use of XL 8mm probes when possible to provide optimal robustness against physical abuse.3.A 3300 XL Proximitor Sensor is available and provides many improvements over the non-XL version. The XL sensor is electrically and mechanically interchangeable with the non-XL version. Although the packaging of the 3300 XL Proximitor Sensor differs from its predecessor, its design allows you to usea 4-hole mounting base to fit it t in the same 4-hole mounting pattern and to fit within the same mounting space specifications (when the application observes the minimum permissible cable bend radius). Consult Specifications and Ordering Information (p/n 141194-01) or our sales and service professional for more information.4. Us of XL components with 3300 5mm Probes will limit system performance to the specifications for the non-XL 3300 system.5. The factory supplies Proximitor Sensors that are calibrated by default to AISI 4140 steel. Calibration to other target materials is available upon request.6.If you are considering using this transducer system for tachometer or over-speedmeasurements, consult /bently for the application note regarding the use of eddy current proximity probes for over speed protection.7. We provide silicone tape i with each 3300 XL extension cable. You can use this tape instead of connector protectors. We do not recommend silicone tape in applications which will expose the probe-to-extension cable connection to turbine oil.SpecificationsUnless otherwise noted, the following specifications are for a proximity transducer system 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).

Specifications and Ordering InformationPart Number 141623-01Rev. C (08/07)Bently Nevada™ Asset Condition Monitoring3300 High Temperature Proximity SystemDescriptionGas and steam turbines can produce temperatures hot enough to damage or destroy conventional proximity probes. The 3300 High Temperature Proximity System (HTPS) is designed to withstand the extreme temperatures found inside gas turbines, steam turbines and other types of rotating machinery. The HTPS measures vibration, thrust position, differential expansion and other parameters inside the hot areas of these machines. High temperature installations include:• Near a labyrinth seal in steam turbines • Differential expansion in steam turbines• When probe cables are routed through struts that support the bearing housing of a gas turbine• When probe cables are routed out through the exhaust path of a gas turbine• Monitoring a troublesome bearing in a high temperature area • Mode shape analysis at the mid-span location on steam and gas turbines for online machinery diagnostics• Interstage radial and axial seal clearance measurements at the mid-span location of multi-stage steam turbines to minimize seal rubs •Most hot bearing locations that can destroy conventional proximity probesHigh temperature transducer with a rugged designThe 3300 High Temperature Proximity System can be used for proximitymeasurements at hot locations with excellent results. Customer benefits include:• Proximity probe with integral hardline cable rated for +350°C (+662°F) continuous service in extreme conditions• 4 mm (160 mils) of linear range for most measurements in the hot sections of the machine• Hermetically-sealed ceramic probe tip seals out moisture and contaminants for added durability• Ceramic tip and stainless steel construction resists heat, moisture and corrosion• Threaded and smooth case styles for various types of probe mounting • Hardline cable available in lengths of 1, 2 and 5 metres for routing cable through hot sections of the machine•3.94 V/mm (100 mV/mil) signal output compatible with virtually all new and existing Bently Nevada monitors and diagnostic equipmentMode shape analysisThe 3300 High Temperature Proximity System is used to protect and manage critical machines in your facility for increased safety and efficiency. It is also used for mode shape analysis when measurements are taken at the turbine mid-span location. Mode shape analysis is important for research and development of a new steam or gas turbine design or when troubleshooting an existing design. Mode identification probes provide lateral mode shape information which is extremely valuable for balancing rotating machinery and identifying faults such as shaft cracks, bearing failures, rotor-to-stator rubs and other machine problems.For test and measurement applications, the HTPS will meet or exceed most requirements for making proximity measurements in high temperature environments. It is a viable option for your most challenging test problems.The Bently Nevada 3300 High Temperature Proximity System is an advanced transducer designed for making proximity measurements at hot bearing locations in your machine. This transducer delivers dependable service in severe environments and is an ideal solution when using proximity probes at elevated temperatures.Because of its thick hardline cable, the HTPS probe can be difficult to gap using a traditional threaded probe and bracket. Therefore, we recommend using smooth case probes, particularly if ordering a longer (2-metre or 5-metre) probe. The smooth case probes come with a clamp style mounting bracket to allow the probe to be gapped without turning.Specifications and Ordering InformationSpecificationsUnless otherwise noted, the following specifications are for a a 3300 16 mm HTPS Proximitor® Sensor, matched extension cable and probe at 22 +4.4°C (72 +8°F), with a -24 Vdc power supply, a 10 kΩ load, a Bently Nevada supplied AISI 4140 steel target that is 31 mm (1.2 in) diameter or larger, and a probe gap of 2.5 mm (100 mils). The system accuracy and interchangeability specifications do not apply when using a transducer system calibrated to any target other than a Bently Nevada AISI 4140 steel target. ElectricalProximitorSensor InputAccepts one noncontacting 3300HTPS 16 mm Proximity Probe withmatched Extension Cable.PowerRequires -19.6 Vdc to -26 Vdc at12 mA maximum consumption.Operation at a more positive volt-age than -23.5 Vdc can result inreduced linear range.SupplySensitivityLess than 13 mV change in outputvoltage per volt change in inputvoltage.Outputresistance50 ΩProbe dcresistance:Probe Length (m) Resistance from the CenterConductor to the OuterConductor (RpROBE) (°hms)1.0 5.062.0 5.825.0 8.11 Extension cabledc resistance:Length ofExtension Cable(m)Resistance fromCenterConductorto CenterConductor(R CORE) (ohms)Resistance fromCoaxialConductor toCoaxialConductor(R JACKET)(ohms)4.0 0.88 0.267.0 1.62 0.498.0 1.84 0.55 Extension cablecapacitance:69.9 pF/m (21.3 pF/ft) typicalField wiring:Maximum length of 305 metres(1,000 feet) between the 3300HTPS Proximitor Sensor and themonitor.

Care should be taken tomaintain minimum separation oftransducer tips, generally at least64 mm (2.5 in) for dual axialposition measurements or 54 mm(2.1 in) for radial vibrationmeasurements to prevent crosstalk. Radial vibration or positionmeasurements on shaftdiameters smaller than 152 mm(6.0 in) will generally result in achange in scale factor due to thecurvature of the shaft surface.Consult PerformanceSpecification 159132 foradditional information.

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.

大温度范围应用
当探头引线或延伸电缆在应用中可能超过 177ºC（350ºF）时，可以采用大温度范围 （ETR）探头和延伸电缆。大温度范围探头的 探头引线和接头的温度范围可达 260ºC （500ºF）。ETR 探头和延伸电缆与标准温度 范围的探头和电缆兼容。例如，可以将 ETR 探头和 330130 延伸电缆一起使用。
技术规格
在没有另外注明时，以下关于 3300 XL8 mm 前置器、延伸电缆和探头的技术规格是在下 列条件下得到的：温度+18°C～+27°C （+64°F～+80°F°），－24Vdc 电源供电， 10KΩ负载，AISI4140 钢被测靶面，探头间隙 为 1.27mm (50mils)。 技术特性适用于完全 由 3300 XL 8mm 部件组成的系统。其精度和 可互换性指标不适用于未经本特利内华达 AISI 4140 钢靶面校准的传感器系统。
机组仪表-本特利探头(传感器的静态校验)
（3）将-24VDC送到前置放大器的电源端和公共端，调节TK3-2E校验仪上的螺 旋千分尺，使示值对准0 mm处，然后将千分尺的示值增加到0.25 mm，记录 数字电压表的电压值(此值为前置器输出电压)。以每次0.25 mm的数值增加间 隙，直到示值为2.5mm为止，并记录每一次的输出电压值。(校验点不少于10 点)。
前置器检测电路检测探头线圈的感抗变化。再经放大电路 将感抗变化量变换放大成相应电压变化信号输出。经监测 仪进行信号转换并显示,转换成4~20mA,1~5V的标准信号送 入DCS或PLC中，在测量中，前置器放大输出的直流电压信 号用做机械位移的测量，交流电压信号用做振动的测量。
机械转速主要是测转子的齿轮或孔眼，经过传感器产生脉 冲或方波，并通过频率信号输出。在现场实际应用的传感 器原理不同。一般有电涡流传感器、磁电式传感器、光电 式传感器等
二、工作原理 机器的振动、位移总是伴随着机器的运转，即使是机器在
最佳的运动状态，由于很微小的缺陷，也将产生某些振动 。在工作中我们常用的振动位移监测仪是由电涡流传感器 、前置器、延伸电缆、监测仪转换器组成，其构成原理如 图所示。探头线圈监测仪
探头线圈接受前置器振荡电路来的高频电流，在其周围产 生高频磁场，该磁场穿过靠近它的转轴金属表面，在其中 产生一个电涡流，该电涡流产生的磁场方向和线圈磁场方 向相反，改变了原线圈的感抗，该感抗的变化随探头顶部 金属表面的间隙变化而变化。
（2）延伸电缆完整、无短路、无开路、接头无氧化锈蚀 ，保护层无破损。
（3）前置器完整无损，安装盒无脱漆、变形和密封不良 现象，前置器与安装盒之间需有良好的绝缘层。
（4）信号电缆屏蔽层接地良好，用500V兆欧表检查信号 线间及对地绝缘电阻应大于5 MΩ。并要求单点接地。

1 本特利监测系统结构1.1 本特利电涡流传感器的构成电涡流传感器系统由三个部分组成，分别是传感器探头、延伸电缆、前置放大器。
传感器探头内部含有一个线圈，探头的端部由聚苯撑硫（PPS）材料组成，线圈被厚实的封装到探头的端部，探头壳体材料为不锈钢，线圈与75 欧姆宽带同轴电缆相连，同轴电缆中心是导体芯，有中心向外展开依次为绝缘层、内屏蔽层、外屏蔽层（网状屏蔽层）和外护套，内屏蔽层和线圈相连，外屏蔽层不和线圈相连，延伸电缆同样为同轴电缆，两端的接头分别与探头和前置放大器相连接。
前置器是一种内部装有振荡电路和调制解调器测量电路的密闭金属盒，接收电涡流传感器和延伸电缆的信号，需要给前置器的电压VT 端和公共端COM 端输入-17.5VDC耀-26VDC 的驱动电压。
前置器的VOUT 端为输出端。
传感器系统的结构构成图如图1 所示。
1.2 本特利监测系统结构组成监测系统由电涡流传感器系统，3500 监测模块组成，其中前置器接收由探头和延伸电缆传输的信号，并将其转换为3500 监测模块接收的电压信号，通过内部逻辑运算，向各保护装置（DCS 和SIS）送出模拟量和数字量信号。
