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.

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.

本特利电涡流传感器工作原理、安装及常见故障总结处理

引言在笔者所在单位大空分空气透平压缩机、天然气转化制甲醇合成气压缩机，低密度聚乙烯循环气压缩机等大型旋转机械上都使用本特利电涡流传感器来测量压缩机的轴的位移、振动及转速等，本文说明了电涡流传感器的构成及工作原理，介绍其在大型旋转机械设备监测中的应用、安装方法并总结常见故障。

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 ~-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。

图1传感器系统的结构构成图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。

3500系统模块组件如图2所示。

1.3电涡流传感器工作原理电涡流传感器是一种相对式非接触传感器，前置器的振荡电路产生的高频振荡电流流入探头内部线圈，线圈中便会产生交变的磁场，当被测金属转轴靠近这一交变磁场，就会在转轴表面产生感应电流，同时，该感应电流也产生一方向与探头内部线圈方向相反的交变磁场，两个磁场相叠加，将改变线圈的阻抗。

该线圈阻抗可近似看成是探头顶部到金属表面间隙的单值函数，即两者之间成正比例关系。

3300XL5mm 8mm探头调试要求

本特利探头调试要求本工程选用的是本特利3300XL系列探头、延长电缆、前置器（5米系统），它的灵敏度为7.87V/mm,关于探头、延长电缆、前置器的说明见附件。

1.当探头用于测量轴振动时：调试要求：探头与被测轴之间的间隙值为1.27mm (50mil)，转换成电压值为-9.75Vdc。

调试过程：将探头、延长电缆和前置放大器连接好后，用万用表测量前置放大器的COM和OUT两个端子之间的电压，通过旋入/出探头将电压调整为-9.75Vdc即调整完毕。

2.当探头用于测量键相时：调试要求：探头与被测轴之间的间隙值为1.27mm (50mil)，转换成电压值为-9.75Vdc。

调试过程：将探头、延长电缆和前置放大器连接好后，用万用表测量前置放大器的COM和OUT两个端子之间的电压，通过旋入/出探头将电压调整为-9.75Vdc即调整完毕。

3.当探头用于测量位移时：调试要求：探头与被测轴之间的间隙值为1.27mm (50mil)，转换成电压值为-9.75Vdc。

调试过程：把轴打到轴窜量的中间位置，将探头、延长电缆和前置放大器连接好后，用万用表测量前置放大器的COM和OUT两个端子之间的电压，通过旋入/出探头将电压调整为-9.75Vdc即调整完毕，此时在控制室应显示位移值为0，误差不超过0.02mm。

注意事项：●调试时要先试一下探头安装位置的螺纹是否很轻松的旋入，如果旋入不畅，用对应的丝锥重新攻丝。

●调试时要用8/10的开口搬手和4”活搬手，不能使用过大的搬手，防止将探头拧断。

●调试键相时探头不能正对着键相凹槽，要远离键相凹槽。

●调试过程中要一直将万用表接入，保证一直能监测到间隙电压，间隙电压的变化趋势为-24VDC～0 VDC。

●调试位移时要保证转子在整个轴向间隙的中间位置，否则调试出的结果会有很大的误差。

●调试位移时要确认3500系统中组态的中性点电压为-9.75VDC。

●本特利的3300XL探头、延长电缆、前置器不同型号之间可以互换。

3300 XL8mm 系统是我们性能最先进的电涡流传感器系统，100%符合美国石油学会（API）为这类传感器制定的 670 标准（第四版）。所有的 3300 XL 8mm 电涡流传感器系统都能达到规定的性能标准，并且探头、延伸电缆和前置器具有完全可互换性，不需要单独的匹配组件或工作台校准。
3300 XL 8mm 传感器系统的每一个组件都是向后兼容的，并且和其它的非 XL 3300 系列的 5mm 和 8mm 传感器系统组件 3 可互换 4。例如，当没有足够的空间安装 8mm 探头时，通常使用 3300 5mm 探头来代替。 5，6
3300 XL 8mm 探头和延伸电缆在订货时可选择已安装接头保护器，也可以选择在现场安装（如电缆必须布放在约束导管中）。潮湿环境中为接头，推荐在所有的安装中都选用接头保护器，提供环境保护 7。
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)

（2）用合适的探头夹把探头固定在探头座上，使探头顶端部接触到校验靶片。
（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。
