本特利bently电涡流传感器工作原理

本特利bently电涡流传感器工作原理本特利bently电涡流传感器工作原理一、本特利bently电涡流传感器常用分类我们常接触到的本特利bently涡流传感器有直径5mm涡流传感器、8mm涡流传感器、11mm涡流传感器、14mm涡流传感器、25mm涡流传感器、50mm差胀传感器、3300耐高温电涡流传感器几种，其中5mm探头和14mm探头不常用。

每个传感器系统都由探头、延长线和前置器组成，本特利探头、延长线和前置器具有完全的可互换性，只要部件号一致，各部分可以互换。

二、本特利bently电涡流传感器工作原理电涡流传感器是以高频电涡流效应为原理的非接触式位移、振动传感器，其基本原理是探头、延伸电缆、前置器以及被测体构成基本工作系统。

前置器中高频振荡电流通过延伸电缆流入探头线圈，在探头头部的线圈中产生交变的磁场。

如果在这一交变磁场的有效范围内没有金属材料靠近，则这一磁场能量会全部损失；当有被测金属体靠近这一磁场，则在此金属表面产生感应电流，电磁学上称之为电涡流。

与此同时该电涡流场也产生一个方向与头部线圈方向相反的交变磁场，由于其反作用，使头部线圈高频电流的幅度和相位得到改变（线圈的有效阻抗），这一变化与金属体磁导率、电导率、线圈的几何形状、几何尺寸、电流频率以及头部线圈到金属导体表面的距离等参数有关。

通常假定金属导体材质均匀且性能是线性和各项同性，则线圈和金属导体系统的物理性质可由金属导体的电导率б、磁导率ξ、尺寸因子τ、头部体线圈与金属导体表面的距离D、电流强度I和频率ω参数来描述。

则线圈特征阻抗可用Z=F(τ, ξ, б, D, I, ω)函数来表示。

通常我们能做到控制τ, ξ, б, I, ω这几个参数在一定范围内不变，则线圈的特征阻抗Z就成为距离D的单值函数，虽然它整个函数是一非线性的，其函数特征为S型曲线，但可以选取它近似为线性的一段。

关于Bently位移探头安装及调试

首先要知道Bently探头的工作原理：第一，要给探头前置器提供-24V直流电压，前置放大器会把-24V直流信号转换成高频交流电流提供给探头；另一方面，前置放大器会感受由于探头和被测靶面距离变化而引起的探头线圈感抗的变化，经前置放大器处理产生与参数变化相对应的电压值作为输出。

下图为探头测量电压及前置放大器输出电压的过程：如上面两幅图所示，前置放大器会把探头测量到的电压调制成一个正玄波，波上的每一点表示探头当时测量到的电压值。

通过前置器内部的解调电路（原理是傅里叶级数）将测量到的电压分解成一个直流量和不同振幅的交流量，当被测量为位移时，取直流量，当被测量为振动时，取交流量的前几级分量。

第二，探头测量原理结合本厂位移探头调试说一下位移探头的调试方法：首先要明白串量的概念：串量既转动轴轴向串动的最大量，一般以“道”作为其单位。

（我厂串量为41道）调试方法有两种（大师讲解的）第一种：把轴打到远离探头一侧，打到最大串量（既41道），手拧位移探头直至拧不动，然后倒悬一个丝扣多一点（大约为1.2mm，一个丝扣为1mm）然后测量前置放大器输出电压，为9.75V时固定探头。

（1.2mm为经验值，因为探头的测量精度为7.87V/mm，1.2mm大致为9.75V，标准1.24mm，正好等于9.75V，有人会问为什么选择9.75V，而不选择其他电压值，这是有探头线性曲线决定的，9.75V正好处于探头线性曲线的中间部位，这样的话轴承串动时，可以保证测量电压都处于探头线性区域内，且的线性最好的区域）以本厂为例，报警值为0.56mm当轴串动到离探头最近时，电压值为：9.75+0.41*7.87=12.98V当轴继续向探头方向串动0.15mm时，将会报警，此时，巴氏合金已经磨损0.15mm.此时电压值为：9.75+0.41*7.87+0.15*7.87=14.16V当轴向远离探头方向串动0.56mm时报警，此时电压值为：9.75-0.41*7.87-0.15*7.87=5.34V此时巴氏合金已经磨损0.56mm。

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.

延伸电缆和探头的长度总和必须等于前置器上标明的总电气长度
4、振动、位移变送器
3500监测系统的组成
5、电涡流电感线圈产生的磁力线经过金属导体时，金属导体就会产生感应电流，且呈闭合回路，类似于水涡流形状，故称之为电涡流也叫做电涡流效应.
3500监测系统的组成
3500监测系统的作用
4、键相传感器电涡流传感器可以用来有效得提供基准相位信息。键相传感器的典型安装是将其探头呈放射状安装在转子周围，当转轴每次旋转时，就可以感知轴上设计特征信息（键槽等）。键相传感器可以创建一个基准信号用于测量绝对相位信息及确定机器的转速。前置器系统被安装好之后，将观测到大轴上的“凹槽”或“突出”的地方会比正常的振动或距离测量产生明显的电压变化。这种明显的差别使得3500监测系统将每转一周产生的有用的信号与背景的噪音信号或振动信号区分开来。键相位信号在机组故障诊断中非常有用。

2、延长导线（1）延长导线的结构：导体芯、内屏蔽层、外屏蔽层、绝缘层。 1）内屏蔽层和导体芯提供了顶部线圈到探头电缆微型连接器末端的连接。 2）外屏蔽层是没有连接到线圈或连接器，所以它不是系统的电气性能的一部分。这个外屏蔽层提供了内屏蔽层的机械保护。如果电缆的外层聚四氟乙烯涂层损坏，这可以防止不必要的线圈接地。内屏蔽接前置器COM端，如果在正常生产中外屏蔽遭到破坏建议及时更换。不同型号、类型接头塑封的颜色不同，如蓝色、紫色、灰色。（2）延长导线标签含义例如：330130-080-00-00 080 = 8.0米的总长度 00 =没有防护型外壳 00 =危险区域，不需认证 3300 XL电涡流传感器系统，可用扩展电缆长度为3.0，3.5， 4.0，4.5，7.5，8.0和8.5米。

bently位移传感器

概述3300 XL 11 mm电涡流传感器系统由以下几部分组成：·3300 XL 11mm探头·3300 XL 11mm延伸电缆·3300 XL 11mm前置器对于油膜轴承机器非接触式振动和位移测量，3300 XL 11mm 电涡流传感器系统可输出V/mm ( 100mV/mil )。

11mm的探头端部使这种传感器与我们标准的3300 XL8mm传感器系统相比具有更大的线性区。

它主要应用在要求大线性范围的下列测量：·轴向（推力）位移测量·蒸汽轮机的斜面差胀测量·往复式压缩机活塞杆位移或下降的测量·转速计和零转速测量·相位参考（键相位）信号3300 XL11mm前置器的设计目标是取代7200系列11mm和14mm传感器系统。

当从7200系统升级到3300 XL 11mm系统时，所有的部件都必须被3300 XL 11mm部件替换；同时，监测系统也要升级。

如果使用3500监测系统，则需要软件组态的升级版本，该版本可以兼容3300 XL 11mm系统；现存的3300监测系统也需要作相应的修改。

欲了解更多信息，可与本特利内华达公司当地的销售和服务代表联系。

应用建议：3300 XL11mm趋近式传感器系统设计用于频率范围从0到8kHz的位移或振动测量，典型应用包括径向振动和位移、轴向位移以及键相位测量。

应用注意事项：虽然前置器的终端和连接器具备静电释放保护功能，但在使用过程中还应对静电释放多加注意。

前置器3300 XL 11mm 前置器与3300 XL8mm前置器有同样的优点。

由于设计精巧，它既可以采用导轨安装，也可以采用传统的面板安装。

改进的抗辐射能力使它在安装上毋需作任何考虑就可以达到欧洲电磁兼容性标准，这一特性也可以使它免受附近各种高频无线电波的干扰。

前置器上的弹簧定位端子带使安装更方便快捷，不需要特殊的安装工具，连线也十分坚固可靠。

3500测振监测系统介绍监测系统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，我们的空压机和氧压机系统中都应用了BENTLY测振系统，因为超速对透平机组而言是极其危险的情形之一，所以必须安装超速保护系统。

本特利公司为此研制了由涡流传感器及超速保护监测器组成的电子超速监测系统，它是完整的超速保护系统的一部分。

我们的测振系统应用有3300和3500两种测振，这次重点介绍23500制氧机采用的3500测振系统3500监测系统是当今最新的机器检测系统，此系统能够通过多种传感器采集数据作为一个系统，提供连续、在线监测功能，适用于机械保护应用，它是本特利内华达采用传统框架形式的系统中功能最强、最灵活的系统，具有其他系统所不具备的多种性能和先进功能。

3500监测系统的设计目的如下●每个通道的价格比以往的监测系统更低，一表多用（轴振、偏心、轴位移、加速度可以通用），减少了工厂运作成本。

●数字化和集成化程度高，提高了监测系统的质量。

●支持在线插拔，维护时不需断电。

3500监测系统和我们以前使用的3300相比，3500比3300多了软件系统，而且一个软件多样化，且需要计算机进行组态，但组态完成以后就不再需要计算机。

而且也没有3300那样的显示面板，布置更密集。

BENTLY的3500监测保护系统由传感器（探头、延长电缆、前置器）就地电缆和监视器框架，计算机和软件组成。

我们就先从传感器开始介绍。

传感器1．1 传感器的组成及功能系统有三个独立的部分，其中任何单独一部分都不能称为传感器，这三部分分别是：探头，延伸电缆、前置器。

它既能进行静态（位移）测量,又能进行动态（振动）测量，主要用于油膜轴承机械的振动和位移测量，以及键相位和转速测量。

它能将一种物理量转化为另一种物理量，在前置器（也叫前置变送器）系统中，机械能被转化成电能，这个系统中使用的转换设备被称为前置器。

这种电子设备被安装在金属盒子里。

2.2.3选用与待校探头匹配合适的随机夹套，将夹套套在探头螺纹壳体上，适当调整夹套位置装入TK3-2校验仪的静态探头安装支架上，并确保待测探头保护罩（探头前端非金属部分）全部露出金属支架孔，并用支架上的紧固螺钉固定紧探头壳体。

2.2.4 调节百分螺杆，使试件盘贴紧探头保护罩端面，记录此时百分螺杆刻度上的示值S(为校验方便可直接把示值调到零位置)慢慢移动百分螺杆，使试件盘远离探头端面，观察并记录校验仪（1045）显示的“位移电压（V）”，使电压值为-2.00V，此时百分螺杆刻度值为S1。

（S1-S=△S1，△S1为传感器的非线性区或最小安装间隙）2.2.5根据检测传感器的量程，可将传感器的满量程线性区等分成十个点，以便等间距改变探头端面和试件盘的间隙，传感器输出的等间距电压值通过校验仪（1045）直接读数。

可根据测试数据计算传感器的灵敏度、灵敏度偏差、非线性误差。

电涡流传感器的输出特性可用位移-电压曲线表示，如下图所示。

其中，图示的横坐标表示位移的变化，纵坐标代表前置器输出电压的变化。

理想位移-电压曲线是斜率恒定直线，直线的a-c段为线性区，即有效测量段。

b点为传感器线性中点。

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.

本特利振动探头原理

本特利振动探头原理引言：本特利振动探头是一种常用的实验仪器，用于研究物体的振动特性。

它基于本特利原理，通过测量物体的振动频率和振动幅度，可以得到物体的振动特性参数。

本文将详细介绍本特利振动探头的原理和工作方式。

一、本特利原理本特利原理是指当一个物体在振动时，会产生特定频率的声音。

这是因为振动会引起周围空气的压力变化，从而产生声波。

根据本特利原理，我们可以通过测量声波的频率和振幅来了解物体的振动情况。

二、本特利振动探头的结构本特利振动探头由振动传感器和信号处理器组成。

振动传感器通常采用压电陶瓷材料，它可以将物体的振动转化为电信号。

信号处理器则负责对传感器采集到的信号进行放大、滤波和数字化处理。

三、本特利振动探头的工作原理当本特利振动探头靠近一个振动的物体时，振动传感器会受到物体的振动力的作用，产生相应的电信号。

这个电信号经过放大、滤波和数字化处理后，转化为振动的频率和振幅信息。

四、本特利振动探头的应用本特利振动探头广泛应用于机械工程、材料科学和生物医学等领域。

例如，在机械工程中，可以利用本特利振动探头来分析机械设备的振动状况，从而判断设备是否存在故障或磨损。

在材料科学中，可以使用本特利振动探头来研究材料的振动特性，评估材料的质量和性能。

在生物医学中，本特利振动探头可以用来检测人体的生理信号，如心跳和呼吸等。

五、本特利振动探头的优势和局限性本特利振动探头具有以下优势：1. 非接触式测量：本特利振动探头可以远距离测量物体的振动，无需接触被测物体，避免了对物体的干扰。

2. 高灵敏度：本特利振动探头可以测量微小振动，具有较高的灵敏度。

本特利探头的安装调试

本特利探头的安装调试摘要：简明的介绍了大型转动设备轴系监测的3500系统的原理，详细说明了其在实际应用中的注意事项及调试方法。

关键词：电涡流传感器轴系监测安装调试概述：当今化工领域，工艺过程的长周期运行依赖于大型旋转设备不停息的运转，其一旦发生故障不仅影响生产效益，更有可能造成灾难性后果。

为确保这些大型旋转设备安全平稳运行，必须对其状态进行实时监测，本特利3500系统是监测其运行参数的有效工具，而探头的安装质量直接影响其长周期运行，是其最基本也最关键一环。

1基本原理：本特利3500系统由电涡流传感器探头、延伸电缆、前置器所组成的传感器系统以及3500检测模块组成。

探头安装于现场，检测轴承的振动、位移、转速等；延伸电缆用来连接探头与前置器，传输探头检测到的信号；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检测模块接收的电压信号。

至此，电涡流传感器系统，将被测轴承表面与探头顶端的距离转变为容易采集识别的直流或者交流电压信号分别用以分析轴承的位移或者震动。

2探头的安装探头安装之前务必确保所用探头选型正确且检验合格，探头的线性范围与其探头直径有着确定的关系，且探头直径越大其线性范围越宽，所以根据设备的极限动距离即可选定探头直径。

为了直观简洁，下面均已8mm系统为例说明。

8mm 探头的线性范围约从0.25到 2.3mm处对应电压-1到-17vdc，对应关系为7.87v/mm。

根据现场安装条件选定合适的延伸电缆长度以及与之匹配的前置器型号，现场安装时切记混搭以免影响传感器系统线性造成测量失真。

2.1探头安装应注意以下问题：①安装面的大小以及探头与安装面之间的距离；②安装支架的选择；③探头与探头之间的距离；④探头锥孔的清洁以及安装间隙的确定；⑤探头电缆外观检查以及走线固定；⑥探头转接头的密封与绝缘。

其中①②③应有设备供应商完成，且在设备第一次空负荷试车时检验，仪表工作人员通常只需做好④⑤⑥。

在探头安装前应检查探头外观是否完好，线缆有无破损，探头阻值是否在正常范围内，如无异常则可以安装调试。

本特利振动探头原理

本特利振动探头原理
本特利振动探头（Bendix test head）是一种用于检测材料的机械性质的探头。

它基于本特利振动原理，通过测量材料在振动状态下的谐振频率来得出材料的一些力学性质。

本特利振动原理是指当一个材料通过振动时，其频率与材料的力学性质有关。

在本特利振动探头中，探头的一端连接到被测材料上，当探头振动时，被测材料也会产生相应的振动。

探头的另一端连接到一个压电传感器上，该传感器可以测量探头的振动频率。

在测量过程中，探头会通过一个外部的激励源进行振动，激励源可以是机械力或电动力。

当探头振动时，通过压电传感器可以测量到探头的谐振频率。

根据本特利振动原理，该谐振频率与被测材料的力学性质，如弹性模量、剪切模量和压缩模量等有关。

测量过程中，通常需要根据被测材料的几何形状和尺寸进行修正计算，以获得准确的力学性质值。

此外，还可以通过测量材料的谐振频率随温度变化的特性，来研究材料的热膨胀性质。

总的来说，本特利振动探头通过测量振动频率来得出材料的力学性质，是一种常用的非破坏性材料测试方法。

它在工业生产和科学研究中具有广泛的应用，可以用于材料的质量检测、材料的设计与开发等。
