festo电容式接近传感器

festo电容式接近传感器德国FESTO费斯托电容式接近传感器的原理festo电容式接近传感器由高频振荡器和放大器等组成，由传感器的检测面与大地间构成一个电容器，参与振荡回路工作，起始处于振荡状态。当物体接近传感器检测面对，回路的电容量发生变化，使高频振荡器振荡。振荡与停振这二种状态转换为电信号经放大器转化成二进制的开关信号。电容式接近传感器的原理所有金属型传感器基本上属于高频振荡型。和普通型一样，它也有一个振荡电路，电路中因感应电流在目标物内流动引起的能量损失影响到振荡频率。目标物接近传感器时，不论目标物金属种类如何，振荡频率都会提高。传感器检测到这个变化并输出检测信号。电感式接近开关的基本工作原理电感式传感器为信号发生器，它被用于在加工机械，机器人，生产线以及传送带系统中检测和功能相关的动作,并将检测结果转换成电信号。它是以非接触的方式工作的。当有金属物体接近规定的感应距离时，传感器会发出一个电信号。电感式接近开关就是利用电涡流效应制造的传感器。（1）高频振荡型电感式接近开关：它以高频振荡器（LC振荡器）中的电感线圈作为检测元件，利用被测金属物体接近电感线圈时产生的涡流效应，引起振荡器振幅或频率的变化，由传感器的信号调理电路将该变化转换成开关量输出，从而达到检测的目的。（2）差动线圈型电感式接近开关：它有两个电感线圈，由其中一个电感线圈作为检测线圈，另一个电感线圈作为比较线圈；由于被测金属物体接近检测线圈时会产生涡流效应，从而引起检测线圈中磁通的变化，检测线圈的磁通与比较线圈的磁通进行比较，然后利用比较后的磁通差，经由传感器的信号调理电路将该磁通差转换成电的开关量输出，从而达到检测的目的。2.3.2电感式接近开关的分类（1）按工作电源的性质进行分类①流型：采用交流电源供电，用于交流控制回路。②流型：采用直流流电源供电，用于直流控制回路。（2）按接线方式进行分类①二线制②三线制③四线制④五线制⑤六线制（3）按触点的性质分类①常开式②常闭式③常开与常闭混合式festo电容式接近传感器按输出逻辑分类①正逻辑型②负逻辑型③浮空逻辑型④混合型（5）按外形分类①螺纹型②圆柱型③长方体型④U型等（6）按防护方式分类①防水型②防爆型③耐高温型④耐高压型等2.3.3电感式接近开关的图形符号接近开关通用符号如图2.2所示，电感式接近开关如图2.3所示。图2.2接近开关通用符号图2.3电感式接按开关图形符号2.3.4电感式传感器的特点-无机械磨损和撕扯动作，因此使用寿命长；-不会因灰尘或触点焊接在一起而出现故障；-无触点反弹，因此无切换故障；-切换频率高达3000Hz；-抗震；-安装位置随意；-黄色LED显示切换状态；-完全密闭，防护等级高。2.3.5电感式传感器在自动检测中的应用由于电感式传感只能对金属起作用，在自动控制的应用可以应用在上例中进行检测白色的金属或红色的塑料，又可以应用在流水生产线上检测金属工件是否到位。如图2.4所示。当工件到位后自动输出一个开关量信号。用以控制计数器计数或下一个加工步骤等。festo电容式接近传感器[详细]

倍加福电容式传感器

检测距离的衰减性。滑翘为铁质，适合电感式传感器检测；而滑翘被测部分的尺寸略小于标准检测物尺寸（标准被测物尺寸为3倍额定检测距离，此应用中，标准尺寸应为120*120mm），这样的话就会有一定的衰减。现场抗干扰能力。这个是不容忽视的问题，普通电感式传感器容易被电机或变频器干扰，很多技术人员只对在此附近的应用选择相应强抗电磁干扰的传感器。但在汽车制造车间，厂房大，现场技术人员习惯使用对讲机沟通，尤其是边走边用对讲机对话时，会不经意的靠近传感器，导致短暂失效。安装方面。随着电感式传感器的普及，传感器不仅仅在电气性能方面有所提升，其机械方面的设计也越来越人性化。要在Z*程度的实现人性化安装。减少了多种近似产品的备货和减少了安装、维护的时间。稳定运行的保障。在车厂的使用中，要杜绝任何油污、尘污的侵蚀。另外，滑翘经过轨道时，震动是长期存在的，优异的抗震动性同样是有着非常重要的作用。电感式传感器具有以下特点：结构简单，传感器无活动电触点，因此工作可靠寿命长。灵敏度和分辨力高，能测出0.01微米的位移变化。传感器的输出信号强，电压灵敏度一般每毫米的位移可达数百毫伏的输出。线性度和重复性都比较好，在一定位移范围（几十微米至数毫米）内，传感器非线性误差可达0.05%~0.1%。同时，这种传感器能实现信息的远距离传输、记录、显示和控制，它在工业自动控制系统中广泛被采用。但不足的是，它有频率响应较低，不宜快速动态测控等缺点。电感式传感器种类很多，常见的有自感式，互感式和涡流式三种。另外，更深入的讲，在抗电磁干扰性、环境温度、电压扰动以及安装要求等方面，都存在着差异。安装方面。随着电感式传感器的普及，传感器不仅仅在电气性能方面有所提升，其机械方面的设计也越来越人性化。要在Z*程度的实现人性化安装。减少了多种近似产品的备货和减少了安装、维护的时间。稳定运行的保障。在车厂的使用中，要杜绝任何油污、尘污的侵蚀。另外，滑翘经过轨道时，震动是长期存在的，优异的抗震动性同样是有着非常重要的作用。对于电感式传感器，大家都不会陌生，是用于近距离定位金属物体的通用方式。因为主要是通过霍尔效应来完成检测，所以也称为霍尔传感器。其内部结构由两部分构成：前端由缠绕着发射、接收线圈的铁芯构成检测部分；后端为电路部分，整体封装在塑料或金属外壳中。工作时，电磁铁芯部分发生交变磁场，对靠近的金属物体表面产生涡流效应，从而削弱LC震荡电路，放大电路部分分析电磁铁芯接收线圈的微弱LC震荡电路变化，并给予相应的输出。不同外形尺寸，其额定检测距离一般至多到100mm。通常状态下，各厂家对于其标称的检测距离为在实验室条件下测得的额定检测距离。实际应用中，考虑到各方面的环境因素，其可靠检测距离约为额定检测距离的80%，但对于被测物是有一定要求的。由于应用现场的被测物材料的导磁性和尺寸大小，一般情况下达不到标准被测物的要求，那么传感器的检测距离会进一步的衰减，这也就是很多用户感觉电感传感器的检测距离比厂家标称的小很多的原因。在这种非标检测的情况下，各厂家及其不同系列产品的差异较大。把被测的机械量，如位移、压力等转换为电容量变化的传感器。它的敏感部分就是具有可变参数的电容器。其Z常用的形式是由两个平行电极组成、极间以空气为介质的电容器。若忽略边缘效应，平板电容器的电容为εS/d，式中ε为极间介质的介电常数，S为两极板互相覆盖的有效面积，d为两电极之间的距离。d、s、ε三个参数中任一个的变化都将引起电容量变化，并可用于测量。因此电容式传感器可分为极距变化型、面积变化型、介质变化型三类。极距变化型一般用来测量微小的线位移或由于力、压力、振动等引起的极距变化(见电容式压力传感器)。面积变化型一般用于测量角位移或较大的线位移。介质变化型常用于物位测量和各种介质的温度、密度、湿度的测定。70年代末以来，随着集成电路技术的发展,出现了与微型测量仪表封装在一起的电容式传感器。这种新型的传感器能使分布电容的影响大为减小，使其固有的缺点得到克服。电容式传感器是一种用途极广，很有发展潜力的传感器。典型的电容式传感器由上下电极、绝缘体和衬底构成。当薄膜受压力作用时，薄膜会发生一定的变形，因此，上下电极之间的距离发生一定的变化，从而使电容发生变化。但电容式压力传感器的电容与上下电极之间的距离的关系是非线性关系，因此，要用具有补偿功能的测量电路对输出电容进行非线性补偿。电容式传感器也常常被人们称为电容式物位计，电容式物位计的电容检测元件是根据圆筒形电容器原理进行工作的，电容器由两个绝缘的同轴圆柱极板内电极和外电极组成，在两筒之间充以介电常数为e的电解质时，两圆筒间的电容量为C=2∏eL/lnD/d，式中L为两筒相互重合部分的长度；D为外筒电极的直径；d为内筒电极的直径；e为中间介质的电介常数。在实际测量中D、d、e是基本不变的，故测得C即可知道液位的高低，这也是电容式传感器具有使用方便，结构简单和灵敏度高，价格便宜等特点的原因之一。电容式传感器与电阻式、电感式等传感器相比有如下一些优点：高阻抗、小功率,因而所需的输入力很小，输人能量也很低。电容式传感器因带电极板间静电引力极小(约几个10-5N)，因此所需输入能量极小，所以特别适宜用来解决输入能量低的测量问题，例如测量极低的压力、力和很小的加速度、位移等，可以做得很灵敏,分辨力非常，能感受0.001μm甚至更小的位移。温度稳定性好。传感器的电容值一般与电极材料无关，有利于选择温度系数低的材料，又因本身发热极小，对稳定性影响甚微。结构简单，适应性强，待测体是导体或半导体均可,可在恶劣环境中工作。电容式传感器结构简单,易于制造,可做得非常小巧，以实现某些特殊的测量;能工作在高低温、强辐射及强磁场等恶劣的环境中，也能对带有磁性的工件进行测量。动态响应好。由于极板间的静电引力很小，可动部分做得很小很薄，因此其固有频率很高，动态响应时间短，能在几兆赫的频率下工作，特别适合动态测量，如测量振动、瞬时压力等。电容式传感器的初始电容量很小,而传感器的引线电缆电容(lm~2m导线可达800pF)、测量电路的杂散电容以及传感器极板与其周围导体构成的电容等“寄生电容”却较大，这一方面降低了传感器的灵敏度;另一方面这些电容(如电缆电容)常常是随机变化的，将使传感器工作不稳定，影响测量精度，其变化量甚至超过被测量引起的电容变化量，致使传感器无法工作。因此对电缆的选择、安装、接法都要有要求。为减小电缆分布电容影响，可将电子线路的前级装在离传感器敏感部分很近的地方，或采用所谓“双层屏蔽等电位传输技术”，工作频率等于或接近谐振频率时，谐振频率破坏了电容的正常作用。因此，工作频率应该先择低于谐振频率。可以实现非接触测量，具有平均效应。例如非接触测量回转轴的振动或偏心、小型滚珠轴承的径向间隙等。当采用非接触测量时,电容式传感器具有平均效应，可以减小工作表面粗糙等对测量的影响。[详细]
