Description
技术背景
本发明涉及生产过程控制设备。更详细地说，涉及用于生产过程中测量各种参数(工艺过程变量)的测量变送器。
背景技术
测量变送器用于加工和制造设备中，例如，测量压力、湿度、流速、密度、粘度以及流体的许多其他化学、物理和电学特性。变送器专门安装在油罐、管道和其他流体容器上，并把表示流体特性的信号传送到遥控场所，例如控制室。
变送器通常包括用于传感器电路的传感器外壳和用于变送器电路的变送器外壳。两个外壳通过防火的机械接头连接在一起。通常，密封装置、软件和传感器电路与变送器电路之间的电连接装置不是标准化的产品，以至不能够实现组合来自不同生产线的组合传感器零件。
为了使布置的导线通过带螺纹的接头，传感器壳体的内侧专门应与变送器壳体内侧相连通。因为传感器壳体靠自身是不能与周围环境实现密封和防火的，而且，传感器电路是不能够远距离传输。不使用变送器壳体的话，在工厂环境中超越范围的直接布线到传感器壳体是不现实的。
在压力变送器的产品线内，最终使用者通常将需要能够组合多个部件，以获得压力区间、湿润材料和电子设备或显示装置的不同组合。另外，这种连接通常必须由制造者完成。然而，因为电子设备、软件和机械结构的不相容性，用户连接来自不同生产线的传感器和变送器零部件一般是不现实的。
为了增加功能和可量测性，需要变送器装置，在此，传感器部分可直接通过布线连接到控制系统或者使用局部区域总线的其他邻近的组件上，也需要变送器组件，这种变送器组件能够与来自其他生产线而无需最终用户加以显著改进的部件相连接。
发明内容
在许多方面，提供的组合传感器组件能够直接通过布线连接到控制系统或者其他临近的组件上。任选的可量测变送器组件能够连接到传感器组件上，以增加适合不同用途的功能和可量测性。传感器组件包括传感器输出端，配置的传感器输出端能够局部连接到可量测变送器组件上以形成一个变送器，或者通过布线直接连接到遥控接收装置上。组合传感器组件的壳体的空腔内装有电路，传感器能够测量过程变量。馈入装置密封能够与传感器组件外连接的壳体的接头。

具体实施方式
本发明提供用于生产过程中的新的传感器组件和变送器组件结构。这种新结构与典型的现有技术相比较是组合式的、易于测量的，并能够应用在大量的结构中。采用本发明，组合传感器组件(或“超级组件”)可单独用来测定和计量多种过程变量，或者能够与装入任选的变送器组件的“特性板”组合在一起使用。在操作期间，特性板能够用来显著提高超级组件随意应用于特殊用途或者随特殊应用的改变所需要的优越特性。这种模件性和可量测性降低了制造成本，减少了设备需要量。此外，能够向用户提供更多的结构选择，也减少了必需由用户购买的不同的特殊变送器配置的数目。传感器组件和变送器组件最好符合原设计的安全标准，在不把传感器组件和变送器组件从“区域”移开的情况下，能够一直保持测量性能。
图1为组合传感器组件10的简图，传感器组件10连接到可包括生产过程“流体”例如液体或气体的生产过程12(例如过程管)。组合传感器组件10通过歧管14连接到生产过程12，并且具体用来测定生产过程的过程变量。过程变量例如包括压力、湿度、流速、能级、PH值、传导率、混浊度、密度、浓度、化学成分，或者过程流体的其它特性。组合传感器组件10可包含一个或多个过程变量的传感器，并且包含输出接头或接头22，输出接头或接头22可用来与一个以上通讯标准相适应的通讯联络。
在图1所示实施例中，传感器组件10的输出接头连接到与公知的双线控制回路标准相适应的双线过程控制回路16上，例如4-20毫安回路、按照HART协议书操作的回路、按照区域总线、Profibus或其它协议书通讯联系的回路，等等。回路16连接到遥控地点例如控制室18，控制室18包含电源(未示出)，所以组件10能够从与其相连通的同一个回路16完全地获得动力，传感器组件10通常包含单个主体外壳20，主体外壳20具有适合连接到过程12和输出接头或接头22的过程连接件，接头22提供适于连接到不同类型装置或数据总线的一个以上不同类型输出。
图2示出本发明结构配置的另一个例子。在图2中，两只组合传感器组件10连接到局部总线26上，局部总线26保持与包含“特性板”的可量测变送器组件28相连通。特别是，总线26例如是符合控制器区域网络(CAN)协议书的一系列总线。变送器组件28可执行基于两只传感器组件10测量结果的另外的程序，或反之在过程控制环路16内提供通讯联络。例如，传感器组件10可以提供冗余测量结果或者提供多个测量结果，这样变送器组件28可计算多个先期过程参数，例如流率或液位。在特殊结构中，两只传感器组件显示整个孔板30上所测量的压差。然而，传感器组件10可测量任何类型的过程变量。在示于图7的另一个实施例中，传感器组件10直接固定到变送器组件，传感器组件本身可连接到另外的传感器组件上。
图1和图2所示的组合传感器组件10和变送器组件28的结构提供了很高的可量测设计性能。使用者可以配置适于简单安装的单个传感器组件10，用以测定过程变量。然而，适合更为先进构造的变送器组件28可以进一步提供更先进的能力(即“特性”)。例如，组件28可执行更超前的特征，或者把数据转换到适合在任何类型控制环路或数据总线16上传送的其它结构中。变送器组件28可以从多个备用信息源收集数据或者提供更超前的过程变量，例如流率，流率通过使用一定数量的不同过程变量能够计算出来。另一个例子是液面，若干过程变量是从过程容器上的多个测位的液面收集来的。变送器组件28也包括可视输出端32，例如液晶显示器，在此，能够直观提供数据或者工艺过程变量并且能够被操作者观察到。
在一种结构中，总线26也能够向组件28提供动力。在一些实施例中，变送器组件28自环路16获得自身的动力，因此，变送器28和组件10不需要再添加额外的动力接头。总线26也可以用作简单的通/断(打开/关闭)通讯联络或控制。在实施例中，这里的变送器组件28直接连接到传感器组件10，总线26用来作为内部数据总线。
组件10最好按照原有设计的安全标准配置，故能够用在危险的爆炸环境。简单的变送器组件28的结构是这样一种结构，组件28能够简单提供终端室，以容纳适合环路16布线和总线26布线的终端块(见图3C)。采用更先进的结构，变送器组件28可包含容纳布线的终端块和电路板的多个室。一些变送器组件28的功能度是由软件提供的，根据实际需要，软件可以被选择和/或装入组件28中。这样便会减少必须提供的不同硬设备选择件的数目，而且通过简单选择和把合适的软件装入组件28中可以获得各种结构。
图3A-3D示出的各种组件能够与本发明的可量测结构一起使用，例如，图3A示出组合传感器组件10A和10B。根据实际操作程序可以选择相应的传感器组件，例如，选择的传感器组件使其配置适合过程连接件、过程变量测量、过程变量范围、材料选择等方面。图3B举例说明电路板(即特性板)选择件36A和36B。电路板选择件36A和36B通常是变送器组件28的一部分。例如，选择板36A可提供可视显示或者选择板36B可提供特殊数据输出格式或过程变量补偿。图3C示出终端块选择件38A和38B。例如，按照特殊应用要求，终端块38A和38B能够提供不同数量的终端装置、各种类型的瞬态保护、硬件开关等。终端块38A和38B是变送器组件28的一部分。图3D示出可被选择用于特殊执行程序的变送器组件28的壳体选择件40A和40B。例如，根据需要单室或者双室壳体、所要求的各种不同壳体材料、所要求的不同直径或尺寸等，可选择壳体选择件40A和40B。壳体40A和40B构成变送器组件28的壳体。
图3E也示出本发明的可量测性。传感器组件10A和10B能够与选择板36A和壳体40A、40B的不同组合一起使用。快速接头41A、41B和41C能够直接用来连接到组件10A和10B。这种可量测性使得用户能够按照要求增加系统的特性或改变结构。
除了上面讨论的优点之外，本发明的可量测性特点使普通的特征板用于传感器系列中。传感器系列中的每个传感器组件能够提供不同的性能水平，并能够设计用于不同类型的过程流体或环境，和/或提供不同软件/硬件能力。普通特性板也可用于新的传感器组件设计中或配备用于测定新的过程变量的传感器组件结构。新特性板可添加到现存的传感器组件中，以提供新的能力，例如满足新的通讯联系协议书要求或识别功能。按照另一个实例，在一个独特结构中，具有潜在新功用的新特性板能够与多个传感器组件一起增加功能。
图4是简化方框图，示出按照一个特殊实施例的组合传感器组件10的各个组成部分。组件10专门包含一些类型传感器元件，例如压力传感器42。测量电路46基于由温度传感器44测得的温度而受到补偿的压力传感器42测量的结果向微型信息处理机48提供测量信号。微型信息处理机连接至作为一系列数据总线的局部区域总线26上。微型信息处理机48按照装入非易失存储器例如EEPROM50的指令运作，EEPROM也可以是只读存储器(ROM)。零间距和/或安全开关提供组件10的零和间距的配置。这些可以是连接到示于图1的接头22的打开/关闭开关。当配置的组件10在两线过程环路16上传输数据时，微型信息处理机48也可向所使用的MODAC52提供输出信号(MODAC是指包括模拟调制解调器和数字模拟转换器的ASIC。当然，其它结构也可用于本发明中)。配置的电路系统使用分流调节器控制通过环路16的电流，或者以数字方式向环路16传输数据。稳压器56连接到环线16或者变送器组件28，并且用来来向组件10内的电路提供稳定电压。MODAC52也有任选的用来标度输出信号的上/下标度输入端，时钟58例如用来控制MODAC52和微型信息处理机48的运作。在图4所示实施例中，提供的总数为5个输入/输出终端能够按照不同类型联络协议书予以配置。然而，可以使用任何数目的输入/输出终端。
图5是变送器组件28的简单方框示意图。组件28内的微型信息处理机60经由传感器组件输入/输出62连接到传感器组件10。传感器组件输入/输出62设置接头并且对接到如图4所示的一些或所有接头。例如，除了在总线26内提供一系列联络线路以外，还能够向过程控制环路16连接件上的传感器组件10提供动力。微型信息处理机60按照存储在存储器64中的指令以时钟66确定的速率运作。在使用环线输入/输出电路68的过程控制环路16上传送和接收数据。稳压器70作为动力源设置到变送器组件28内电路上。这种动力完全可以取自于环路16所获得的动力。
在制造期间，或者随后的提供不同特性的使用和与各种类型传感器组件10以及装在这些组件中的多个传感器共同操作期间，能够为存储器64编程。存储器64专门包含能够永久存储程序指令和数据的非易失存储器。需要的各种特性或者当结构和形状改变时，可以修改储存在存储器64中的微型信息处理机60的指令。变送器组件28能够用来提供具有按微型信息处理机60的程序指令执行的各种特性的标准平台。当然，各种硬件选择物品，例如局部显示器72或者特殊的输入/输出电路68也是可以获得的。然而，在一个例子中，配置的输入/输出电路68按照一些公知的标准操作，例如4-20毫安标准、HART联络协议书、现场总线协议书等。微型信息处理机60按照存入存储器64中的程序指令采用合适的协议书控制输入/输入出回路68。
图6至图13更详细地描述本发明结构的一些特殊执行装置。
图6示出组合传感器组件100的一个实施例的方框示意图，组合传感器组件100是图1中的组件10的一个特殊装置。组合传感器组件100包含支承空腔108内的组合传感器组件100的壳体102，并且设置连通至过程流体的过程开口104。过程开口104可以是法兰、管道等。壳体102有能够支承可量测变送器组件例如图2中组件28的接头110。接头110可以制作在或焊接在外壁106上，所以在接头110和外壁106之间的接合面不需要进行密封。接头110有伸入空腔108的开口112。
空腔108内的传感器组件电路114包含连通到过程开口104的传感器116。例如，电路114可设置如图4所示的若干部件。电路114产生表示过程变量特征的传感器输出118。
在接头110的开口112内的馈入装置120密封接头110，所以空腔108是防火焰的。组合传感器组件100完全被密封并且适合用在作为一个独立系统的场合，不需要安装变送器组件。馈入装置120具有激励电路114的外导管122，外导管122设置传感器输出端118并且接收设备配置的指令。
传感器输出端118能够配置成局部连接到可量测变送器组件28(图2)，也能够配置成直接布线连接到遥控接收装置，例如控制室18(图1)。输出端18可以是一个以上的接头。例如，可以是适合局部连接的一只接头或一组接头，一只接头或一组接头能够遥控连接。数字形信号可被输送到配置传感器输出的电路114上。在示出的特定装置中，配置的输出端118能够提供例如HART信号、4-20毫安模拟信号、基础场总线信号和其它类似信号，这一类信号能够远距离的传输到遥控接收装置。传感器输出端118可以设置用来向可量测变送器组件28或其它局部系统提供局部使用的信号，如CAN协议书信号。这样的传感器输出端通过电路114内的开关示意性地示出，而开关是由提供到微型信息处理机48以选择输出类型的配置指令控制的。
图7显示直接固定到可量测变送器组件132上的传感器组件130的横截面图。组件132是示于图5中的组件28的特定装置。在这个例子中，传感器组件130检测共面固定法兰134上的压差(P1-P2)。共面固定法兰采用螺栓固定到具有两个过程开口104的相搭配的共面入口法兰136上。绝缘体138使过程流体与传感器116隔绝。绝缘体138包括使传感器116与过程开口相连接的通道140。通道140具有防易燃的形状。绝缘体138也包含绝缘体隔膜片142，并且充以不可压缩流体，例如硅氧油。绝缘体144类似于绝缘体138。

图12是具有可移动盖的双室壳体194的分解图。空腔通向在第一和第二毂之间的壳体。终端块固定并密封在分隔壁195内。根据实际应用需要，通过选择终端块，例如，一个简单的两个终端的终端块196或者多于两个终端的终端块198，壳体194可进一步被标定。所选择终端块装入并密封两个室之间的开口200。
图13A和13B更详细示出插塞174。插塞174包括多只导管210，而图中示出三只导管。插塞174包括承载凸台212的弹簧，凸台212卡入位于接头110上的沟槽内，以把插塞174紧固在固定在接头110内，收缩管214置于导管210上，并且渐渐缩紧而形成缆索，以增加耐磨性。
