3051型压力变送器操作规程
3051型压力变送器测量原理3051 型变送器主要部件为传感器模块和电子元件外壳。
传感器模块包括充油传感器系统（隔离膜、充油系统和传感器）以及传感器电子元件。
传感器电子元件安装在传感器模块内并包括一温度传感器（电阻式测试检测器）、储存模块和电容/数字信号转换器（C/D 转换器）。
来自传感器模块的电子信号被传输到电子元件外壳中的输出电子元件。
电子元件外壳包括输出电子线路板（微处理器、储存模块、数字/模拟信号转换器或D/A 转换器）、本机零点及量程按钮和端子块。
3051CD 型变送器基本简图如图所示。
当油偏离中心膜时，改变电容信号。
然后该电容信号在C/D 转换器中被转换成数字信号。
随后微处理器从电阻式温度检测器和C/D 转换器中获取信号并计算出正确的变送器输出。
随后，该信号被送到D/A 转换器，D/A 转换器将信号转换回模拟信号并在4-20 mA 输出上叠加HART信号。
3051型压力变送器安装要求变送器和引压管线的安装对变送器的测量精度有很大的影响，因此在安装时应尽量靠近过程的地点并且采用最少的管线达到最佳精度。
并将变送器安装牢固以防止倾斜，变送器本体倾斜可导致变送器输出产生零点漂移。
同时变送器的安装应确保振动、冲击和温度变化达到最低。
当变送器安装在法兰一侧时，共面法兰定位时要确保正常排气或排液。
对于气体测量，排液/排气装置连接在底部，对于液体测量，排液/排气装置连接在顶部。
在投产前期严禁通过变送器冲洗引压管线。
对于蒸汽测量，首先应将变送器隔离然后再冲洗管线，在恢复测量前将管线再用水充满。
3051型压力变送器性能指标输出2 线4-20 mA，用户可选择线性或平方根输出。
数字过程变量可叠加在4-20 mA 信号上，任何符合HART 协议的主机都可使用。
电源需要外部电源。
标准变送器（4-20 mA）可在无负载情况下在电压达到10.5 至55 V dc 时运行。
最大负载最大回路电阻取决于外部电源的电压水平，最大回路电阻= 43.5参考精度±0.075% 量程阻尼对于阶式信号输入变化的模拟输出响应，用户可从0 到25.6 秒之间选择一时间常数。

3051压力变送器校验步骤Calibration Steps for the 3051 Pressure Transmitter3051压力变送器校验步骤Without using common transitional words, I will outline the steps to calibrate a 3051 pressure transmitter. Please note that these steps may vary depending on the specific model you are working with. It is important to refer to the manufacturer's instructions and guidelines beforeattempting any calibration procedures.在不使用常见的过渡词语的情况下，我将概述3051压力变送器的校准步骤。
请注意，这些步骤可能因您所使用的具体型号而有所不同。
在尝试任何校准程序之前，请参考制造商的说明和指南。
Step 1: Gather Necessary Equipment第一步：收集必要的设备Before starting the calibration process, ensure that you have all the necessary equipment ready. This typically includes a power supply, a digital multimeter, a pressure reference device (such as a deadweight tester or pressurecalibrator), appropriate cables and connectors, and any required calibration software.在开始校准过程之前，请确保您已准备好所有必要的设备。
375_常见操作和现场故障处理
375 手操器常见操作及现场故障处理怎样使用375HC 对3051系列进行组态调校? 3051C或其它压力变送器与375HART手操器的接线:现场可接在表的电源端子处,控制室可接在信号端子处. 回路电阻应保证在250Ω-----1000Ω的范围内.1.基本仪表组态或设定.2.仪表校验的方法及常见故障分析.仪表接线图375手操器1.基本仪表组态或设定.1. 打开电源开关. 等待375进入主菜单画面.2. 使用光标笔双击”HART 应用栏”! 如果手操器与变在线画面.送器通讯正常,则画面应转入则画面应转入在线画面此时,双击”仪表设置”即可进入变送器的组态菜单.仪表组态画面有5 个选项:1. 双击”显示过程变量”后, 您可以察看与变送器相关的所有测量参数.2. 进入诊断画面,您可以对仪表进行各种校验及回路测试,另外仪表的各项报警也可以外仪表的各项报警也可以查看查看!3. 进入”基本设置”您可以进行修改位号;工程单位;量程及仪表的阻尼系数;传递涵数.因此,这是最常用的菜单. 您可以双击5个选项的任一个进入该菜单!以下是菜单3:请注意: 单击左箭头可以退回上一级菜单, 单击”X”图标退回主菜单(此时可以关机单击”HOME”退回在线菜单(Online, 此菜单为实时参数更新画面)3-1: 修改单位:双击”单位”进入修改工程单位子菜单:3-1: 修改单位:使用光笔单击所选定的单位,然后单击”ENTER”,这时候会出现一个提示,告诉你当前过程变量在该选定单位尚未发送至变送器之前仍然为原单位,提示你应在下随菜单中进行发送(SEND).因此,见到提示后,即按OK 则出现下随菜单:此时单击”SEND”并在见到提示后,按OK,修该后的单位即下装到变送器中.3-1: 修改单位:最后见提示单击OK 完成该操作.(注意,单位Unit左上角”*”在发送成功后,应消失!)3-2: 修改量程:在基本设置中,用光标笔选中”3 量程”并双击,则进入量程修改菜单.在此菜单中,有两种修改方式.1.直接键盘输入.这是最方便的方式.2.提供标准压力值并将该压力确认为4 或20MA的设定点. 下面,为直接键盘输入方式:双击选项1.一般来说,如不做迁移,则只需修改量程上限.因此,双击”URV”进入键盘画面.您可以使用光笔,点击数字键直接输入希望修改的量程.然后点击”ENTER”确认.当返回上一级菜单后,单击”SEND”进行发送!见下图.(URV左上角*号表示该参数尚未发送!)发送后,有两个提示,请单击OK 确认即可!请按左键返回基本设置菜单(BASIC SETUP)进行下一步!3-3 :如何修改阻尼值?其方法和修改的量程方法一样. 此参数出厂设定为0.4秒!在基本设置中,选项2 是专门针对仪表的调校及故障诊断设置的.一般地说,变送器完成现场安装后,须进行读数的清零. 此功能在375 菜单中称之为:”ZERO RTIM”.以下为进入和完成该功能的步骤:由主菜单双击”仪表设置”即可进入上面的菜单.选中2 并双击,则进入诊断及服务子菜单. (见上图)仪表的校验选中3 并双击,弹出下面的菜单.选中3 并双击,弹出下面的菜单:选择1 并双击.然后点击OK.对两个提示进行确认,注意, 此项校准应确认在控制系统处于手动状态下进行并变送器处于零差压/压力下进行,绝压表不能进行此项操作.仪表的校验接下来,375将提示仪表应确认处于零点压力状态!即应该在现场操作人员配合下进行压力平衡或放空操作. 确认完成上述工作后,点击OK. 见下图:接下来的提示, 告诉您仪表需确认零点读数的稳定, 然后,点击OK 结束操作.最后的操作,应单击”HOME”键返回在线显示. 此时,PV 值应为零点值并且AO( 4-20MA)应为4.00MA.如PV 仍有误差,可再进行一次如PV 正确,但4.00MA 有误差,则需进行校验菜单的第2 项-Trim analog output/校准模拟量输出.双击选项1,确认系统处于手动状态,并将标准电流表串入变送器回路然后点击OK3 次.进入编辑菜单.使用光笔点击数字键,输入标准表的读数,例如:4.025MA.点击ENTER确认.接下来的提示将问你此时的输出是否与标准表一致.如一致,则选1/Yes.如不一致,则需重做,选2/No.下一步,将对20MA点进行相同的校准.孰不重复. 最后,使用HOME 键退回在线菜单即可.注意:为确保手操器与现场仪表通讯正常,请确认回路负载电阻为250-1000欧姆,且对大多数变送器来说,输出端应保证4MA /12V 的供电.(基本能量)如果变送器回路电缆受到强电干扰(例如与供电系统共用穿线管,则可能引起通讯问题.或回路电缆单端对地绝缘不良等).在有强干扰情况下,(例如有大功率变频器)应特别注意仪表的接地.2.仪表校验的方法及常见故障分析.2-1.* 压力变送器效验的基本条件:通常,仪表校验应在试验台上正常环境温度下进行.所使用的标准压力源的参考精度至少为被测表的3-4倍.电流标准应使用3位半以上的数字万用表.除此以外,275/375 HART 手操器是必备工具什么情况需要进行校验:常见的故障大致为:1.仪表PV值与实际压力不一致.2. 仪表PV值与实际压力一致,但4-20MA 输出与标准表不一致.3. 上述两个参数均对不上.以下分别针对这些问题进行分析解决.3051C型仪表是智能化变送器,感压膜头的信号首先通过A/D转换,接着由内部数据处理器将该信号通过标定曲线再转换为用户组态的压力变量(即PV值)进行显示.最后经D/A 转换形成4-20MA输出.当我们用手操器进行膜头校验时,实质上是对上述曲线进行矫正.我们称为:SENSOR TRIM!FULL TRIM 及ZERO TRIM 等.通常,这些操作菜单都在SENSOR TRIM下,具体选FULL TRIM 还是ZERO TRIM 要看具体误差的情况.但是,不同的变送器对曲线的矫正度有不同的限制,通常为满量程的3-5%!解决方案:使用ZERO TRIM,如果仪表在安装结束后,处于零点状态,或差压表虽为平衡状态,但管道内有静压,此时仪表的输出会有很小的偏差(0.25-0.31Kpa)视安装位置及仪表类型而不同,此时应使用ZERO TRIM进行矫正.这种操作仅对标定曲线进行平移,并不影响斜率,因此是针对D/A的单点校验.如果用户手头没有HART手操器,而且仪表本身具有外部零点调整按钮,此项矫正也可以通过激活(按住2秒以上)该外部按钮完成.所不同的是,这种操作只将当前的零位PV值调整为4MA,压力的读数并不改变!相当于进行了一次微量零点迁移.解决方案:使用FULL TRIM,此项调整为两点校验,需标准压力源进行打压,因此只能在离线情况下进行.此项操作为针对膜头内部A/D的校正.进行这一操作,必须先进行低端调整(Low sensor trim)再进行高端(Upper sensor Trim).进行FULL TRIM 以后,仪表的标定曲线完成了拟合.进入膜头校验菜单后(见下图)选中2,或直接按2键即可进入操作!解决方案:解决方案:低端标准压力可以是非零点,例如,对绝压表一般该压力为大气压力.(14.7 Psia)接下来进行上端标定即可.标定的容限一般不超过量程上限的+/_5%.超容限时,仪表会弹出操作报警提示.另外要注意的是,仪表必须是在解除写保护的情况下才能进行该项校正.正常情况下,完成了上述校验后,仪表的PV值应和标准一致,但并不能保证输出的正确性因此,一般地说还要进行模拟量输出矫正(Trim Analog Output).解决方案:C.4-20MA 输出校验.详见前述:D/A Trim 一节.D.如果出现这样的情况:即,PV 值正确,4-20MA输出电流值与标准表也附和,但PV值与4-20MA 不对应,而且是在零迁移情况下,例如:仪表量程为0-100Kpa,在零点情况下,手操器AO读数不是4MA例如:5.6MA,经与标准电流表复核,确为5.6MA.这种故障为内部电子电路故障无法恢复.E. 如果出现这样的情况:即,PV 值不正确,且无法经FULL TRIM 矫正,则多数为膜头损坏, 需进行特征化处理,这种维修应由工厂进行!F. 有些故障,仪表会弹出硬件报警,用户可以根据报警提示结合仪表操作手册中相关的解释进行排查.我公司提供对仪表的硬件维修服务。

罗斯蒙特3051C压力变送器校准调试方法
罗斯蒙特3051C压力变送器校准调试方法武汉德科玛2014-10-29 11:23:46罗斯蒙特3051C压力变送器的调试校准方法一．准备工作我们知道差压变送器在应用中是与导压管相连接的，通常的做法，需要把导压管和差压变送器的接头拆开，再接入压力源进行校准。
这样是很麻烦的，并且工作和劳动强度大，最担心的是拆装接头时把导压管扳断或出现泄漏问题。
我们知道不管什么型号的差压变送器，其正、负压室都有排气、排液阀或旋塞；这就为我们现场校准罗斯蒙特3051差压变送器提供了方便，也就是说不用拆除导压管就可校准差压变送器。
对差压变送器进行校准时，先把三阀组的正、负阀门关闭，打开平衡阀门，然后旋松排气、排液阀或旋塞放空，然后用自制的接头来代替接正压室的排气、排液阀或旋塞；而负压室则保持旋松状态，使其通大气。
压力源通过胶皮管与自制接头相连接，关闭平衡阀门，并检查气路密封情况，然后把电流表(电压表)、手操器接入变送器输出电路中，通电预热后开始校准。
二.常规差压变送器的校准先将阻尼调至零状态，先调零点，然后加满度压力调满量程，使输出为20mA,在现场调校讲的是快，在此介绍零点、量程的快速调校法。
调零点时对满度几乎没有影响，但调满度时对零点有影响，在不带迁移时其影响约为量程调整量的1／5，即量程向上调整1mA，零点将向上移动约0.2mA,反之亦然。
例如:输入满量程压力为100Kpa,该读数为19.900mA, 调量程电位器使输出为19.900+(20.000-19.900)*1.25=20.025mA.量程增加0.125mA，则零点增加1／5*0．125=0.025.调零点电位器使输出为20.000mA.零点和满量程调校正常后，再检查中间各刻度，看其是否超差?必要时进行微调。
然后进行迁移、线性、阻尼的调整工作。
三.罗斯蒙特3051智能差压变送器的校准用上述的常规方法对智能变送器进行校准是不行的，因为这是由HART变送器结构原理所决定了。
