电容式压力变送器在工业中的应用

电容式压力变送器在工业中的应用2010133027杨美玉电容式压力变送器在工业中的应用摘要:压力传送器是许多工业设备中用以控制工业过程和压力变化的重要原件。
随着科技的发展,它具有稳定性好,精度高等特点。
概述:电容式压力变送器是引进国外先进技术设备生产的新型变送器,关键原材料、元器件和零部件均采用进口,整机经过严格组装和测试,该产品具有设计原理先进、品种规格齐全、安装使用简便等特点。
由于该机型外观上完全融合了目前国内最为流行,并被广泛使用的两种压力变送器(罗斯蒙特3051与横河EJA),给使用者有耳目一新的感觉。
同时与传统的1151、CECC等系列产品在安装上可直接替换,故它是一些老型号产品的替化和更新产品。
为适合国内自动化水平的不断提高和发展,该系列压力变送器除设计小巧精致外,更推出具有HART 总线协议的智能化功能工作原理:电容式压力传送器被测介质的两种压力通入高、低两压力室,作用在δ元件(即敏感元件)的两侧隔离膜片上,通过隔被测介质的两种压力通入高、低两压力室,作用在δ元件(即敏感元件)的两侧隔离膜片上,离片和元件内的填充液传送到测量膜片两侧。
电容式压力变送器是由测量膜片与两侧绝缘片上的电极各组成一个电容器。
当两侧压力不一致时,致使测量膜片产生位移,其位移量和压力差成正比,故两侧电容量就不等,通过振荡和解调环节,转换成与压力成正比的信号。
电容式压力变送器和电容式绝对压力变送器的工作原理和差压变送器相同,所不同的是低压室压力是大气压或真空。
电容式压力变送器的A/D转换器将解调器的电流转换成数字信号,其值被微处理器用来判定输入压力值。
微处理器控制变送器的工作。
另外,它进行传感器线性化。
重置测量范围。
工程单位换算、阻尼、开方,,传感器微调等运算,以及诊断和数字通信。
电路中由于采用了检波及模数转换环节从而限制了电路的响应速度,图3所示的振荡型信号处理电路可以在一定程度上解决这个问题其主要部分是积分器A2、比较器A1 微分器A3和反相放大器A4完成差动电容比铡运算的辅助作用由电路分析可知.A1、A2组成了一个张驰振荡器.A1输出v1 (t)为正负交替的方波,而V (t)为同频率的三角波。

1、大庆油田天然气分公司油气加工五大队2、大庆油田钻探井下作业工程公司压裂三队3、大庆油田天然气分公司生产维修大队前言压力变送器的第一代产品是模拟变送器,第二代产品是智能变送器,所谓智能的概念是:传感器和变送器是由微处理器驱动,并且具有通讯和自我诊断的能力。
智能压力变送器除了有高精确度、大量程比和高稳定性外,它一般带有HART协议。
它可以用275或375手操器实现远程设定或修改变送器的组态数据。
在这里重点介绍一下油气加工生产装置中使用较多的3051系列智能压力(差压)变送器。
一、变送器的特点:罗斯蒙特3051系列差压变送器是一种高性能两线制变送器。
它属于一种智能型的电容式变送器,由传感组件和电子组件两部分组成。
将超级模块与单一电子板线路安置于全焊接真空密封的不锈钢体中,消除了湿度与现场恶劣环境的影响。
二、编程组态3051智能压力(差压)变送器采用HART协议进行通讯,该协议使用了工业标准Bell202频移调制(FSK)技术。
在模拟输出上叠加高频信号可以进行远程通讯。
罗斯蒙特采用该技术,能在不影响回路完整性的的情况下,实现同时通讯和输出。
其编程组态接线简单方便,回路电阻应保证在250~1000Ω 的范围内。
使用HART协议对3051型压力变送器进行组态,能保证测量仪表设备稳定准确运行。
通常我们应用HART275或 375 手操器可以查看变送器的相关信息,也可以对变送器进行编程组态。
对位号、工程单位、测量上下限、阻尼、传感器调零、输出设置、表头选项设置等信息进行查看和修订。
罗斯蒙特3051系列变送器的使用体会

罗斯蒙特3051系列变送器的使用体会压力、差压变送器是化工自动控制中使用最多的测量仪表之一。
在现代化连续生产过程中,变送器的可靠性将会影响生产工艺过程。
这种影响有时可能是严重的,所以,仪表工程师都面临一个共同的问题----如何选择一种好的、可靠的压力、差压变送器。
在我们的扬子巴斯夫苯乙烯工程中,需要使用近480台各种压力、差压变送器。
它们几乎包含了压力、差压变送器的各种应用:压力、差压、绝压、高压、微差压、高温、低温、各种材质及特殊加工的远传法兰型压力变送器,我们的工程筹建部在几种著名品牌的变送器中经过反复调查,比较后,决定使用罗斯蒙特公司的3051系列变送器。
根据罗斯蒙特公司介绍:3051系列变送器是目前世界上最好的变送器,精度为0.075%。
量程比为100:1。
稳定性:0.1%一年、0.25%五年。
到目前为止,没有一种变送器能全面达到这样好的指标。
罗斯蒙特公司宣传3051是“隐形变送器”。
因为3051有非常好的可靠性和稳定性。
安装调试好以后,在五年左右时间内,基本不会有什么问题,几乎没有标定,维修的工作量。
象不存在一样,所以叫“隐形变送器”。
我们在以前工厂中也使用过多种品牌的智能变送器,在使用罗斯蒙特3051变送器一年多时间后,我们感到3051确实是一种非常好的变送器。
技术上的优势是明显的。
我们使用罗斯蒙特3051系列变送器的经验是:1.高度的可靠性在安装调试投入使用的近两年时间内,四百多台3051变送器经受了考验,在各种各样的应用中,没有一台出现过问题,保证了我们试车、生产的顺利进行。
所以我们对3051变送器的质量感到满意和放心。
2.极好的稳定性变送器的测量会随着环境温度、过程温度、静压的变化而发生漂移,如果在一些微小的压力、差压测量场合,这个漂移很可能是比较严重的,会存在一个很大的误差。
但3051变送器由于具有独特的传感器结构,摩托罗拉专用芯片的电子制造工艺,使得这种漂移降到很低的程序(0.2%56度,0.2%70公斤)。

化学品制造商利用低压系列压力变送器改善了过程利用率-罗斯蒙特3051S

∙每个变送器使校准及调试时间减少了67%
∙每台装置使安装总成本减少了2,000美元
∙改善了过程利用率
北美一家大型的化学品制造商
挑战
环保局严格的排放控制标准要求对每个变送器都应进行常规校准。
违反此类标准的代价高达数万美元,因此为精确测量提出了更高的要求。
该公司的废气收集、稀释及焚烧过程涉及多项操作。
一系列排气收集装置负责收集化学品罐的VOC,同时补充空气稀释混合气体,使其控制在复合化学品最低爆炸限值的25%之内。
之后,混合气体流经皮托管阵列至热氧化器并从烟囱排出。
如未正确稀释,混合气体会发生爆炸,破坏工厂并造成潜在的严重伤害。
收集与稀释过程中空气流速非常低,形成的差压不超过1.5英寸H2O。
当工厂设计并安装首台热氧化器时,可充分控制此类较小校准量程的DP变送器只有用于HVAC设施的变送器。
之前安装的HVAC变送器运行良好,但需要大量时间及人力保持正确校准。
由于校准程序过于复杂,每台HVAC变送器的维护时间长达45分钟。
解决方案
低压系列Rosemount 3051S 的安装解决了这些重要的性能、维护及安装难题。
直观的设备界面与简便的维护程序将调试与校准时间从45 分钟减少至 15 分钟。
而且,与 4 线技术相比,通过使用2 线技术,每台变送器的安装成本减少约2,000美元。
凭借室内安装与控制,3051S 实现了化学品制造商要求的可靠性及精准性。
