关键字：ABB阀门定位器 http://www.abb-positioner.com/ ABB阀门定位器由于是安装在气动调节阀上的，所以也会在环境较为苛刻的场所工作，包括环境温度、管道振动等因素都会对ABB阀门定位器正常工作带来不利影响。为了能够更好的适应这些环境，它设计了一些自身的诊断功能。1.自诊断功能：ABB阀门定位器的基本功能之一就是自诊断，自诊断在不影响正常工作情况下进行，常见的诊断有开机诊断、周期性诊断。2.传感器故障报警：ABB阀门定位器直接安装在调节阀上，受到调节阀振动的影响造成阀门定位器反馈部件失灵，如反馈杆松脱、线路故障、位置传感器自身故障等，ABB阀门定位器检测不到正常的反馈信号，它会发出一个报警信号，能够让用户及时发现问题所在。问题严重的话，会导致仪表直接停止工作。3.输入信号超出量程：ABB阀门定位器的输入信号是在一个范围内的，如果超出了控制信号超出设定值发出超量程报警信号，但是并不会停止工作，还会正常运行。德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱: sales@whdkm.com原文出处: http://www.abb-positioner.com/a/xwdt/106.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-pointer-lock allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&adsid=NT&dt=1596703224461&bpp=11&bdt=65&idt=221&shv=r20200803&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=4345116382717&frm=23&ife=1&pv=2&ga_vid=1500537745.1596703225&ga_sid=1596703225&ga_hid=178347261&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=9&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530557%2C42530559&oid=3&pvsid=1164377387994958&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.wsjp2iy291s0&fsb=1&dtd=284" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.wsjp2iy291s0" data-load-complete="true"> |
