关键字：siemens定位器 http://www.siemens-positioner.com/ siemens定位器采用二位式压电阀控制，对气源质量的适应性好。在稳定状态时的气体能耗，而常规定位器喷嘴挡板需连续供给压缩空气，能耗较大。定位器在稳定状态下，由于关闭进气阀与放气阀，气能消耗接近为零。 siemens定位器对温度和振动耐受性强，常规定位器采用力平衡式原理，可动件较多，容易受影响。智能定位器采用温度影响小的标准电阻和特定电位器，受影响小。常规定位器无法适应多型号调节阀以及无法适应调节阀参数的改变，智能定位器通过人机界面设定，适合各种特性调节阀，并能动态的适应调节阀的控制参数的改变。 常规定位器采用喷嘴挡板，易被灰尘或污物颗粒堵住。siemens定位器运行中手动调整时控制回路连续性，常规定位器在手动调整时，需中断控制回路并使用减压阀等专用设备。在手动调整时，可利用面板上的按键进行在线调试。常规定位器的零点和行程调整需要人工反复调整，费时费力。siemens定位器的零点和行程调整可无需人工干预，自动进行标定。并且带有微处理器，容易实现附加功能。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.siemens-positioner.com/a/XWRD/272.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms 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?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1606809588617&bpp=18&bdt=319&idt=137&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=4893783601392&frm=23&ife=1&pv=1&ga_vid=1755132806.1606809589&ga_sid=1606809589&ga_hid=94557043&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=5&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=42530671%2C21066705&oid=3&pvsid=1311942099470835&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&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.rb3ich775v43&fsb=1&dtd=152" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.rb3ich775v43" data-load-complete="true"> |
