关键字：阀门定位器 http://www.azbil-china.com/ 智能 阀门定位器具有智能通讯和现场显示功能，便于维修人员对定位器工作情况进行检查维修。 由于智能阀门定位器的输入阻抗较高，而且随输入电流的增加而增大。因此在选用智能电气阀门定位器时一定要核对调节器输出控制信号的带负载能力，应大于500欧姆，才能保证大开度时定位器的正常工作。鉴于此，对于调节器输出控制信号带负载能力不够的情况，应考虑以下解决方案: 1)在阀门定位器输入信号回路中设置信号隔离器件，增加控制信号的带负载能力。即选用带负载能力高的中间隔离驱动器件，器件带载能力应大于500欧姆。如果现场是防爆场所则可选用带负载能力高的隔离式安全栅。 2)采用4线制连接方式，减小智能阀门定位器输入信号回路的输入阻抗。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.azbil-china.com/a/XWZX/301.htmlPARent;">ABSolute;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?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&dt=1600329004494&bpp=12&bdt=444&idt=21&shv=r20200914&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=8377863154543&frm=23&ife=1&pv=1&ga_vid=1589789806.1600329005&ga_sid=1600329005&ga_hid=923847775&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=8&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=1203&bih=586&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21067348&oid=3&pvsid=2884680127395849&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=0.10mpjggb2s3n&fsb=1&dtd=32" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.10mpjggb2s3n" data-load-complete="true"> |
