关键字:阀门定位器 http://www.samson-china.com/ 智能电-气阀门定位器是新一代的、智能化的用于气动执行机构的阀门定位器。产品集自校正功能、自诊断功能、故障报警功能、阀位模拟信号反馈功能及多种特性修正功能于一身,菜单操作,便于现场安装、调试。能广泛用于电力、冶金、石化、轻纺、食品、医药等行业。 由于智能型阀广定位器采用二线制供电。4~20mA的信号经过DC/DC转换后需要产生两组电压,分别供给电子器件和压电阀使用,难度较大。为了解决这一问题,可以采用以下的方法应对: 1.尽可能提高DC/DC的效率,选用优质磁芯材料,合理设置振荡频率等方法实现; 2.采用低功耗器件,并尽可能的采用低工作电压、系统时钟频率以满足最低实时性要求; 3.阀门定位器的软件配合。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地址:武汉市武昌区中南国际城D座一单元901室原文出处:http://www.samson-china.com/a/xwzx/316.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?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%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&dt=1614586403170&bpp=7&bdt=162&idt=141&shv=r20210224&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=5752301239642&frm=23&ife=1&pv=2&ga_vid=147034636.1614586403&ga_sid=1614586403&ga_hid=739356263&ga_fc=0&nhd=1&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=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21068946&oid=3&pvsid=3936128959666194&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=1&uci=1.cewi27gj702q&fsb=1&dtd=222" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.cewi27gj702q" data-load-complete="true"> |
