关键字：阀门定位器 http://www.azbil-china.com/ 阀门定位器中不需要人工调校，就可以自动检测所带调节阀零点，满程，摩擦系数，自动设置控制参数的被成为智能阀门定位器。 智能阀门定位器通常我们按照两个标准来分： 1.按隔爆级别分：可分为隔爆和不隔爆。 隔爆的阀门定位器是不透明外壳的，一般是黑色的外壳；普通的是透明外壳能看到它内部的结构。拿YTC来看，隔爆的是YT2400；不隔爆的是YT2300 2.按供电方式可分为：单独供电和不用单独供电。 阀门定位器有一个24VDC和一个4~20mA电流信号，这样才能自检；YT2300定位器就不用有24VDC供电，只需要一个4~20mA的电流信号就能自检。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.azbil-china.com/a/XWZX/262.htmlPARent;">ABSolute;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%2C8%3A32776%2C9%3A32776%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=29.0.0&pra=5&wgl=1&adsid=NT&dt=1589270059779&bpp=14&bdt=491&idt=291&shv=r20200506&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&crv=1&nras=1&correlator=48478401925&frm=23&ife=1&pv=2&ga_vid=994082908.1589270060&ga_sid=1589270060&ga_hid=503573405&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=4&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=16&u_nmime=33&adx=-12245933&ady=-12245933&biw=1286&bih=626&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065532%2C21066085%2C44716867%2C42631002&oid=3&pvsid=3575000603513551&pem=851&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=8220&bc=31&ifi=0&uci=0.2p5vc4r33uqj&fsb=1&dtd=334" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.2p5vc4r33uqj" data-load-complete="true"> |
