abb阀门定位器除了能将电信号转换为气信号外,还能够使阀杆位移与输入信号大小保持线性关系,即实现控制器来的输入信号与阀门位置之间关系的准确定位,它将电气转换与阀门定位的功能组合在一起,在工程实际应用中被广泛使用。气动阀门定位器的输入信号一般来自电气转换器或气动控制器,其输入信号一般为标准信号20~100kPa,其具有工作可靠,抗环境温度、湿度、电磁干扰力强等特点。 abb阀门定位器应用在控制系统中,如果使用的控制器是电动仪表,输出的信号是0~10mmA DC或4~20mmA DC,我们应使用电气转换器,将0~10mmA DC或4~20mmA DC信号转换为20~100kPa输入到气动阀门定位器,由此来控制气动执行机构。在控制系统中,如果使用的控制器是气动仪表,输出的信号为20~100kPa,我们可将20~100kPa信号输入到气动阀门定位器,由此来控制气动执行机构。http://www.positioner-abb.com/电话:027-87263542手机:18372021864ABSolute;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%3A1048576%2C32%3A32%2C40%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1607310423128&bpp=3&bdt=40&idt=141&shv=r20201201&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff-22ed306a0ec40076%3AT%3D1602729171%3ART%3D1602729171%3AS%3DALNI_MbBh5yg2uKd0UtH0u1Ylcdyq42wTg&nras=1&correlator=2614885445625&frm=23&ife=1&pv=2&ga_vid=1613088710.1607310423&ga_sid=1607310423&ga_hid=976802911&ga_fc=0&nhd=1&u_tz=480&u_his=7&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=14&u_nmime=31&adx=-12245933&ady=-12245933&biw=1086&bih=763&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=3226673665861673&pem=217&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1664&brdim=690%2C0%2C690%2C0%2C1920%2C0%2C1249%2C1014%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.xy6pvf6t80bc&fsb=1&dtd=187" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.xy6pvf6t80bc" data-load-complete="true"> |
