关键字:abb阀门定位器 http://www.abb-positioner.com/ abb阀门定位器不仅仅提升了精度,也改善了稳定性。其现场测量装置会受到静态压力、温度、安装、振动、衰减、电磁相容性等因素的影响,这样会使其实际性能往往低于制造商声称的数字3-5倍。但是因为后期稳定性提高,精度提高,使这些因素对定位器的影响也慢慢变小。且定位器中的变送器得使用寿命内误差基本会保持在URL的0.15%以下,温度的影响被限制在最大0.15%。 abb阀门定位器外壳本身具有可拆卸的特点,可以在湿度为100%的情况下工作,也可以在拆除外壳的情况下使用。其所具有的抗侵入保护等级为P67,即使在最极端的温度下也便于读数。 abb阀门定位器的重量远远小于采用铝制外壳的仪器,虽然其使用的是不锈钢制成。其装置配有可编程的报警饱和限制、平方根取舍功能、自动修复数据库、可更换和可升级的电子器件、流量累加器、远程指示器选项以及高级内部诊断。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.abb-positioner.com/a/xwdt/151.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=1605855982111&bpp=12&bdt=1006&idt=131&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=1143445514992&frm=23&ife=1&pv=2&ga_vid=1053390698.1605855982&ga_sid=1605855982&ga_hid=890021944&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&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=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=77504340469926&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=2&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.opx4nmc4eog4&fsb=1&dtd=236" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.opx4nmc4eog4" data-load-complete="true"> |
