关键字:E+H超声波液位计 http://www.dkmeh.com/ E+H超声波液位计可分为两种,分别是一体式超声波液位计和分体式超声波液位计。分体式液位计是指电子单元探头之间由电缆相互连接,探头可以安装在容器顶端,电子单元能灵活地选择其他安装位置,方便读取观察、容易操作。一体式液位计是电子单元和探头为一个整体,安装简便,方便安装在容器的顶部。 不论是哪种形式的E+H超声波液位计,他的工作原理都是由探头发出脉冲在被测介质表面反射回来,被转换成电子信号,测量出介质的物位高度。在工作原理上,E+H超声波液位计适用于水利、石油化工和污水处理、采用的非接触式测量。探头向被测物体发射脉冲,脉冲到介质表面后反射回来,再被探头接收。从发射到反射时间,与探头到介质的距离成为正比。 超声波与雷达相比,价格上较低,雷达更为精密,因此价格较高。这是要根据工况进行选择,不能但因价格选择决定。E+H超声波液位计应用范围广泛,主要应用的场合为:化工石油、医药生产、造纸行业、水利电力、污水处理、食品加工、酒类饮品、钢铁行业。 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.dkmeh.com/a/news/559.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=1606291534531&bpp=2&bdt=1457&idt=166&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=1535734183190&frm=23&ife=1&pv=1&ga_vid=1888925617.1606291535&ga_sid=1606291535&ga_hid=213507763&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=2285711517885481&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=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.hmsvp29z1tqg&fsb=1&dtd=200" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.hmsvp29z1tqg" data-load-complete="true"> |
