关键字：雷达液位计 http://www.dkmcn.com/ 雷达液位计适用于酸碱储罐、固体颗粒、浆料储罐、小型储油罐，各类导电、非导电介质、腐蚀性介质。比如煤仓、灰仓、油罐、酸罐等。雷达液位计之所能够广泛的适用各大场合还离不开它丰富的种类，下面一起看看高频型的工作原理。雷达液位计工作的基本原理是发射－反射－接收。雷达传感器的天线以波束的形式发射最小5.8GHz的雷达信号。反射回来的信号仍由天线接收，雷达液位计雷达脉冲信号从发射到接收的运行时间与传感器到介质表面的距离以及物位成比例。即：h= H–vt/2式中 h为料位；H为槽高； v为雷达波速度；t为雷达波发射到接收的间隔时间高频雷达液位计的雷达波是一种特殊形式的电磁波，雷达料位计利用了电磁波的特殊性能来进行料位检测。电磁波的物理特性与可见光相似，传播速度相当于光速。其频率为300MHz-3000GHz。电磁波可以穿透空间蒸汽、粉尘等干扰源，遇到障碍物易于被反射，被测介质导电性越好或介电常数越大，回波信号的反射效果越好。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.dkmcn.com/News_show.asp?id=853PARent;">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%3A32768%2C9%3A32776%2C10%3A32%2C11%3A32%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=32.0.0&pra=5&wgl=1&dt=1593765427741&bpp=3&bdt=146&idt=230&shv=r20200624&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=6636877273248&frm=23&ife=1&pv=2&ga_vid=710631622.1593765428&ga_sid=1593765428&ga_hid=2077120350&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=5&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&eid=21065532%2C42530494%2C42530496%2C42530500%2C42530502&oid=3&pvsid=426965755428247&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%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=8220&bc=31&ifi=0&uci=0.2ru721sa9vjv&fsb=1&dtd=282" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.2ru721sa9vjv" data-load-complete="true"> |
