关键字:雷达物位计 http://www.dkmcn.com/ 高频雷达物位计机身采取一体化的设计,降低在使用过程中的机械磨损降低,延长使用寿命。其主要的工作原理分两种,分别是调频式和脉冲式。调频式的功耗大,必须要用四线制,且电子电路比较复杂,相比下,脉冲式的功耗低,而且准确度较高,使用二线制供电即可,更加安全,适用范围更广。高频雷达物位计的工作过程是“发射—反射—接收”的模式,电磁波从发射到接收的时间与到液面的距离成正比。并且不需介质进行传播,在真空环境中同样可以进行测量,且具有不受大气、蒸气、挥发雾等测量介质的影响特点,能在易挥发的介质下应用。除此之外,高频雷达物位计测量方式采用是非接触式测量,可以不被测量介质的物理、化学特性影响;测量范围大,在高温、高压的液位下同样可以测量,对于产生的虚假声波可以调试消除。在制作天线是,采用的高质量材料,确保仪器关键部件的抗腐蚀能力。高频雷达物位计对于测量的介电常数要求及低,通常情况下,介电常数越大,反射信号越强。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.dkmcn.com/news_show.asp?id=957ABSolute;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=1607415072390&bpp=13&bdt=1229&idt=299&shv=r20201203&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=5599937226409&frm=23&ife=1&pv=2&ga_vid=1240502916.1607415073&ga_sid=1607415073&ga_hid=972221409&ga_fc=0&nhd=1&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&eid=21066699%2C21066792%2C42530671&oid=2&pvsid=1724421591189737&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.glkb0cdikdwf&fsb=1&dtd=477" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.glkb0cdikdwf" data-load-complete="true"> |
