关键字：E+H超声波液位计 http://www.dkmeh.com/ E+H超声波液位计是一款由微处理器控制的数字液位仪表，由三部分组成，分别是超声波换能器(探头)、驱动电路(模块)、子液晶显示模块。 E+H超声波液位计在测量中超声波脉冲由传感器(换能器)发出，声波经液体表面反射后被同一传感器接收，通过压电晶体转换成电信号，并由声波的发射和接收之间的时间来计算传感器到被测液体表面的距离。由于采用非接触的测量，被测介质几乎不受限制，可广泛用于各种液体和固体物料高度的测量。 E+H超声波液位计在进行调试的时候探头固定安装在水面观测点上方，垂直对准水面向水面发射超声波，超声波到达水面后部分能经水面反射，被探头接收，仪表记下这段时间t;探头内部安装有温度传感器，根据超声波的传播速度和时间t，经过温度补偿计算出水面到探头的距离D。SANs-serif" style="overflow-wrap: break-word;">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/612.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%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%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&dt=1613724227529&bpp=9&bdt=510&idt=85&shv=r20210211&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=4300972835855&frm=23&ife=1&pv=2&ga_vid=1161785123.1613724228&ga_sid=1613724228&ga_hid=2082796731&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=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530671%2C21068495%2C21068769%2C21068893&oid=3&pvsid=2719786410215092&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=1&uci=1.59jwbqc6a40y&fsb=1&dtd=112" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.59jwbqc6a40y" data-load-complete="true"> |
