艾默生流量计电磁流量仪适用于测量封闭管道流量中导电液体和浆液的体积,如清水、污水、各种酸、碱和盐溶液、浆液、浆液、纸浆、糖浆和食用液体等。其测量原理是基于电磁感应原理的法拉第定律:当导电液体在磁场中运动以切断磁力线时,导体中产生感应电势。在测量流量期间,导电液体以速度V流过垂直于流动方向的磁场。导电液体的流动感应出与平均流速成比例的电压。感应电压信号通过与液体直接接触的两个或多个电极检测,并通过电缆发送到转换器。通过智能处理,液晶显示器显示或转换成标准信号4-20mA和0-1kHz输出。 艾默生流量计电磁流量计待测流体必须具有一定的电导率,电导率5S/cm。保护等级:IP65:防喷水型,允许水龙头从任何方向向传感器喷水,喷水压力为30千帕,输出水量为2.5升/分钟,距离为3米;IP68:潜水型,长时间在水中工作。保护等级应根据实际情况选择。如果传感器安装在地下并且经常被淹没,应选择IP68。如果传感器安装在地面上,应选择IP65。 http://www.whamri.com/电话:027-87263542手机:18372021864ABSolute;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?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A8%2C2%3A8%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&dt=1617258498515&bpp=7&bdt=278&idt=52&shv=r20210329&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff-22ed306a0ec40076%3AT%3D1602729171%3ART%3D1602729171%3AS%3DALNI_MbBh5yg2uKd0UtH0u1Ylcdyq42wTg&nras=1&correlator=3554416914238&frm=23&ife=1&pv=1&ga_vid=1917825206.1617258499&ga_sid=1617258499&ga_hid=2092642139&ga_fc=0&nhd=1&u_tz=480&u_his=8&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=14&u_nmime=31&adx=-12245933&ady=-12245933&biw=990&bih=653&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44735932%2C44740079%2C44739387&oid=3&pvsid=2837233762328872&pem=217&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=375%2C0%2C375%2C0%2C1920%2C0%2C1501%2C1084%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8196&bc=31&ifi=1&uci=1.680inutum2vb&fsb=1&dtd=64" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.680inutum2vb" data-load-complete="true"> |
