高准流量计的流量信号线需要与分体型转换器与传感器配套使用时,流量信号传输电缆可以使用型号为RVVP2X32/0. 2的聚氯乙烯护套金属网屏蔽信号电缆。使用长度一般不大于100m。信号线在订货时注明长度,与传感器配套出厂。转换器提供有等电位激励屏蔽信号输出电压,以降低电缆传输的分布电容对流量信号测量的影响。当被测电导率小于50μS /cm或长距离传输时,可使用具有等电位屏蔽的双芯双重屏蔽信号电缆。如专用电缆或BTS型三重屏蔽信号电缆。高准流量计的流量信号线的励磁电流线可采用二芯绝缘橡皮软电缆线,励磁电流线的长度与信号电缆长度一致。当使用3200专用电缆时,励磁电缆与信号电缆合并为一根。所有输出与电源线由用户根据实际情况自备。但请注意满足负载电流的要求。电源线可采用二芯绝缘橡皮软电缆线,于直流供电转换器,应注意到电线电阻与电源电压有关,一般在24V供电电缆电阻不应大于100。电源线的电阻值由导线的长度和截面决定。使用电流输出线时,应注意到导线的电阻与负载电阻之和不得大于7500。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?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A8%2C2%3A8%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%2C32%3A32%2C40%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&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1609383562084&bpp=2&bdt=205&idt=211&shv=r20201203&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff-22ed306a0ec40076%3AT%3D1602729171%3ART%3D1602729171%3AS%3DALNI_MbBh5yg2uKd0UtH0u1Ylcdyq42wTg&nras=1&correlator=8621523654960&frm=23&ife=1&pv=1&ga_vid=343838387.1609383562&ga_sid=1609383562&ga_hid=1036368731&ga_fc=0&nhd=1&u_tz=480&u_his=9&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=861&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=445213274159741&pem=217&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=692%2C18%2C692%2C18%2C1920%2C0%2C1227%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=9228&bc=31&ifi=0&uci=0.d9pz7yaxw8ow&fsb=1&dtd=232" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.d9pz7yaxw8ow" data-load-complete="true"> |
