关键字:罗斯蒙特压力变送器http://www.yp3051.com/ 罗斯蒙特压力变送器是过程控制系统的检测变换部分,将液体、气体或蒸汽的差压(压力)、流量、液位等工艺参数转换成统一的标准信号,作为显示仪表、运算器和调节器的输入信号,以实现生产过程的连续检测和自动控制。罗斯蒙特压力变送器低压侧压力口(大气压参考端)位于压力变送器的脖颈处,在电子外壳的后面。此压力口的通道位于外壳和压力传感器之间,在变送器上360°环绕。保持通道的畅通,包括但不限于由于安装变送器时产生的喷漆,灰尘和润滑脂,以至于保证过程通畅。罗斯蒙特压力变送器的电气接线主要是以下的过程:①拆下标记“FIELD TERMINALS”电子外壳。②将正极导线接到“PWR/COMN”接线端子上,负极导线接到“-”接线端子上。注意不得将带电信号线与测试端子(test)相连,因通电将损坏测试线路中的测试二极管。应使用屏蔽的双绞线以获得最佳的测量效果,为了保证正确通讯,应使用24AWG或更高的电缆线。③用导管塞将变送器壳体上未使用的导管接口密封。④重新拧上表盖。手机:13968728530地址:乐清市柳市镇柳翁路65号ABSolute;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%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=28.0.0&pra=5&wgl=1&dt=1618558275427&bpp=13&bdt=64&idt=68&shv=r20210414&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Db656b6bb827fc305-22e2b0f20bc400a4%3AT%3D1602660174%3ART%3D1602660174%3AS%3DALNI_MZRQsPf2qOvf5Ld0nQ2AHzdd2m-cw&nras=1&correlator=8556091976576&frm=23&ife=1&pv=2&ga_vid=713299078.1618558276&ga_sid=1618558276&ga_hid=1278719192&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=13&u_nmime=28&adx=-12245933&ady=-12245933&biw=1464&bih=679&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44735932%2C44736524%2C44740079&oid=3&pvsid=4438175001697352&pem=719&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1664&brdim=0%2C119%2C0%2C119%2C1920%2C0%2C1920%2C883%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=31&ifi=1&uci=1.fzzba89b7v4o&fsb=1&dtd=90" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.fzzba89b7v4o" data-load-complete="true"> |
