EJA隔膜密封式差压变送器的密封隔膜是用于防止管道中的介质直接进入变送器里的压力传感器组件中，它与变送器之间是靠注满流体的毛细管连接起来的。EJA118W、EJA118N和EJA118Y隔膜密封式差压变送器用于测量液体、气体和蒸汽的流量、液位、密度和压力，然后输出与测得的差压相对应的4~20mA DC信号。EJA118W、EJA118N和EJA118Y可与BRAINTM手操器、HARTO手操器(YHC4150X等)、CENTUMCSTM、FieldMate互相通讯，通过它们进行设定、监控等。参数：CPU或硬件出错时输出状态上限输出: 110%， 三21.6mA DC(标准)下限输出: -5%， ≤3.2mA DC- 2.5%，≤3.6mADC(适用于代码F1)注：只适用于输出信号代码为D和E时电源电压：10.5~42VDC(普通型和隔爆型)10.5~30V DC (本安型、n型或非易燃型)10.5~32V DC(带避雷保护时)10.5~28V DC(TIIS本安防爆)通信线路条件：电源电压: 16.4~42V DC(16.4~ 30V DC)注：如果是本安型变送器,外部负载电阻应包括安全栅电阻通信距离：2km,使用CEV电缆或者PVC电缆时负载电容：≤0.22μF负载电感：≤3.3mH与电源线的间距：≥15cm连接于接受电阻上的接收仪表的输入阻抗在2.4kHZ时，≥10khttp://www.wuhandekema.com/武汉德科蒙过程控制有限公司027-88062221传真：027-88068180。LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" 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=1624344710994&bpp=5&bdt=61&idt=201&shv=r20210617&cbv=%2Fr20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=2433662835556&frm=23&ife=1&pv=1&ga_vid=1437243715.1624344711&ga_sid=1624344711&ga_hid=717403285&ga_fc=0&nhd=1&u_tz=480&u_his=6&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=11&u_nmime=26&adx=-12245933&ady=-12245933&biw=1259&bih=816&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530671&oid=3&pvsid=2822094163339340&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=664%2C142%2C664%2C142%2C1920%2C0%2C1259%2C816%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=29&ifi=1&uci=1.92k5cp5qza6o&dtd=230" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.92k5cp5qza6o" data-load-complete="true"> |
