罗斯蒙特变送器电压变送器安装时，其输出为两线制4-20 mA，不需要单独的输出电源线，电缆可以使用便宜且较细的电线。这样可以节省电缆和安装成本。如果电源的输出电阻足够大，则由干扰源引起的电流会小，并且可以通过使用双绞线来降低干扰，从而使导体环路中的电压不会因磁场耦合而产生。其可以直接检测500 VAC，并将其转换为标准信号以实现分散检测，并具有分散检测和集中控制的优势。罗斯蒙特变送器在零电平上施加4 mA电流，电压传感器的输入，输出和电源完全隔离，性能稳定。电压转换器将高压电信号转换为低压信号并将它们彼此隔离。光电隔离器将电力系统的电压信号转换为低压信号并相互隔离。电压/频率变送器将电压信号转换为频率信号并相互隔离。将交流电压信号更改为直流信号，并将它们彼此隔离。027-88062221传真：027-88068180网址：http://www.whdkm.com/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%3A1048576%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=1619418355102&bpp=11&bdt=56&idt=109&shv=r20210422&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=8071552366500&frm=23&ife=1&pv=2&ga_vid=631198319.1619418355&ga_sid=1619418355&ga_hid=1624649066&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=1178&bih=801&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=2645251472780530&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=701%2C139%2C701%2C139%2C1920%2C0%2C1178%2C801%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=29&ifi=1&uci=1.v0njb51nfv12&dtd=126" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.v0njb51nfv12" data-load-complete="true"> |
