横河eja变送器能够将传感器的输出信号转换为可以被控制器接受的标准化信号的设备。主要由传感器、测量转换电路、补偿电路等组成。不同的物理量需要不同的传感器和相应的变送器。用于工业控制的变送器主要有:温度变送器、压力变送器、流量变送器、液位变送器、电流变送器、电压变送器等。横河eja变送器具有输入过载保护、输出过电流保护、输出电流长时间短路保护、输出端口瞬态感应雷与浪涌电流TV S抑制保护、工作电源过压极限保护、工作电源反接保护等。压力变送器是一种能将接收的气体、液体等压力信号转换为可传送的标准化输出信号的仪器。此外，其输出信号与压力之间有一给定的连续函数关系(通常为线性函数)。主要用于工业过程压力参数的测量与控制，其中的差压变送器也常用于液位和流量的测量。http://www.wuhandekema.com/武汉德科蒙过程控制有限公司027-88062221传真：027-88068180。ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" 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%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%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&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1609831428022&bpp=19&bdt=240&idt=194&shv=r20201203&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=3067735419143&frm=23&ife=1&pv=2&ga_vid=302854421.1609831428&ga_sid=1609831428&ga_hid=22618246&ga_fc=0&nhd=1&u_tz=480&u_his=4&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=1257&bih=828&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530671%2C21066923&oid=3&pvsid=1122140003447335&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1920&brdim=759%2C139%2C759%2C139%2C1920%2C0%2C1278%2C828%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=29&ifi=0&uci=0.igiwuoq12kiy&dtd=236" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.igiwuoq12kiy" data-load-complete="true"> |
