本文关键字：罗斯蒙特 http://china-rosemount.cn/ 检定0.5级以上的罗斯蒙特压力变送器时，需用二等标准活塞式压力计作为标准器，而活塞式压力计能够测量的压力值是不连续的，所以在检定压力变送器时，要根据压力变送器的量程和活塞式压力计输出压力的可能，确定5个或5个以上的检定点。确定好检定点后，可算出各检定点压力变送器对应的输出电流值，将其作为真值(或实际值)。按确定的检定点进行检定。检定时，压力变送器的实际输出值(标准亳安表的示值)作为测得值(或示值)将二者进行比较即可求出压力变送器的示值误差。当检定1级以下的罗斯蒙特压力变送器时，可以使用弹簧管式精密压力表作力标准器。此时，也不一定要一律均分 成5个检定点，而要根据精密压力表的读数方便(按精密压力表的刻度线)来确定检定点，只要不少于5点就行。上海蒙研自动化设备有限公司地址：上海松江广富林路639号嘉鸿大厦1119室联系人：徐工手机：18616582302 / 18616582330QQ：764861476邮箱：sales@shmyzdh.comABSolute;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%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&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=1603958535775&bpp=13&bdt=377&idt=84&shv=r20201026&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D6865202515317345-2229dfe072c400c7%3AT%3D1603958520%3ART%3D1603958520%3AS%3DALNI_MbCGtrHioaRH0OnQC5hoGCbqxcKkA&nras=1&correlator=8710262879479&frm=23&ife=1&pv=2&ga_vid=308818645.1603958536&ga_sid=1603958536&ga_hid=1184183035&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=4&u_java=0&u_h=900&u_w=1440&u_ah=860&u_aw=1440&u_cd=24&u_nplug=22&u_nmime=41&adx=-12245933&ady=-12245933&biw=1440&bih=741&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530671%2C21067166&oid=3&pvsid=4055131665961734&pem=34&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1440%2C0%2C1440%2C860%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.ps0ity5fg58i&fsb=1&dtd=149" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.ps0ity5fg58i" data-load-complete="true"> |
