压力型罗斯蒙特变送器有不同类型,分别应用于不同的场合,其工作原理不尽相同。如:压阻式变送器是将压力作用到膜片的前表面,在压力作用下膜片会出现一定的形变,感压膜片的背面印有厚膜电阻,进而形成一个惠斯通电桥,在压阻效应下,电桥会产生相应的电压信号,该信号与激励电压成正比例关系。压力型罗斯蒙特变送器压电式变送器是利用正压电效应研制出来的,正高压电效应就是将一定的外力作用于电解质使其发生变形,电解质内部会出现极化现象,并且在其两个表面会产生正负不同的电荷,外力停止作用时,电解质又恢复到不带电的状态。电荷的极性会随着作用力方向的改变而改变。在电解质极性方向施加电场,电解质也会发生变形,撤销后电解质的形变消失,这就是逆压电效应。027-88062221传真:027-88068180网址:http://www.whdkm.com/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%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=1622599315657&bpp=2&bdt=141&idt=74&shv=r20210525&cbv=%2Fr20190131&ptt=9&saldr=aa&cookie=ID%3Df208fc56032ec04a-222ab57211c400ce%3AT%3D1602655468%3ART%3D1602655468%3AS%3DALNI_MZ90KP_NdNDKAtfzA4A4RaK0MMehQ&nras=1&correlator=7200572091102&frm=23&ife=1&pv=2&ga_vid=1442093224.1622599316&ga_sid=1622599316&ga_hid=254384253&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=1028&bih=801&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31060974&oid=3&pvsid=1100147276680097&pem=596&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=866%2C139%2C866%2C139%2C1920%2C0%2C1028%2C801%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=29&ifi=1&uci=1.elucdge8eas9&dtd=105" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.elucdge8eas9" data-load-complete="true"> |
