菲尼克斯传感器电感式传感器可分为:变磁阻式(自感式)、变压器式和涡流式(互感式)。压电式传感器是以某些介质的压电效应作为工作基础的。压电效应是指对某些电介质沿一定方向施以外力使其变形时,其内部将产生极化现象而使其表面出现电荷集聚的现象,也成为正压电效应。逆压电效应是指:当在片状压电材料的两个电极面上加交流电压,那么电压片将产生机械振动, 即压电片在电极方向上产生伸缩变形,压电材料的这种现象称为电致伸缩效应。 菲尼克斯传感器压电式传感器结构简单、体积小、重量轻、工作频带宽、 灵敏度高、信噪比高、工作可靠、测量范围广。利用电磁感应的磁电感应式传感器和利用霍尔效应的霍尔式传感器,都称为磁敏式传感器。传感器的热电动势一部分是由两种导体接触电动势构成,另一部分是由单一导体的温差电动势产生。一般情况下,热电偶的冷端温度补偿方法有导线法、冷端恒温法、冷端温度校正法和自动补偿法。http://www.amy07.com/027-87263542手机:18372021864ABSolute;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%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=29.0.0&pra=5&wgl=1&dt=1619337581322&bpp=5&bdt=137&idt=30&shv=r20210422&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff-22ed306a0ec40076%3AT%3D1602729171%3ART%3D1602729171%3AS%3DALNI_MbBh5yg2uKd0UtH0u1Ylcdyq42wTg&nras=1&correlator=5488377442802&frm=23&ife=1&pv=2&ga_vid=693630677.1619337581&ga_sid=1619337581&ga_hid=2065649498&ga_fc=0&nhd=1&u_tz=480&u_his=11&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=14&u_nmime=31&adx=-12245933&ady=-12245933&biw=1114&bih=834&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31060840&oid=3&pvsid=1199934359202538&pem=217&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1664&brdim=709%2C0%2C709%2C0%2C1920%2C0%2C1218%2C1013%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=31&ifi=1&uci=1.i1czzhy6butc&fsb=1&dtd=69" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.i1czzhy6butc" data-load-complete="true"> |
