倍加福传感器的定义及组成传感器的概念来自“感觉(sensor)” 一词,人们为了研究自然现象,仅仅依靠人的五官获取外界信息是远远不够的,于是发明了能代替或补充人五官功能的传感器,工程上也将传感器称为“变换器"。能感受规定的被测量并按照一定规律转换成可用输出信号的器件或装置是传感器的主要定义。 一个指定的传感器只能感受规定的被测量,即传感器对规定的物理量具有Z大的灵敏度和Z好的选择性。例如温度传感器只能用于测温,所以不希望它同时被其它物理量的影响;从传感器的输出端来看传感器的输出信号为“可用信号”,这里所谓的“可用信号”是指便于处理、传输的信号,如电信号、光信号。未来的“可用信号”或许是较为实用的其它信号形式。传感器的输入输出关系具有“一定规律”,即传感器的输入与输出不仅是相关的,而且可以用确定的数学模型来描述,也就是具有确定规律的静态特性和动态特性。http://www.amypf.com/027-87263542手机:18372021864LED">ABSolute;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" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=3%3A32%2C4%3A32%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=1646364296891&bpp=2&bdt=288&idt=27&shv=r20220302&mjsv=m202202280101&ptt=9&saldr=aa&cookie=ID%3D2c186cce80d69fb1-221c8408a0ce006c%3AT%3D1636508022%3ART%3D1636508022%3AS%3DALNI_Mbu0HZjDtEO7dny0NgdC9Kvxw3uwg&nras=1&correlator=812927879756&frm=23&ife=1&pv=2&ga_vid=1326492890.1646364297&ga_sid=1646364297&ga_hid=642423232&ga_fc=0&nhd=1&u_tz=480&u_his=5&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_sd=1&DMC=4&adx=-12245933&ady=-12245933&biw=1132&bih=945&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42531398%2C44750773%2C44756896%2C31064019&oid=2&pvsid=3861903622237438&pem=217&tmod=586497464&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&eae=2&fc=1664&brdim=609%2C0%2C609%2C0%2C1920%2C0%2C1180%2C1082%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.2hsfwnw6susj&fsb=1&dtd=55" data-google-container-id="1.2hsfwnw6susj" data-load-complete="true"> |
