菲尼克斯传感器光电式传感器是基于光电效应的传感器,在受到可见光照射后即产生光电效应,将光信号转换成电信号输出。光电传感器一般由光源、光学通路和光电元件三部分组成。它除能测量光强之外,还能利用光线的透射、遮挡、反射、干涉等测量多种物理量,如尺寸、位移、速度、温度等,因而是一种应用极广泛的重要敏感器件。其特点价格低廉,输出电流大,受温度的影响小,抗干扰能力强,可靠性高。光敏二极管和光敏晶体管灵敏度高,响应时间快,但它受温度影响比较大,受光面小,不同型号的管子对光谱响应有很大不同。 菲尼克斯传感器光电传感器由其背部元器件的不同而使各细类使用限制条件有所不同。在采用何种光电传感器的时候应考虑其具体的使用环境。例如光纤式光电传感器的使用限制:避免在水中、降雨及室外使用;安装在以下场所时,会引|起误动作和故障;避免产生腐蚀性气体的场所和阳光直接照射的场所,有震动冲击的场所和湿度高,可能会结露的场所。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?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A8%2C2%3A8%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=1614047285363&bpp=10&bdt=73&idt=170&shv=r20210217&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff-22ed306a0ec40076%3AT%3D1602729171%3ART%3D1602729171%3AS%3DALNI_MbBh5yg2uKd0UtH0u1Ylcdyq42wTg&nras=1&correlator=5718204163950&frm=23&ife=1&pv=2&ga_vid=564100907.1614047286&ga_sid=1614047286&ga_hid=703697962&ga_fc=0&nhd=1&u_tz=480&u_his=7&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=831&bih=584&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21068084%2C21068769%2C21068893%2C21068946%2C21069109&oid=3&pvsid=1401749153622472&pem=217&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1664&brdim=604%2C0%2C604%2C0%2C1920%2C0%2C1312%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=9228&bc=31&ifi=1&uci=1.iebcll3220w9&fsb=1&dtd=206" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.iebcll3220w9" data-load-complete="true"> |
