概述

990振动变送器主要是离心式空气压缩机、小型水泵、电机或风机的原始设备制造商(OEM) 为了将简单的振动信号，按照比例变送成4至20 mA信号提供给设备的控制系统。该变送器是一款两线制、环型供电的设备，可接受本公司3300 NSv*接近探头的输入信号及其匹配的延长电缆(有5米和7米的系统长度可供选择)。变送器可将信号调整为相应的振动峰值单位，并将此值按比例变成4至20mA的工业标准输入信号提供给控制系统1，以便机组的保护、报警和逻辑控制。990变送器具备以下显著特点:集成的前置器单元，不需要外部装置。非隔离的“PROX OUT"和"COM"端子加上同轴连接器可提供动态的振动和间隙电压信号输出，以便进行故障诊断?。零点电位器和量程电位器支持回路调节，相互间不会制约。采用函数发生器方式作为输人，在测试输入端可快速验证回路信号输出。-上电抑制电路可消除由于线路瞬变电压信号而导致的错误。非正常/信号故障电路可防止由于接近探头发生故障或连接松动而导致的高输出或假警报。选择DIN导轨压板或隔板固定螺钉作为标准选配件，可简化安装。密封结构适用于高湿度(高达100%结露) 环境。与3300 NSv接近探头兼容，传感器可安装在最下间隙、典型式的离心式空气压缩机狭小区域中。本特利990-04-50-01-CN 本特利330103-00-03-10-02-05 本特利330105-02-12-10-02-05 本特利3500/25-01-01-00本特利131151-01 本特利16925-03 本特利16710-03 本特利133396-01    本特利177230-01-02-CN本特利177230-01-01-CN  本特利卡件3500/25-01-01-00 本特利卡件131151-01本特利40113-02 本特利330505-02-02-02 本特利330505-01-02-02 本特利330180-51-00本特利330130-040-00-00 本特利40180-02 本特利330130-045-00-00 本特利330130-040-02-00 本特利40113-02本特利3500/05-02-04-00-00-01  本特利3500/15-05-05-00  本特利3500/42-01-00  本特利3500/32-01-00   本特利3500/94-03- 00-00  本特利330180-51-00 本特利330130-040-00-00 本特利40180-02 本特利330130-045-00-00 本特利330130-040-02-00本特利330881-16-11-088-06-02本特利330780-90-00 本特利330180-90-00 本特利330850-90-CN 本特利330103-00-06-10-02-00 本特利330703-000-060-10-02-00 PARent;">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-pointer-lock 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&dt=1595829119364&bpp=16&bdt=460&idt=440&shv=r20200723&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Ddb34b3484dfc4c41%3AT%3D1588921024%3AS%3DALNI_MaY7lX_nxkLXJGm06pq9JGcv5RA4w&nras=1&correlator=5508866601530&frm=23&ife=1&pv=1&ga_vid=1817405261.1595829120&ga_sid=1595829120&ga_hid=70848186&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=50&u_java=0&u_h=900&u_w=1440&u_ah=860&u_aw=1440&u_cd=24&u_nplug=27&u_nmime=54&adx=-12245933&ady=-12245933&biw=1423&bih=700&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=3&pvsid=2023662774652872&pem=257&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1920&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=0.3p7r0mrhx8dj&fsb=1&dtd=518" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.3p7r0mrhx8dj" data-load-complete="true">
