VRT-2振动速度传感器

日期:2019-07-02浏览:84次

一、产品概述:

振动速度传感器主要安装在各种旋转机械装置的轴承盖上(如汽轮机、压缩机、风机和泵等)的传感器。它主要由磁路系统、线圈组件、弹簧阻尼等部分组成。在传感器壳体中刚性地固定有两个线圈组件,磁钢用弹簧悬挂于壳体。当传感器在工作频率范围内工作时,线圈与磁钢产生相对运动,线圈切割磁力线,产生感应电动势(感应电压),该电压正比于机壳的振动速度提供信号输送给监测仪表,用来对机械故障进行预测和报警。传感器具有工作时不需要供给电源、安装方便,耐高温等特点。

二、技术参数:

1.  灵 敏 度:  20mV/mm/s±5%                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

2.  频率响应: 10~ 1000 Hz

3.  测量范围: 2mm (峰-峰值)

4.  最大加速度:10g

5.  使用环境: -30℃~100℃(相对湿度:≤90%)

6.  测量方向: 垂直或水平(详见标签)

7.  外形尺寸: φ33×75mm

8.  重    量:  约240g

9.  安装螺纹: M10*1.5*10

三、安装方式:

垂直或水平安装在被测点上,将传感器底部螺钉固定在被测壳体上,然后将传感器拧紧即可。并定期检查不得有松动。

四、注意事项:

传感器应防止剧烈碰幢和敲打,运输过程和贮存时应置于专用包装盒内
