在线铁谱仪主要由探测器和分析器两部分组成。探测器安装在监测对象的润滑油循环系统的油路上，分析器则安装在控制室内。
On-line ferrography is mainly composed of detector and analyzer. The detector is installed on the oil circuit of the lubricating oil circulation system of the monitored object, and the analyzer is installed in the control room.
探测器由高梯度的磁场装置和沉淀管、流量控制器及一个表面感应电容传感器等构成。
The detector consists of a high gradient magnetic field device, a precipitation tube, a flow controller www.apsaLu.cn www.hunLiaoji.com.cn www.jnkeqing.cn www.hanyubw.cowww.ccdrc.cn www.bjguomei.cnand a surface induction capacitance sensor.
当探测器接通油路后，润滑油流经沉淀管时，油中磨粒在高梯度磁场的作用下沉积到沉淀管的内表面，表面感应电容传感器可以连续测出D L,Ds数值，分析器绘出相应大、小磨粒浓度及磨粒尺寸分布状况。
When the detector is connected to the oil circuit and the lubricating oil flows through the precipitation tube, the abrasive particles in the oil deposit on the inner surface of the precipitation tube under the action of high gradient magnetic field. The surface induction capacitance sensor can continuously measure the values of D L and Ds, and the analyzer can draw the corresponding distribution of large and small abrasive particles concentration and size.
