直读式铁谱仪广泛地应用于各类机器系统的磨损监控和润滑油油品评定，也可用来进行磨擦状态及磨损机理的研究，因此，它是实现机器工况监测、设备故障定位和进行微粒磨擦学研究的重要仪器
Direct-reading ferrography is widely used in wear monitoring and lubricating oil evaluation of various machine systems. It can also be used for the study of friction state and wear mechanism. Therefore, it is an important instrument for realizing machine condition monitoring, equipment fault location and particle friction research.
直读式铁谱仪是由主机与趋势分析软件组成，其原理是将磨粒有序沉积在沉积管内，利用光电转换原理，测出表征油液样品中大磨粒（大于5μm）浓度和小磨粒（1～2μm）浓度的Dl和Ds值。
Direct-reading ferrography is composed of host computer and trend analysis software. Its principle is that zhujian.37ix.com.cnshidiaocs.37ix.com.cnshidiaorw.37ix.com.cn suliaotp.37ix.com.cnsujiaopvc.37ix.com.cnsujiaodb.37ix.com.cnabrasive particles are deposited orderly in the deposition tube. Using photoelectric conversion principle, the Dl and Ds values representing the concentration of large abrasive particles (greater than 5 micron) and small abrasive particles (1-2 micron) in oil samples are measured.
