Description

technical field [0001] The invention relates to a full-fluid flow metal abrasive sensor, in particular to a differential oil abrasive online sensor testing system, which belongs to the technical field of measurement and control equipment. Background technique [0002] Oil is compared to the blood of mechanical equipment, which contains a wealth of information. The monitoring of abrasive particles in the oil can be used to know the operating status of mechanical equipment, which is of great significance for early failure prediction of equipment. The traditional oil monitoring technology mainly adopts off-line methods, such as particle counting method, spectroscopic method, etc., which can realize the off-line monitoring of oil products and solid impurities in oil. It is labor-intensive, time-consuming, costly, and the return of the measurement results is delayed, so the application in many application fields is greatly limited. In view of this, online monitoring technology h...

Problems solved by technology

The traditional oil monitoring technology mainly adopts off-line methods, such as particle counting method, spectroscopic method, etc., which can realize the off-line monitoring of oil products and solid impurities in oil. Laborious, time-consuming, high cost, and the return of measurement results are delayed, so the application in many application fields is greatly limited

In view of this, online monitoring technology has become one of the research directions of those skilled in the art. According to the principle, it can be divided into four categories: optical type, electromagnetic type, conductive type and ultrasonic type, but they are still in the stage of theoretical research.
