Iron and steel smelting and petroleum refining are important industries that are related to the national economy and people's livelihood. The process inspection of crude oil, semi-finished products and refined oil such as mining, processing, transportation and storage, as well as the storage and handover of gasoline and diesel oil all require oil inspection. At the same time, lubricating oil and hydraulic oil in a large number of mechanical equipment used in the above production process also need to be tested.    
    Through oil on-line monitoring systems, such as dielectric constant sensors, oil moisture sensors, granularity sensors, viscosity sensors, trace moisture sensors, leakage sensors, temperature and humidity sensors, etc., equipment reliability can be greatly improved, production efficiency can be improved, oil state can be detected in real time, oil change cost can be reduced, equipment wear state can be comprehensively mastered, equipment maintenance cost and shutdown risk can be reduced, and user benefits can be improved.     

     Diesel engines, main engine lubrication systems, fuel oil systems, steering engines and rotating machines of shipping and other transportation equipment are characterized by complex structure, high technical requirements for maintenance management, long maintenance period, humid environment and harsh operating conditions. In case of water inflow, abnormal viscosity change, etc., it is easy to cause safety accidents and huge losses.    
    By installing corresponding on-line monitoring sensors, such as dielectric constant sensors, oil moisture sensors, oil trace moisture sensors, oil quality sensors, viscosity sensors, metal wear particle sensors, etc., the reliability of the equipment can be greatly improved, the oil state can be detected in real time, the conversion from oil change on schedule to oil change according to quality can be realized, the oil change cost can be reduced, the failure early warning, the whole-life health management can be realized, the equipment maintenance cost and the shutdown risk can be reduced, and the user income can be improved.

      Construction machinery and equipment, such as armored vehicles, shield machines, cementing vehicles, drilling machines, transportation vehicles, hydraulic oil sources, oil filters, etc., are more vulnerable to internal lubricating oil and hydraulic oil pollution due to harsh operating environment.  
      Faults in the hydraulic system of construction machinery have an important relationship with external pollution, while less oil, severe working conditions and high-intensity operations make oil products more prone to decay and deterioration.          
      Such as moisture, viscosity, acid value and other indicators will deteriorate faster. Through oil on-line monitoring sensors, such as oil quality sensors, dielectric constant sensors, wear particle sensors, viscosity sensors, moisture sensors, etc., the reliability of the equipment can be greatly improved, the oil state can be detected in real time, the oil change cost can be reduced, the wear state of the equipment can be comprehensively mastered, the maintenance cost of the equipment can be reduced, the attendance rate of the equipment can be improved, and the income of users can be improved

     Oil monitoring of electric power equipment is an important parameter of equipment health management and is crucial to the safe operation of equipment. Generators in power plants, such as thermal generators, water turbines, steam turbines, wind turbines, transformers, reactors and pressure regulating switches in power transmission and transformation industries, use a large number of oils such as lubricating oil and hydraulic oil.    
    Through oil on-line monitoring systems, such as dielectric constant sensors, oil moisture sensors, granularity sensors, viscosity sensors, trace moisture sensors, leakage sensors, temperature and humidity sensors, etc., equipment reliability can be greatly improved, production efficiency can be improved, oil state can be detected in real time, oil change cost can be reduced, equipment wear state can be comprehensively mastered, equipment maintenance cost and shutdown risk can be reduced, and user benefits can be improved
