The adsorption type abrasive particle sensor adopts the latest scientific research technology, uses a new circuit design and model algorithm, fully considers the oil viscosity sensor in the online monitoring process, continuously records and evaluates the wear status of mechanical components in the oil, and plays an important monitoring role in early equipment failure wear. The probe can distinguish between small particles and micrometer level magnetic fragments, so that early equipment failures can be detected in a timely manner, improving the predictive maintenance data support of the equipment. Widely used in oil products such as steel, petrochemicals, shield tunneling, electricity, wind power, large equipment, OEM integration, etc.: hydraulic oil, turbine oil, diesel engine oil, insulation oil, transformer oil, etc.
