Working Principle of Portable Oil Particle Counter

The portable oil particle counter operates based on the optical obstruction (shading) method, which is defined by international standards such as the International Hydraulic Standards Committee (ISO). The core working principle involves laser light scattering. Here's a detailed breakdown of the process:

1. Laser Scanning: The oil sample is introduced into the counter, where it is illuminated by a laser beam.
2. Particle Interaction: As the laser light passes through the oil sample, it interacts with any particles present. The particles cause the laser light to scatter.
3. Light Scattering: The scattered light intensity is directly proportional to the size of the particle. Larger particles scatter light with greater intensity, while smaller particles scatter light less intensively.
4. Data Analysis: By analyzing the intensity and pattern of the scattered light, the counter calculates the number, size distribution, and concentration of particles in the oil sample.

In this way, the portable oil particle counter can accurately determine both the size and quantity of particles present in the oil, providing a comprehensive understanding of the oil’s contamination level.

Application Scenario Analysis

The portable oil particle counter is an essential tool in various industries for maintaining the health and longevity of machinery and systems that depend on oil as a lubricant or coolant. Here’s an overview of its application across different fields:
