PQM-10 Online Lubricating Oil Wear Particle Sensor
Product Introduction
The PQM-10 Online Lubricating Oil Wear Particle Sensor is an industry-leading intelligent sensor designed for continuous, full-flow monitoring of metallic wear debris in lubricating oil. It provides reliable early warning of abnormal wear in critical mechanical components such as gearboxes, bearings, turbines, hydraulic equipment, and other rotating machinery.
Using advanced electromagnetic detection technology, the PQM-10 accurately detects both ferrous and non-ferrous wear particles flowing through the lubrication system. It measures particle size, quantity, mass, generation rate, and cumulative trends, enabling predictive maintenance, equipment health assessment, and remaining service life estimation. The sensor effectively suppresses false alarms caused by air bubbles and water bubbles, ensuring highly reliable monitoring in demanding industrial environments.

Key Features
• Continuous 100% full-flow online monitoring of lubricating oil
• Detects both ferrous and non-ferrous wear particles
• Early detection of abnormal gearbox, bearing, and transmission wear
• Monitors particle quantity, size, mass, generation rate, and cumulative trends
• Intelligent trend analysis for predictive maintenance
• Eliminates false alarms caused by air bubbles and water contamination
• Rugged industrial construction for harsh operating environments
• Supports direct installation in the main oil circuit or bypass installation
• Digital communication output for seamless integration with monitoring systems
• Improves equipment reliability while reducing maintenance costs and unexpected downtime

Working Principle
The PQM-10 operates using a high-sensitivity electromagnetic sensing principle. As lubricating oil passes through the sensor's magnetic detection zone, metallic wear particles disturb the magnetic flux generated within the sensing field. These disturbances are precisely measured and converted into particle information.
The sensor distinguishes ferrous and non-ferrous particles by analyzing the opposite phase characteristics of their electromagnetic signals. Signal amplitude is used to determine particle size, while advanced algorithms calculate particle count, mass, appearance rate, and long-term wear trends. Bubble suppression technology minimizes false alarms caused by air or water bubbles, ensuring stable and reliable monitoring.
