Hydraulic system sudden failures, abnormal gearbox wear, diesel generator sets shutting down midway – these equipment “breakdown” scenarios often stem from invisible metal debris in the lubrication system. Acting like “invisible grit,” they quietly accelerate component wear, ultimately leading to shutdowns, production halts, and even incurring high maintenance costs.
The ZH30 Oil Metal Debris Sensor is designed specifically to safeguard lubrication systems, building a protective barrier for equipment through intelligent monitoring.

Core Advantages: Precise Monitoring, Early Warning of Hazards
- Captures all ferromagnetic debris: Utilizes dual reverse electromagnetic coils + magnetic field compensation algorithm to continuously adsorb metal particles passing the probe. Covers both fine particles (<500μm) and coarse particles (>500μm), with resolution as low as 0.1%, ensuring no wear hazard goes undetected.
- Self-cleaning cycle for ease of mind: Automatically releases adsorbed particles upon saturation, requiring no manual cleaning. Enables 24/7 uninterrupted monitoring, reducing maintenance workload.
- Key data visualized: Uses dual indicators – Metal Debris Saturation (MDS) and Time Lag Between Self-Cleaning Cycles (TLAG) – to provide real-time feedback on equipment wear status. Allows for early judgment and intervention in accelerating wear trends.
Practical Highlights: Wide Compatibility, User-Friendly
- ZH30 Oil Metal Debris Sensor: Equip your lubrication system with a “safety radar,” making potential equipment hazards visible in advance.
- 70% of mechanical failures originate from wear, and metal debris in the oil circuit are the “sentinels” signaling equipment wear – invisible ferromagnetic and non-ferromagnetic particles circulating in the oil, quietly scraping components, accelerating wear, and ultimately causing shutdowns, production stops, and even irreversible equipment damage.
- The key to protecting lubrication system safety lies in accurately capturing these “invisible killers.” The ZH30 Oil Metal Debris Sensor uses robust technology to fortify equipment safety defenses, leaving no hiding place for wear hazards.
Core Advantages: Precise Monitoring, Ensuring Safety
- Detects both material types: Not only accurately detects ferromagnetic particles starting from 40μm, but also covers non-ferromagnetic particles starting from 150μm. Five particle size grades with a total detection rate exceeding 80%, providing comprehensive wear status awareness.
- Highly sensitive four-coil technology: Innovative coil coupling structure enhances signal stability, significantly reduces interference, improves signal-to-noise ratio, and allows precise capture of even tiny particles. Provides early warning of wear trends before failures occur.
- Quantified, traceable data: Features RS485 MODBUS RTU digital output, with an adjustable counting cycle of 300-3600S. Reports debris count and size distribution in real-time, providing data-driven equipment health status and informed maintenance decisions.
Practical Highlights: Wide Compatibility, Effortless Use
- Compatible with multiple scenarios and oils: Suitable for hydraulic systems, gearboxes, diesel generator sets, etc. Works with various oil types including hydraulic oil, gear oil, turbine oil, etc., eliminating the need for separate model selection for different equipment.
- Zero burden on installation and operation: M14*1.5 threaded interface + standard 2-meter cable. Ready for direct integration into the oil circuit. IP65 protection rating paired with 304 stainless steel housing ensures weather resistance, durability, and suitability for complex working conditions.
- Low consumption, stable, and reliable: Operating current <100mA, low energy consumption without extra costs. Permissible oil pressure ≤2MPa, fluid temperature -20~80℃, ensuring stable, long-term operation without faults.

Lubrication system safety is the baseline for continuous equipment operation. The ZH30 Oil Metal Debris Sensor replaces experiential judgment with precise monitoring, preventing wear failures from the source, enabling more stable equipment operation, easier maintenance, and greater safety assurance for your assets!
