Online Particle Counter ARL-OPC-500

The Online Particle Counter ARL-OPC-500 online particle counter is a compact fluid particle counter that also functions as a contamination sensor or cleanliness sensor. It is designed based on the light obstruction (light-blocking) principle. The device can be installed and operated in real time to measure the contamination levels of various liquids such as hydraulic oils and lubricants. It is suitable for monitoring oil condition in industrial equipment used in hydraulics, lubrication systems, and more. This makes it a reliable tool for preventive maintenance and advanced manufacturing applications.

Key Features:

High-precision laser and photoelectric transceiver components ensure measurement accuracy.
Suitable for various fluids, real-time monitoring of cleanliness levels 24/7.
Ensures safe operation of hydraulic and lubrication systems, preventing excessive contamination.
Optional online detection of oil moisture saturation level for enhanced diagnostics.
Stores up to 3000 test records.
Compact, robust, durable, intelligent, and easy to integrate.
Built-in flow estimation function ensures measurement accuracy.
Detects abnormal contamination and wear to safeguard asset operation.
Continuous and interval measurement modes are freely configurable.
Fast response with adjustable accumulation and measurement cycles.
Excellent chemical resistance and high-pressure tolerance.
Dual isolation for EMC and explosion protection, ensuring long-term stable operation in harsh environments.
No moving parts or consumables, designed for a ten-year service life.
