KLD-Z-X Online Oil Contamination Monitor

Product Introduction
The KLD-Z-X Online Oil Contamination Monitor is a compact, intelligent instrument designed for real-time monitoring of particle contamination in hydraulic and lubricating oil systems. Using laser sensing technology, it provides rapid oil cleanliness measurements, with results available in approximately 6 seconds.
Continuous oil particle monitoring helps maintenance teams identify contamination early, reduce component wear, minimize unplanned downtime, and extend hydraulic equipment service life. With RS485/RS232 communication and optional display of ISO and NAS cleanliness ratings, the KLD-Z-X is suitable for industrial oil condition monitoring and predictive maintenance.

Performance Features
• Laser particle detection: Provides accurate monitoring of particulate contamination in oil.
• Fast measurement: Delivers test results in approximately 6 seconds.
• Online real-time monitoring: Supports continuous observation of hydraulic and lubricating oil cleanliness.
• ISO/NAS cleanliness ratings: Optional simultaneous color display of standardized contamination levels.
• Compact and lightweight: Weighs only 538 g with the display, simplifying installation and retrofitting.
• Low sampling flow: The small oil flow through the instrument minimizes interference with normal hydraulic system operation.
• Multiple communication interfaces: RS485 and RS232 outputs support data transfer to a PC or external display.
• Optional alarm and printing: Alarm functions and online printing are available as optional configurations.
• Industrial operating range: Designed for working temperatures from -20°C to 60°C and media temperatures from -20°C to 80°C.

Working Principle
The KLD-Z-X uses a laser sensor to detect particles passing through the oil sampling channel. As contaminated oil flows through the sensing area, particles produce optical signals that are processed by the instrument to determine contamination levels. The resulting data can be used to assess oil cleanliness and, with the appropriate configuration, display ISO or NAS cleanliness ratings.
Measurement results can be transmitted through RS485 or RS232 to a PC or external display. Optional alarm and printing functions support equipment monitoring and maintenance workflows.
