Online Oil Particle Counter

Product Introduction

The HD-YZ50 On-Line Oil Particle Counter adopts the light-blocking (light-extinction) counting principle specified by the International Hydraulic Standards Committee and is developed in accordance with GB/T 18854-2002 (ISO 11171-1999) and other national and international standards, dedicated to the grade detection of contaminating particles in liquids. It provides fast, accurate, reliable and repeatable detection results. It is simple and convenient to operate and suitable for on-line monitoring of various oil systems. Two (or more) slave units can also be connected to the same host or platform for comparison tests, with simple operation and flexible combinations. It can be widely used in aviation, aerospace, electric power, petroleum, chemical engineering, transportation, ports, metallurgy, water treatment, machinery, automobile manufacturing and other fields.

Main Features

• Adopts the light-blocking (light-extinction) counting principle specified by the International Hydraulic Standards Committee.
• High-precision laser sensor with wide test range, stable performance, low noise and high resolution.
• Uses a high-precision bidirectional plunger pump with stable injection speed and high sampling accuracy (standard model).
• A built-in pressure-reducing device can be used for on-line high-pressure testing.
• Built-in more than ten common standards including GJB-420A, GJB-420B, NAS1638, GB/T14039, ISO4406, SAE4059cpc, SAE4059F, SAE749D, GOST17216, QC/T29104, JB/T9737, DLT432 and HH005-2018; one test can give the data results under all built-in standards.
• Built-in data analysis system automatically determines the sample grade according to the standard, continuously monitors the system with an alarm function, and can separately set grade alarms for each standard and size alarms for each channel.
• Built-in multiple calibration curves compatible with all common domestic and international standards for calibration.
• Realizes continuous automatic on-line detection with arbitrarily settable detection interval.
• Baud rate can be set.
• Chinese and English dual systems, freely switchable by the user.
• Different accounts and passwords can be added and permissions set.
• Equipped with RS232, RS485 and USB interfaces, and can be connected to a computer or laboratory platform or to an industrial fieldbus.
• Data storage and printing functions for convenient data organization and archiving.
• Can be used as a stand-alone unit, can be connected upstream and downstream to calculate the filtration rate, and multiple units can be interconnected for unified remote host monitoring with curve generation, historical query and data export, with various combinations and strong application expandability.
• High-strength metal housing suitable for harsh on-site environments.
• Instrument functions and dimensions can be customized in batches according to customer requirements.
