Online Oil Particle Counter

Product Introduction

The HD-YZ20 (horizontal type) On-Line Particle Counter adopts the light-blocking (light-extinction) counting principle specified by the International Hydraulic Standards Committee and is an oil contamination grade detection device specially used for on-site on-line measurement. It has the advantages of small size, light weight, fast detection speed, high accuracy and good repeatability, and can work under extremely harsh conditions such as high temperature and high pressure. It is suitable for engine oil, gear oil, transformer oil (i.e. insulating oil), hydraulic oil, lubricating oil, synthetic oil, water-based fluids (water-based hydraulic oil, water-glycol, etc.), alcohols, ketones and all other light-transmitting solvents, and can be widely used in aerospace, petrochemical, transportation and ports, iron and steel metallurgy, 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.
