Portable Ferrous Debris Analyzer ASTM D8120

Portable Oil Ferrous Debris Tester is an important method for early warning and avoiding mechanical failures. It can detect worn parts at an early stage of wear, and serious losses can be avoided by replacing them. Existing abrasive particle monitoring methods all have some defects and deficiencies. For example, oil spectrometer is limited by carrying capacity and excitation energy, and cannot quantitatively monitor particles larger than 5 µm; the measurement results of ferrography are only relative coefficients rather than absolute concentrations. The use of the iron meter can directly measure the concentration of all ferromagnetic abrasive particles in the oil sample without processing the oil sample. The iron meter can analyze the content of iron abrasive particles in various samples of mineral oil, synthetic oil, hydraulic oil, gear oil and lubricating grease.

ASTM D8184 Oil Ferrous Debris Analyzer – PQ Index Tester

Standard: ASTM D8184

In terms of detection methods, the current iron content detection mainly includes atomic absorption method and atomic emission method. Although atomic absorption spectroscopy is accurate, it is slow and complex to operate. Atomic emission spectroscopy has been widely used, but it cannot effectively detect large wear particles (whether it is a rotary electrode or inductive ion coupling). Not sensitive to large particles can sometimes be fatal in monitoring and diagnosis, as particles with normal wear of the friction pair are generally less than 10 μ m, while metal particles larger than 15 μ m are generated due to abnormal wear.

ASTM D8184 PQ Index analyzer

As for the detection of iron particles, the remedy is to increase iron monitoring and use Ferrous Debris Monitor. The Ferrous Debris Monitor developed by our company is a measuring device based on the principle of electromagnetic induction. The measuring device is equipped with a sensitive electromagnetic coil. When the oil is placed in a magnetic field, the ferromagnetic abrasive particles in the oil will cause changes in the magnetic field intensity. The magnitude of the electromagnetic induction intensity of the coil is well correlated with the content of ferromagnetic abrasive particles. It can conveniently and quickly detect the content of ferromagnetic metal shavings in lubricating oil, hydraulic oil, and grease, thereby determining the mechanical wear condition.

Instrument Introduction

The KR-ONH6700 oxygen nitrogen hydrogen analyzer is a new generation element analysis instrument. It features a desktop integrated design, beautiful appearance, and easy operation.

The oxygen nitrogen hydrogen analyzer is an intelligent analytical instrument composed of a pulse furnace and a computer, with a pyroelectric sensor and a high-precision thermal conductivity detector as the core. The instrument is mainly used for the analysis of oxygen, nitrogen, and hydrogen content in ferrous metals, non-ferrous metals, rare earth metals, inorganic substances, ores, ceramics, and other materials in industries such as metallurgy, machinery, commodity inspection, scientific research, and chemical engineering.

Instrument principle

Oxygen, nitrogen, and hydrogen in metal and non-metallic solid materials are detected using the inert gas melting principle. In the determination of oxygen, nitrogen, and hydrogen, the weighed sample is placed in a graphite crucible and melted through high-temperature heating in a helium (argon gas can be used for single oxygen measurement) airflow. The oxygen in the sample reacts with the carbon in the graphite crucible to generate carbon monoxide (CO), and the nitrogen in the sample escapes in the form of nitrogen. These mixed gases are sent to the conversion furnace by helium gas, and carbon monoxide (CO) is converted into carbon dioxide (CO2). The nitrogen does not react. The mixed gas after passing through the conversion furnace is sent to an infrared detection cell, where carbon dioxide (CO2) (H2O) is detected. Then, after infrared detection, the carbon dioxide (CO2) and water in the mixed gas are adsorbed, and the remaining nitrogen and helium gas mixture is detected through a thermal conductivity detection cell. Quickly and accurately determine the oxygen, nitrogen, and hydrogen content in steel, cast iron, alloys, copper, zirconium, titanium, rare earth materials, and other inorganic substances.

Light source: The infrared light source uses efficient and long-lived precious metal miniature infrared luminescent bodies and gold-plated metal mirrors;

Constant temperature: The entire gas chamber is controlled at a constant temperature to ensure the constant temperature of the analysis gas and measurement accuracy. A temperature compensated semiconductor detector is used to ensure that the instrument is minimally affected by external factors and the baseline is very stable.

High precision detection system

The use of a highly sensitive thermal conductivity detection cell, continuously adjustable pool current, high-precision amplifier, and 24-bit A/D sampling card hardware ensure the determination of nitrogen content from ultra-low to large ranges. Adopting low drift, high accuracy, large range, high sensitivity thermal conductivity detector with low failure rate, strong reliability, and good stability.
