COSMOS SDM-72, SDM-73 measure the amount of steel dust in oil

Producer: NEW COSMOS

Category: Substance concentration measuring device Tag: steel dust meter

The NEW COSMOS SDM-72/SDM-73 devices can diagnose bearing condition, even long before wear-induced vibration is detectable, by measuring the amount of steel dust in the grease/oil surrounding the bearing.
Feature
• Best suited for diagnosing low speed rotating machinery and variable speed rotating machinery that is difficult to diagnose with vibration indicators
• Battery operated and convenient to carry or use on site
• Simple operation without the need for specialized knowledge
• Equipped with auto-zero function
• Diagnosis can be made with only a small amount of grease/oil sample
Measurement principle
The measurement principle of the magnetic balance electromagnetic induction method is shown in the illustration below, the magnetic circuit sensor consists of an excitation coil connected to both sides of the detection coil, the magnetic field generated by both excitation coils is covered in the vicinity of the central detection coil.
Normally, the central detection coil does not generate an induced voltage, on the other hand, when the sampled oil containing iron particles is introduced into the excitation coil, the magnetic field is offset by the change in magnetic permeability, and an induced voltage is generated in the detection coil. The induced voltage can measure the concentration of iron particles in the sampled oil.

NEW COSMOS Japan

Portable steel dust meter

to check the wear condition of bearings in ultra-low to high speed rotating machinery

Model: SDM-72 /SDM-73

With the SDM-72 SDM-73 you are able to diagnose the bearing condition, even long before wear-induced vibration becomes detectable, by measuring the amount of steel dust in oil around the bearing.

Within 3 seconds the meter gives you a readout of the ferro magnetics particles in the oil in parts per million ppm. No need to send your sample to a laboratory for analyzes any longer. You now get on the spot direct measurement.

The meter can be used in any rotating equipment application such as robots, wind turbines, elevators etc. etc. Preventive maintenance is key for increase in uptime of your equipment.

Features

Measuring Principle
The measuring principle of the magnetic balance electromagnetic induction method is shown in the illustration below, the magnetic circuit sensor is composed of an exciter coil connected to the both sides of the detection coil, the magnetic field generated by both exciter coils are blanketed in the vicinity of the center detection coil.
Normally, the center detection coil does not generate an induction voltage, on the other hand when the sampled oil containing iron particles is inserted into the exciter coil, the magnetic field is offset by the magnetic permeability variation, and an induction voltage is generated in the detection coil The induction voltage can measure the concentration of the iron particles in the sampled oil.
