STEEL DUST METER SDM-72 / SDM-73 Be sure; be safe. Model STEEL DUST METER Portable steel dust meterto check the wear condition of bearings in ultra-low to high speed rotating machinery Measuring Principle External Dimensic^P 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. Sampled grease or sampled oil New cosmos ececTRic coltd . NEW COSMOS ELECTRIC CO.f LTD.

STEEL DUST METER SDM-72 / SDM-73 STEEL DUST METER SDM-72 / SDM-73 SDM-72/SDM-73 units can diagnose the bearing condition, even long before wear-induced vibration becomes detectable, by measuring the amount of steel dust in the grease/oil around the bearing. Case Study Features • Best suited to diagnose low-speed rotation machinery and variable-speed rotating machinery which are hard to be diagnosed by vibration indicators • Battery-operated and convenient to carry or use on-site • Simple operation without requiring special knowledge • Equipped with auto-zero function • Able to diagnose with only...
