SDM-72/73

Product catalog summary

Overview: This document provides technical specifications and features of two portable devices designed to measure steel dust concentration in grease and lubricating oil, respectively. These devices are used for diagnosing the wear condition of mechanical components.

Specifications:

SDM-72: Measures steel dust concentration in grease using a magnetic balance type electromagnetic method. It has a measurement range of 0-5.00wt% with a resolution of 0.001wt%. The device requires approximately 0.8ml of sample and operates on 4 AA alkaline dry cells or an AC adaptor, with a battery life of up to 30 hours. It functions within a temperature range of 0 to 40℃ and weighs approximately 500g.
SDM-73: Measures steel dust concentration in lubricating oil using a similar electromagnetic induction method. It has a measurement range of 0-19999wt ppm with a resolution of 1wt ppm. The device requires 1.5ml of sample and shares the same power and operational specifications as the SDM-72.

Features:

Both models enable simple diagnosis and trend monitoring of wear conditions in bearings, gears, and other components by measuring steel dust concentration.
They offer straightforward operation by simply placing the sample in the device.

Applications:

SDM-72 is used for diagnosing wear conditions in greased bearings and gears, and as a pre-diagnosis tool for Ferrography and SOAP methods.
SDM-73 is used for monitoring wear conditions in bearings, gears, and cylinders, as well as for detecting steel dust contamination in hydraulic and grinding oils.

Accessories:

Standard accessories for SDM-72 include a carrying case, grease sampling spatula, and grease sample cases.
Standard accessories for SDM-73 include a carrying case, syringes, oil sampling nozzles, and a syringe holder.
Both models offer an optional AC adaptor.
