Compact MR measuring system - Detection of magnetic nanoparticles in lubricants
An invention with a prototype for the detection of the concentration and agglomeration of magnetic nanoparticles in cordage at the site of their use.
Easy sample preparation,
Not time-consuming cleaning after measurement,
Continuous measurements possible
In order to ensure a safe and permanent operation of machines and equipments such as elevators, load cranes, ski lifts etc., u.a. the lubricant quality is monitored. It is important to determine the particle concentrations of magnetic components in the lubricant. This invention is therefore interesting for "critical assets" - infrastructure facilities for which a secure and continuous operation is a deciding factor for success.
The "point-of-inspection system" is a detection device that allows the concentration and size of magnetizable particles in lubricants such as oil and hydraulic fluids to be continuously determined. Since the particles are not separated from the sample medium as usual, sampling, sample preparation and sample pretreatment are eliminated. Also, a cleaning of the measuring device after each measurement is not required. The principle: The particle-loaded sample moves through a magnetic field, which is generated for example by a coil.
