subject: How Magnetometers Can Help Determine The Condition Of Moving Parts [print this page] Magnetometers are machines used to check the metal wear within oil and grease samples. A sample test can be performed to see what is present in the sample, whether it is of a concerning nature and even what could be causing the deposit. Microscopic metallic particles often show up in grease or oil on industrial machines as lubrication deteriorates, allowing for increased contact between parts. When these parts become more apparent or evolve in shape, this can indicate that there is a malfunction along the line.
Examining samples can be done using two main types of technology. The first is through regular testing with an on-site lab, which is purpose built for easy testing of collected samples. The compact look of most magnetometers is misleading, as they can handle complex sample analysis in as little as 20 seconds. All this entails is the insertion of the sample into the designated space. The second is done by using on-line sensors which give engineers instant readings without having to take samples. There are motives to use both of these methods in a production line.
Whether an advantage or disadvantage, cost frequently features in the decision making for buying a ferrography machine. Getting the right price for the best equipment can be crucial, which is why some companies would rather choose the more affordable option of the on-site labs. A shortcoming of this is the delay between samples that could mean missing a vital reading and risking damage to machinery. When time is of the essence in business, the most desired option is the real-time sensor.
Testing samples in this manner is about more than routine inspection of machinery. When wear and tear finally obstructs the normal operations of a machine, this can do more than temporarily bring everything to a halt. Magnetometers help to detect alterations in samples that indicate serious damage could occur. Losing vital lubrication or function in one part of a system can be enough to put a whole section out of commission. When a company has spent hundreds of thousands on their machinery, and relies on it working to earn back the costs, a malfunction is a big concern.
Testing samples on magnetometers is just one way to look for indications of machine damage. Vibrations, emissions, water presence and changes in the texture of grease and oil all suggest the health of the machine. For this reason, a business should assess the most important parts of their production line and research all of the options available to them.
