Product Features
The MMS6220 offers a set of reliable product characteristics. Key MMS6220 product characteristics include its self-generating nature, requiring no external power supply, which simplifies installation and enhances reliability in remote locations. The robust stainless-steel housing of the MMS6220 ensures excellent durability in harsh conditions, including exposure to moisture and chemicals. Furthermore, the wide frequency response of the MMS6220 makes it highly effective for monitoring vibration on a variety of machinery, from slow-speed turbines to higher-speed pumps and fans.

0301068B Comparison

When comparing the MMS6220 to other models, its primary advantage is its passive operation, unlike powered transducers like the MMS6110. This makes the MMS6220 a direct replacement for many legacy velocity sensors without requiring wiring changes. However, compared to more modern IEPE accelerometers, the MMS6220 has a lower frequency response and cannot measure very high frequencies or low-level vibrations as effectively. Therefore, while the MMS6220 is an ideal replacement for similar passive velocity sensors in standard machinery monitoring, it is not a direct substitute for high-frequency accelerometers used in detailed analysis. The MMS6220 excels in applications where simplicity and reliability are paramount.

0301068Bapplication cases

The MMS6220 sees extensive use in engineering projects globally. A significant application for the MMS6220 is on critical turbomachinery in power plants, including coal, gas, and nuclear facilities, where it monitors bearing vibration for early fault detection. In the oil and gas industry, the MMS6220 is deployed on large compressors and pumps on offshore platforms and pipelines, valued for its ruggedness and lack of external power requirements. Furthermore, the reliability of the MMS6220 makes it a common choice for monitoring fans, blowers, and other rotating equipment in pulp and paper mills and metal processing plants worldwide. The widespread adoption of the MMS6220 is a testament to its proven performance in demanding industrial settings.
