For a limited time, until 31st December 2017, FLUKE says it is offering a 16% saving when purchasing a FLUKE-805 FC/805 ES bundle consisting of a Fluke 805 FC Vibration Meter, together with a Fluke 805/ES external vibration sensor - www.fluke.co.uk/805, saving is based on the cost of the items if purchased separately.
The natural frequencies of the piezoelectric cantilever are closer to the external vibration frequency, and more electricity can be generated.
[6], and the major effort in building a high quality STM has been to improve the design of its head structure so as to obtain better stability, immunity to external vibration, and tip positioning precision, which are all vital to atomic resolution or tunneling current spectrum quality and are still far from being satisfactory even today, especially under harsh vibration and sound environments.
Hence, we can conclude that the external vibration is attenuated significantly through the transmission of the spacecraft multifunctional structure.
