(MENAFN- PR Newswire) SUZUKA, Japan, Jan. 25, 2023 /PRNewswire/ -- NSXe Co. LTD., a Japan-based company providing services for mechanical
equipment installation and maintenance, newly released a Wi-Fi vibration
sensor, 'conanair,' in the U.S. in January 2023. NSXe's Wi-Fi sensor enables
users to detect bearing damage at a much lower cost than before. The company
has started its digital marketing through online database Engineering360.

Wi-Fi vibration sensor 'conanair' and 'Under Sampling' technology
Conventionally, expensive and high-resolution vibration sensors were thought to
be required to capture the impact vibration caused by bearing damage. It has
also been believed that inexpensive digital output sensors with low-sampling
frequency cannot measure such vibrations, or that high-frequency impact
vibrations create a large fold-back noise that impedes measurement.
When a bearing is damaged, high-frequency impact vibrations are generated, and
the bearing damage can be diagnosed by checking the envelope (change in
amplitude) and the interval between the vibrations. (This is an established
technology with a track record of more than half a century.) The technology
called 'Under Sampling' is mainly used in wireless communication systems that
must handle high-frequency signals. It makes active use of aliasing noise to
handle high-frequency signals even at low sampling frequencies.
Using a general-purpose vibration sensor that is capable of 'Under Sampling,'
NSXe confirmed the impact vibration intervals necessary for bearing diagnosis,
and it succeeded in manufacturing the inexpensive, low-resolution 'conanair.'
It can capture vibrations, enabling diagnosis of bearing fault.
Affordable Wi-Fi vibration sensor 'conanair'
Just as a doctor would listen to a patient's heart during physical examination,
the main purpose of 'conanair' is to perform health checks on machinery and
equipment. Until now, high-performance, expensive vibration sensors have been
required for precision diagnosis, but with this new technology, most of the
precision diagnosis of bearing fault can be covered by 'conanair' (patent
pending).
Future development
To meet the needs for use in hazardous areas, an explosion-proof version is
under development for release by the end of 2023. The company also expects that
its inexpensive vibration sensors will be widely used to detect abnormalities
in bearings, reduction gears, and various other machines, contributing to IT
systems.
