Conventional hard-wired solutions are not always convenient, or practical, which has accelerated the development of wireless solutions. Wireless devices are quick and easy to install, without the need for expensive cabling, and bring solutions to applications that previously might not have been possible.
Whereas early wireless systems presented challenges with reliability and performance, often associated with battery life, these challenges have long since been overcome with products whose integrity is no longer in doubt. And they are being deployed to resolve a diverse range of mission-critical challenges across an equally diverse range of industrial applications.
Take, for example, the case of a well-known automotive manufacturer, renowned for its high performance and luxury cars. Cost efficiency is maintained by having a production line that is ‘always on’. Put another way, any unintended interruption can be expensive. So when this particular manufacturer had a problem with the machinery that moves the chassis down the line, it had to act fast. The motors were failing, bringing the line to a complete halt.
An investigation was launched to discover the root cause of the problem. Vibration may have been the reason, but it did not give the whole answer as to why the high-resistance joints were failing.
