How IoT sensors changed condition monitoring
Wireless sensors turned condition monitoring from a periodic route into a continuous, always-on signal.
Wireless sensors turned condition monitoring from a periodic route into a continuous, always-on signal.
Traditional condition monitoring meant a technician walking a route with a handheld analyser — accurate, but only as current as the last visit. A fault that started the day after the route ran had a month to develop unseen. Wireless sensors collapsed that gap to zero.
- What actually changed
- Coverage — monitoring reached assets that were too remote, too hot or too hazardous for regular routes
- Resolution — a trend built from hourly readings reveals patterns a monthly snapshot never could
- Cost — a wireless sensor on a pump costs a fraction of the analyst's route time it replaces
- Response — alerts reach the right person in minutes, not at the next review meeting
The physics. Vibration still means mechanical wear, temperature still means friction or overload, ultrasonics still mean leaks and early bearing stress. Sensors made the signals continuous — reading them is still a maintenance skill.
- What didn't change
Put continuous monitoring on the assets where a surprise failure hurts most, and keep routes for everything else. The two approaches complement each other — sensors cover the gaps between human inspections, humans cover the judgement calls sensors can't make.
