What is wireless vibration monitoring, and is it reliable enough for critical machines?

Wireless vibration monitoring fits battery-powered sensors on equipment to collect vibration and temperature at regular intervals, sending data over industrial Bluetooth to a gateway and on to the cloud. DHMSCare sensors use industrial-grade Bluetooth 5.0 Class 1 with 60–80 m to the gateway inside a plant and 300 m line of sight, plus a repeater for another 50 m; sensors are IP69-rated and work in −40 to 80 °C ambient. DHMSCare watches critical machines with this system, and its alerts are accurate in 90%+ of cases.
