What is wireless vibration monitoring, and is it reliable enough for critical machines?
Yes, for condition monitoring. Battery-powered sensors on your machines take vibration and temperature readings at regular intervals and send them over industrial Bluetooth to a gateway and on to the cloud. DHMSCare sensors use industrial-grade Bluetooth 5.0 Class 1: 60–80 m to the gateway inside a plant, 300 m line of sight, and another 50 m with a repeater. They 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.
How wireless vibration monitoring works
A battery-powered sensor bonds to each bearing housing and takes vibration and temperature readings at regular intervals. It sends them over industrial Bluetooth to a gateway, which forwards them to the cloud platform.
The DHMSCare DS310 measures 0–6000 Hz with a ±16 g range and records a detailed three-axis waveform with each capture. DHMSCare uses that data to diagnose 60+ rotating-equipment faults across shafts, bearings and gears.
What keeps the link reliable
DHMSCare sensors use industrial-grade Bluetooth 5.0 Class 1. Inside a plant they typically reach the gateway from 60–80 m, and a DR100 repeater adds another 50 m past weak spots.
If the network drops, the gateway stores the readings first. The platform shows when any sensor or gateway goes offline, so a gap in the data does not go unnoticed.
The sensors are IP69-rated, work in −40 to 80 °C ambient and run five years on the battery after activation, or three on the DS400 and DS420.
Where wireless is not the right tool
Wireless monitoring is for condition monitoring. A protection system that must trip a machine within milliseconds, such as API 670 protection on a turbine, stays wired.
DHMSCare monitors and warns your team early, and people decide when to stop a machine. Keep your existing protection relays and trip systems in place.
For everything else, such as pumps, fans, motors, gearboxes and compressors, wireless monitoring gives you the readings without a single new cable.
Questions buyers also ask
Will metal walls and machines block the signal?
They can shorten the range. Plan the gateway position with the layout in mind, and add a DR100 repeater where the signal is weak.
How long do the sensor batteries last?
Five years after activation, or three on the DS400 and DS420.
Can wireless sensors be used in hazardous areas?
DHMSCare offers hardware certified under IECEx, the international scheme for equipment used in explosive atmospheres. The certificate states which models and zones it covers.
