Watteco BOB Assistant V2 - LoRaWAN Vibration Sensor
LoRaWAN 868EU, Class A, IP68
BoB ASSISTANT® is a robust sensor designed for monitoring the vibration signature
of a piece of equipment (pump, ventilation, etc...) in industrial applications. It has an IP68 rating and certified fire restinance according to UL94-HB. Also available with ATEX Zone 2 certification upon request.
After a learning period of 7 days, the sensor alerts
in case of vibration drift, allowing maintenance
teams to intervene before a breakage or failure.
Data transmission over the LoRaWAN® network is
done periodically or immediately in case of alert:
- Exceeding the vibration drift threshold
- Machine on/off
Both conditions have adjustable thresholds.
How it works:
After a learning period of 7 days, a baseline is created for the monitored machine. The data is pre-processed by the on-board artificial
intelligence and gathered in a report transmitted over
the LoRaWAN® network every 180 minutes.
The sensor periodically reports the machine's
operating time over the last 180 minutes, the rate of
vibration drift recorded over this period, the battery
level, the temperature, and a predictive failure
Machine status alerts (Start/Stop) are also available
(can be inhibited by Downlink control).
Powered by a 3.6V/2100mAh battery, the autonomy
of the sensor is more than 3 years with a
configuration of 8 transmissions per day.
Machine vibration knowledge is stored in flash and
applied back when the device is restarted or battery
Machine vibration knowledge and battery values can
be reset either through the HMI interface or network
