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 probability.

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 is replaced.

Machine vibration knowledge and battery values can be reset either through the HMI interface or network Downlink command.
