NKE Watteco Bob Assistant 50-70-001

BoB ASSISTANT monitors the vibration signature of a piece of equipment (such as a pump, ventilation, machine etc) in the 0 to 400Hz (± 6Hz) and 0 to 12.4kHz (± 200Hz) ranges every 5 minutes (can be adjusted).

Bob can be implemented on numerous types of machines of different industries, for instance:

1. Manufacturing
2. Energy
3. Automotive
4. Oil 
5. Gas
6. Facility management 

After the initial automatic learning period (7 days), the sensor alerts in case of vibration drift, allowing maintenance teams to intervene before a breakage or failure. Data transmission over the public or private LoRaWAN® network is done periodically or immediately in case of alert:

• Exceeding the vibration drift threshold (adjustable)
• Machine on/off (adjustable)

The sensor is equipped with:

• A button for activation and deactivation,
• RGB LED to monitor configuration and pairing to the network,
• 2 magnets to facilitate the installation of the sensor on the equipment (other alternatives are possible such as gluing, riveting, screwing).

Bob assistant uses an on-board artificial intelligence is 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).

Battery lifetime expectancy: 2 years with a configuration of 8 transmissions per day.Applications:
