Sensor
Senzary llc. uses the BOB Assistant by nke WATTECO wireless sensor with embedded artificial intelligence.
BoB Assistant
The sensor analyzes the vibration signature of an industrial equipment, ensuring its remote monitoring. The data is transmitted via a public or private LoRaWAN ® radio frequency network.
APPLICATIONS
- Supervision of industrial installations equipped with motors (pumps, ventilation, cooling unit, …).
- Optimization of maintenance operations.
BENEFITS & FEATURES
- LoRaWAN ®, Class A
- Easy to install and ease of use
- > 2 years of autonomy
- Measuring ranges / accuracies:
– Vibration: 0-400Hz / ± 6Hz and 0-12.4kHz / ± 200Hz
– Temperature: -20°C to +55°C / ± 1°C
CERTIFICATION
- RoHS, CE
The sensor monitors the vibration signature of an equipment (pump, ventilation, etc.) on the ranges 0 to 400Hz (± 6Hz) and 0 to 12.4kHz (± 200Hz) every 5 minutes adjustable).
After an automatic learning period of 7 days, the sensor alerts in case of vibration drift, allowing maintenance teams to intervene before a breakage or failure.
The data transmission on public or private LoRaWAN ®network is done periodically or immediately in case of alert:
– Exceeding the vibration drift threshold (adjustable).
– Machine on/off (adjustable).
Installation and commissioning is quick and easy.
The sensor is equipped with:
– A button for activation and deactivation,
– An RGB LED to monitor configuration and association on the network,
– 2 magnets facilitating the installation of the sensor on the equipment (also possible by gluing, riveting, screwing…).
Each sensor is identified by a QR code on the label.
The data pre-processed by the on-board artificial intelligence is gathered in a report transmitted on 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/2000mAh battery, the autonomy of the sensor is more than 2 years with a configuration of 8 transmissions per day.
Integrated with Senzary IoTLogIQ platform for advanced analytics, device management and addtional sensors

FREQUENTLY ASKED QUESTIONS
BOB is equipped with a motion sensor to measure the vibrations along the X, Y, and Z axes. It can identify faults via the vibration Fourier transform, which shows the vibratory signature.
When in operation, and after baseline learning: BOB measures the equipment vibration periodically without sending a message. If all goes well, he sends a report every 6 hours with a summary of the measurements of this period. In the event of a vibration anomaly, it sends an alert immediately.
Some machines have several operating modes. BOB can learn these different modes of operation through artificial intelligence and identify them later, or even adapt to their changes.
BOB operates on a LoRa network.
LoRaWAN gateways are installed throughout your facility to ensure optimal coverage. LoRa connectivity benefits include long battery life on the sensors and excellent long-range coverage, regardless of facility size, you are covered.
Once BOB has been installed and learned the vibratory pattern of the machine, it should not be moved. The vibrations depend precisely on the area where BOB was initially placed. If it is moved, the vibratory signature will change and no longer correspond to what has been learned. If this is the case, either BOB can learn the vibrations of the new zone on its own, or it will go into alert mode because it “perceives” it has detected a failure: if so, it will be necessary to reset it!
BOB pauses and starts learning again when the machine reboots. It is not ideal to put a BOB sensor on a machine that rarely is on.
There must be a good mechanical contact (coupling) between BOB and its support to ensure proper vibration measurement. There are several ways to affix BOB:
- by magnetization
- by a clamp
- by gluing via double-sided tape
- by screwing
BOB runs both indoors and outdoors because it is robust and resistant to rain and dust (IP 68). However, the weather conditions, especially the temperature, can alter the battery and degrade the autonomy.
BOB is equipped with artificial intelligence, and it can learn the vibratory signatures of equipment and deduce anomalies. Initially, BOB does not know any equipment. When turned on, it must be placed on the machine: it will listen deeply to the vibrations of the machine for a few hours, then slightly for a few days. After seven days, BOB considers that it knows the machine and goes into normal operation. During the learning period, the results provided by BOB are therefore necessarily limited.
The BOB Assistant data and reports are collected and available on a web dashboard and mobile devices, using the account that you created when the sensors were installed. From there, you can explore BOB results, log your analyses, and export essential data. It is also possible to synchronize the platform’s analyzes to your own databases through standard APIs.
