SMART INDUSTRY BoB ASSISTANT Predictive maintenance 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 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  RoHS, CE *Photo not contractual 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.
