LoRaWAN Industrial Ultrasonic Range/Distance Sensor (ULR75)

Long-Range Non-Contact Distance & Level Monitoring

The Kibitron ULR75 Ultrasonic Range/Distance Sensor provides high-precision, non-contact measurement for industrial and smart city applications. Using ultrasonic sensing technology with built-in temperature compensation, it ensures reliable distance and level readings even in challenging conditions.

With a detection range of 280 mm to 7,500 mm and accuracy of ±(1 cm + 0.3% of distance), the ULR75 is ideal for horizontal distance measurement, tank and liquid level monitoring, parking systems, waste bin management, sewer and bottom-water level detection, object proximity, and automation control.

Data is transmitted securely over LoRaWAN® to a Kibitron gateway, then streamed to the Kibitron platform for real-time analysis, alarms, and reporting. The device supports Bluetooth v5.1 configuration, OTA firmware updates, and remote management, making deployment fast and user-friendly.

Built in a rugged IP66-rated enclosure and powered by a long-life 8500 mAh Li-SOCl₂ battery (up to 5 years operation), the ULR75 is engineered for long-term, maintenance-free deployments.

Please Note: All Kibitron LoRaWAN sensors require a LoRaWAN gateway and an active Kibitron software subscription to operate. These devices are not compatible with our RF-based gateways.

For the best experience, we recommend using our pre-provisioned LoRaWAN gateways, which arrive fully configured to communicate with the Kibitron platform.
If you need help selecting the right gateway or confirming compatibility, please contact our support team.
NB-IoT/LTE-M versions are also available for cellular applications.
