Applications of the transmitter


This LoRa / LoRaWAN 4/20mA analogue radio transmitter is specifically designed for industrial applications (construction industry – water management – rail industry, etc.).
Self-powered, it connects to all types of analogue probes with 4/20mA interface and reassemble the signal.

This transmitter can meet all types of applications including pressure, flow, fluid levels (water, fuel oil, gas, etc.) / gauges (ultrasonic probes), etc.

The robustness of our LoRa / LoRaWAN transmitter – IP 65 enclosure – and its high environmental tolerance (-20°C / +55°C) allow it to withstand any type of environment.

Data from the sensor can be transmitted according to two radio protocols : the LoRa Enless Wireless private mode (proprietary) or the LoRaWAN mode (operated or private). To learn more about these communication protocols, see our dedicated LoRa LoRAWAN page.

This transmitter incorporates high-performance D-type batteries and thus gives it a very high autonomy of up to 15 years.
