Industrial Dual-Channel LoRaWAN Temperature Transmitter for PT100 Sensors

The Dragino LTC2-LB is an industrial LoRaWAN temperature transmitter designed for accurate remote temperature monitoring using up to two 3-wire PT100 temperature probes. It converts high-precision PT100 measurements into LoRaWAN data, enabling reliable long-range wireless monitoring across industrial, laboratory and environmental applications.

The LTC2-LB features two independent 24-bit ADC channels, factory calibrated to provide highly accurate resistance and temperature measurements over a wide operating range. It supports various Dragino PT100 probes, including standard, food-grade, low-temperature, high-temperature and ultra-high-temperature models, allowing the device to be adapted to a wide variety of industrial applications.

Operating as a LoRaWAN Class A device, the LTC2-LB supports OTAA, Adaptive Data Rate (ADR), Bluetooth configuration, wireless OTA firmware updates and remote configuration via LoRaWAN downlinks. Integrated temperature alarms, data logging and battery monitoring provide reliable unattended operation for long-term deployments.

Powered by an 8500 mAh Li-SOCl₂ battery, the transmitter offers an operating life of approximately 2 to 10 years, depending on reporting interval, LoRaWAN coverage and operating conditions. Ultra-low power consumption makes it suitable for installations where external power is unavailable.

The LTC2-LB is an ideal solution for industrial process monitoring, cold chain applications, food production, laboratories, HVAC systems, boilers, ovens, manufacturing equipment and any application requiring reliable long-range temperature monitoring.

Please note: The LTC2-LB does not include a PT100 probe. Compatible Dragino probes such as DR-SI, DR-LT, DR-HT, DR-UHT, DR-FSA and DR-FT are ordered separately according to the application.
