Dragino LTC1 PT100 RTD Temperature Sensor (LoRaWAN, NB-IoT & LTE-M)

 

The Dragino LTC2 PT100 RTD Temperature Sensors are designed for accurate, long-term temperature monitoring using industry-standard PT100 RTD probes. They are suitable for applications where stable, repeatable measurements are required across industrial processes, laboratories, environmental monitoring, and infrastructure monitoring.

PT100 RTD Probe Options The LTC2 model supports a single PT100 RTD probe for straightforward temperature measurement. The LTC2 model supports two PT100 RTD probes, which is useful where two measurement points are needed from one device installation.

Multi-Network Connectivity The LTC2 platform is available with support for LoRaWAN, NB-IoT, and LTE-M networks. This allows the same sensor family to be deployed across private LoRaWAN networks or carrier-operated cellular networks, depending on coverage, installation environment, and operational requirements.

Enhanced Functionality with Telemetry2U Integration While the LTC2 sensors can be connected to compatible third-party platforms, Telemetry2U is the recommended option for customers seeking a supported, end-to-end monitoring solution. When integrated with the Telemetry2U IoT platform, the sensors can be configured for dashboards, historical data logging, alerts, and device management.
