Dragino LTC2-HT LoRaWAN High Temperature PT100 Sensor (EU868)

Transmitter operating limit: -40°C to +65°C. The high-temperature range applies only to the external probe.

The Dragino LTC2-HT is an industrial LoRaWAN high-temperature monitoring solution designed for remote temperature measurement in demanding industrial environments, manufacturing facilities and thermal processing applications.

The device combines the Dragino LTC2 LoRaWAN Temperature Transmitter with one external high-temperature PT100 Class A probe, providing a wireless temperature monitoring solution for applications requiring measurements significantly above the range of conventional temperature sensors.

The supplied high-temperature probe offers a measurement range from −70°C to +450°C, according to the manufacturer's current specifications, making it suitable for monitoring heated equipment, industrial processes and thermal installations.

The probe features a 3-meter connection cable and a compact metallic insertion-type sensing element, allowing temperature measurements at the required location while keeping the wireless transmitter at a safe distance from the heat source.

The LTC2 transmitter supports two independent 3-wire PT100 measurement channels, allowing an additional compatible PT100 probe to be connected when required.

The device converts the resistance measurements of the connected PT100 sensor into temperature readings and transmits the data wirelessly to a compatible LoRaWAN gateway and network server.

Operating on the EU868 frequency band, the LTC2-HT uses LoRaWAN Class A technology for long-range wireless communication with low power consumption.

The transmitter is powered by a non-rechargeable 8,500 mAh Li-SOCl₂ battery, enabling long-term operation without permanent external electrical power.

Actual battery life depends on the reporting interval, LoRaWAN signal conditions, ambient temperature and operating configuration.

The LTC2-HT also supports local temperature data logging, allowing historical measurements to be stored and subsequently retrieved through supported LoRaWAN commands.

This capability is particularly useful for industrial applications where maintaining a temperature history is important or where temporary wireless communication interruptions may occur.

The device supports remote parameter configuration through LoRaWAN downlink commands, while local configuration and firmware maintenance can be performed through its serial interface.

Its PT100 resistance measurement channels are factory-calibrated to support reliable conversion of sensor readings into temperature values.

The Class A PT100 sensing element is designed for precision resistance-based temperature measurement. However, the actual measurement uncertainty depends on the probe, calibration and installation conditions, especially at elevated temperatures.

The LTC2-HT is suitable for applications such as industrial machinery temperature monitoring, thermal processing equipment, heated pipelines, industrial ovens, energy installations and manufacturing process supervision, provided the probe and mounting arrangement are compatible with the environment.

The high-temperature sensing element can be positioned at the measurement point, while the LoRaWAN transmitter should be installed outside the high-temperature zone, within its specified environmental operating limits.

With its combination of high-temperature PT100 sensing, long-range LoRaWAN connectivity, battery-powered operation and historical data logging, the Dragino LTC2-HT provides a flexible solution for industrial temperature monitoring and Industrial IoT applications.

Important: The −70°C to +450°C measurement range applies to the external PT100 probe, not to the LTC2 transmitter enclosure. The transmitter must remain within its own specified operating temperature limits. The product is intended for temperature monitoring and should not be treated as a certified safety temperature limiter without separate engineering validation.
