Industrial High-Temperature PT100 Probe for LoRaWAN Temperature Monitoring
The Dragino DR-HT is an industrial high-temperature PT100 probe designed for use with the Dragino LTC1/LTC2-LB/LS LoRaWAN temperature transmitters. It enables accurate temperature monitoring in demanding industrial environments where standard temperature probes cannot withstand the required operating range.
The probe measures temperatures from -70°C to +450°C, making it suitable for industrial ovens, heating equipment, manufacturing processes, machinery, pipelines and other high-temperature applications. It uses a Class A PT100 resistance temperature detector, providing stable and reliable temperature measurements over a wide range.
The DR-HT features a compact stainless-steel insertion probe measuring Ø4.5 × 30 mm and is supplied with a 3-meter connection cable, allowing flexible installation away from the LoRaWAN transmitter.
When connected to an LTC1 or LTC2 transmitter, the measured temperature can be converted and transmitted through a LoRaWAN network to a compatible IoT platform or monitoring system. The LTC1 supports one PT100 monitoring channel, while the LTC2 supports up to two PT100 channels.
Please note that the DR-HT is a temperature probe only. The LoRaWAN transmitter must be purchased separately.
