Milesight EM500-PT100 T200 LoRaWAN Temperature Sensor -50 to +200 °C (EU868, IP67)

The Milesight EM500-PT100 (T200) is a rugged LoRaWAN temperature sensor built for accurate monitoring across -50 to +200 °C. It fits a wide range of real deployments—from cold storage areas to warm process environments—while keeping installation simple by using long-range LoRaWAN connectivity. The device uses a PT100 platinum probe with a 3-wire connection and delivers 0.1 °C resolution, making it well suited for trend monitoring, documentation, and alarms.

For dependable field operation, it can store up to 1,000 records locally during temporary connectivity issues and retransmit data once the network is available again. You can also enable threshold alarms (too hot/too cold) and change alarms to highlight unexpected shifts early—useful for quality assurance, process stability, and equipment protection.

Commissioning is straightforward via NFC using a phone, with additional configuration options via downlink or the internal USB-C port for configuration/console access. With an IP67-rated enclosure and flexible wall, pole, or DIN-rail mounting, it’s ready for industrial installations.
