EM500-PT100 – LoRaWAN Temperature Sensor with PT100 Probe – Milesight
General Description
The Milesight EM500-PT100 is a high-precision industrial temperature sensor using a 3-wire PT100 probe. Designed for demanding environments, it measures temperatures from -200°C to +800°C depending on the selected model (T050, T200, T500, or T800). Data is transmitted via ultra-low-power LoRaWAN®, ensuring up to 10 years of battery life with a 19,000 mAh battery. Thanks to its robust IP67 housing, simple setup via NFC or USB Type-C, and compatibility with the Milesight IoT Cloud platform, the EM500-PT100 is ideal for remote industrial applications.
