Temperature sensor Milesight EM500-PT100

The Milesight EM500-PT100 is a robust industrial temperature sensor designed for accurate and stable measurements across a wide range. Manufactured with platinum sensing material, it reliably measures temperatures from -200 °C to 800 °C. The sensor is IP67-rated for water resistance, UV-resistant and vibration-resistant, and supports LoRaWAN® wireless communication for long-range, low-power data transmission. It is powered by a long-life lithium thionyl chloride battery (19000 mAh) and supports easy configuration via NFC. Mounting options include wall, pole and DIN rail installations.

Advantages

The EM500-PT100 offers stable and precise temperature measurement due to its platinum sensing element and wide operating range. Its IP67 protection, UV and vibration resistance enable reliable operation in harsh environments. LoRaWAN® connectivity provides secure long-range wireless transmission with low power consumption, enabling up to 10 years of battery life with a 10-minute reporting interval. NFC configuration simplifies on-site setup and maintenance.
