Temperature sensor Milesight EM500-PT100

The Milesight EM500-PT100 is a robust industrial temperature sensor designed for precise measurements across a wide range. Constructed with a platinum sensing element, it provides stable and accurate readings from -200 °C to 800 °C. The compact IP67-rated housing and vibration- and UV-resistant construction make the EM500-PT100 suitable for demanding environments. The sensor uses LoRaWAN® for long-range wireless communication and low power consumption, and supports cloud management via Milesight IoT Cloud. Configuration is available through NFC from a mobile phone or PC. The device can be mounted on walls, poles or DIN rails.

Advantages

The EM500-PT100 offers high-temperature stability and precision thanks to its platinum sensing element, and endures extreme temperatures from -200 °C to 800 °C. Its IP67 protection, UV and vibration resistance allow continuous operation outdoors and in industrial settings. LoRaWAN® connectivity ensures secure, long-range data transmission with low power draw, enabling battery life of up to 10 years under a 10-minute reporting interval. Integration with Milesight IoT Cloud provides dashboards, automatic triggers, regular reports, real-time alerts and mobile app management.

Suitable for

• Industrial process temperature monitoring
• Laboratory and research environments requiring precise temperature sensing

How to use

Install the EM500-PT100 in the required location using wall, pole or DIN rail mounting according to the site layout. Power on and configure the device using NFC from a compatible smartphone or PC to set network (LoRaWAN®) parameters and reporting intervals. Position the platinum temperature probe where accurate measurement is needed and ensure cable routing and mounting prevent mechanical stress. Register the device in Milesight IoT Cloud for visualization, alerts and reports, and verify connectivity and data reporting after setup.

Usage recommendations

For reliable long-term performance, verify that the sensor probe is compatible with the measured medium and environmental exposure. Use appropriate shielding or mounting to minimize mechanical shocks, and configure reporting intervals and thresholds in Milesight IoT Cloud to balance power consumption and monitoring requirements.
