Pt100 temperature sensor EM500-PT100

with housingwall-mountDIN rail

Overview
The EM500-PT100 is an industrial platinum (PT100) temperature sensor designed for high-accuracy, long-term monitoring in demanding environments. It integrates a 3-wire PT100 probe, LoRaWAN® wireless transmission, NFC configuration and a low-power architecture for extended battery life while maintaining IP67 protection.

Key Features

• Platinum PT100 probe for precise and stable temperature measurement
• Selectable probe measurement ranges: T050 (-200 °C ~ 50 °C), T200 (-50 °C ~ 200 °C), T500 (-50 °C ~ 500 °C), T800 (-50 °C ~ 800 °C) — customizable -200 °C ~ 800 °C
• LoRaWAN® connectivity for long-range, low-power deployments; supports OTAA/ABP Class A
• Rugged housing: IP67 protection, UV and vibration resistant
• Up to 10 years battery life with typical reporting intervals (19000 mAh ER34615)
• On-site NFC configuration and USB Type-C console for commissioning

Applications

• Industrial equipment and factory temperature monitoring
• Boiler, furnace and process temperature control
• Cold chain, laboratory and metrology applications
• Any scenario requiring high-accuracy, long-term temperature logging

Cloud & Integration
Compatible with Milesight IoT Cloud for visualization, automated triggers, scheduled reports and real-time alerts. Mobile apps (Android & iOS) and standard LoRaWAN integrations enable seamless device management and third-party platform connectivity.

Easy Configuration
NFC-based configuration via Milesight ToolBox (mobile/PC) and USB Type-C console for parameter tuning and commissioning. NFC enables on-site parameter changes without opening the enclosure.

Installation
Flexible mounting options: pole mounting, wall mounting and DIN rail mounting for diverse industrial deployments.
