Product Overview
Specifying for the first time? Pair the HM110 wireless platform with the right sensing element by following our two-stage temperature sensor selection framework—covering range, accuracy class, and protection assembly.
The HM110 Wireless Temperature Sensor is a smart industrial-grade sensor designed for remote temperature monitoring across diverse industrial environments. Featuring built-in wireless transmission capabilities, it directly measures temperatures from -200°C to 500°C using PT100/PT1000 RTD elements, or up to 1600°C with K-type and S-type thermocouple elements. The sensor integrates German thin-film resistance technology for exceptional accuracy and fast thermal response.
What sets the HM110 apart is its versatile wireless connectivity. Choose from seven wireless protocols — NB-IoT, 4G, LoRa, Wi-Fi, Ethernet, Zigbee, or Fiber Optic — to match your specific infrastructure requirements. Whether monitoring a single point in a heating system or deploying hundreds of sensors across a large industrial facility, the HM110 adapts to your communication needs.
Built with 304/316L stainless steel wetted parts and IP65/IP67 protection, the HM110 handles demanding environments including high-pressure systems up to 300 bar. Multiple power options — lithium battery (7.4V/5000mAh), DC power (9-36V), or solar panel — provide installation flexibility for both accessible and remote locations. The optional LED display enables on-site temperature reading without additional equipment.

Key Features
Multiple Wireless Protocols
Choose from 7 wireless communication options — NB-IoT, 4G, LoRa, Wi-Fi, Ethernet, Zigbee, and Fiber Optic — to seamlessly integrate with your existing industrial monitoring infrastructure.
Ultra-Wide Temperature Range
Measure from -200°C to 500°C with PT100/PT1000 RTD elements, or up to 1600°C using K-type and S-type thermocouple sensors. One platform covers virtually all industrial temperature applications.
High Accuracy Measurement
Achieves ±0.1%FS accuracy with German thin-film resistance elements. Long-term stability of ±0.1%FS/year and temperature drift of only 0.008%FS/°C ensure reliable readings over extended periods.
Industrial-Grade Protection
IP65/IP67 rated housing with 304/316L stainless steel wetted parts withstands harsh environments. Pressure rating up to 300 bar and vibration resistance (10-60Hz) ensure durability in demanding installations.
Flexible Power Options
Built-in lithium battery (7.4V/5000mAh) for cable-free deployment, 9-36V DC for permanent installations, or solar panel power for remote locations. Low energy consumption extends battery life significantly.
Fast Thermal Response
Response time as fast as 1 second with Ø1.5mm thermocouple probes. Standard probes achieve T₅₀ of 2.3 seconds and T₉₀ of 5.4 seconds — critical for processes requiring real-time temperature monitoring.
