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.

Frequently Asked Questions

The best protocol depends on your application: NB-IoT and 4G are ideal for wide-area deployments with cellular coverage. LoRa excels in long-range, low-power scenarios like remote sites. Wi-Fi suits indoor installations with existing network infrastructure. Zigbee is best for dense mesh networks with many sensors. Ethernet provides the most reliable wired connection where cabling is feasible. Fiber optic is used in electromagnetically harsh environments.

Battery life depends on the wireless protocol selected, transmission interval, and environmental temperature. The built-in 7.4V/5000mAh lithium battery provides extended operation, especially with low-power protocols like LoRa and NB-IoT. For applications requiring continuous monitoring, the 9-36V DC power option or solar panel power supply ensures uninterrupted operation. Contact our engineering team for specific battery life estimates based on your configuration.

Yes, but each HM110 unit is configured for one sensor type at the time of ordering. You can choose PT100 (Class A) or PT1000 (Class A) for RTD measurement (-200°C to 500°C), or K-type or S-type thermocouple for higher temperature ranges (up to 1600°C). The sensor type is specified in the model code during ordering. Cold junction compensation and non-linear correction circuits are built in for thermocouple configurations.

Transmission distance varies by wireless protocol: LoRa can achieve several kilometers in open terrain, NB-IoT and 4G work anywhere with cellular coverage (virtually unlimited range), Wi-Fi typically covers 50-100 meters indoors, Zigbee reaches 100-300 meters with mesh networking capability, and Ethernet/Fiber optic distance depends on cable specifications. For most industrial applications, LoRa and NB-IoT provide the best balance of range and power efficiency.

Yes, the HM110 is rated for a typical working pressure of 40 bar with a maximum pressure of 300 bar. The probe is constructed from 304/316L stainless steel with optional PTFE lining, making it compatible with a wide range of corrosive and high-pressure media. For specific high-pressure requirements, contact our engineering team to confirm compatibility with your process conditions.

The HM110 supports multiple integration paths. For cloud-based systems, NB-IoT and 4G protocols transmit data directly to cloud platforms. For local networks, Wi-Fi, Ethernet, and Zigbee connect to local gateways or SCADA systems. Our HL10 series gateways (HL10A LoRa Gateway, HL10B Display Terminal, HL10C 4G Router, HL10D WiFi/Ethernet Gateway) are designed specifically to receive and forward HM110 data. The HL100 Power and Environment Monitor provides a complete monitoring solution with built-in data logging and alerting.
