HM200 WIRELESS SERIES
HM200H Wireless Temperature & Pressure Transmitter
The HM200H is a wireless integrated temperature and pressure transmitter with modular design and multi-frequency networking. It measures pressure from -0.1 to 60 MPa and temperature from -40 to 150°C (integrated) or -200 to 850°C (external PT100), supporting 4G, LoRa, WiFi, Zigbee, LoRaWAN and NB-IoT protocols.

Product Overview
The HM200H is a 2-in-1 wireless transmitter that simultaneously measures both pressure and temperature, reducing installation costs and simplifying field instrumentation. With a pressure measurement range from -0.1 to 60 MPa and an integrated temperature range of -40 to 150°C, it covers the majority of industrial monitoring scenarios in a single compact device.
For applications requiring extended temperature monitoring, the HM200H supports external PT100 sensors (-200 to 850°C) and K-type thermocouples (-270 to 1372°C), making it suitable for high-temperature environments in petrochemical plants, boiler systems, and heat treatment facilities. Selectable pressure accuracy of ±0.5%, ±0.25%, or ±0.1% FS ensures optimal performance for different precision requirements.
The multi-protocol wireless architecture supports 4G, LoRa, WiFi, Zigbee, LoRaWAN, and NB-IoT, allowing seamless integration into existing network infrastructures. Data is transmitted via TCP, UDP, MQTT, or MODBUS-TCP protocols to cloud monitoring platforms. The built-in 38Ah rechargeable lithium battery provides over 24 months of continuous operation, minimizing maintenance visits in remote locations.
Engineered with a modular design, the HM200H features tool-free sensor head replacement and field-upgradeable firmware. The 316L stainless steel wetted parts and IP67 standard protection (optional IP68) ensure reliable operation in harsh industrial environments from -20 to 85°C. Optional explosion-proof certification (Ex d IIC T6) makes it suitable for hazardous area installations.
