The NB-IoT Smart Wireless Temperature Gauge plays an important role in smart district heating systems by enabling intelligent heat distribution and improving heating efficiency.

As winter approaches each year, district heating becomes an essential public service. Urban heating systems deliver thermal energy to residential and commercial buildings, ensuring a warm and comfortable indoor environment during the cold season. However, conventional heating systems often face several challenges.

One of the major issues is the uneven distribution of heat, which leads to both energy waste and insufficient heating in certain areas. The primary reason is the difficulty of collecting real-time data from distributed terminals. Parameters such as pipeline surface temperature, pipeline pressure, and indoor temperature and humidity cannot be monitored continuously, making it difficult to adjust heat distribution according to actual demand. In addition to traditional meter reading requires extensive wiring and high maintenance costs, while conventional wireless communication often suffers from weak signals and unstable transmission, resulting in data loss.

To address these challenges, Toprie's NB-IoT Smart Wireless Temperature Gauge provides a reliable and efficient solution.

The device integrates a high-precision temperature sensor and pressure sensor to ensure accurate measurements. An LCD display provides clear, real-time readings directly on the instrument. Based on the NB-IoT (Narrowband Internet of Things) network, the device features strong signal coverage, low power consumption, and stable wireless communication through the public cellular network, making it ideal for wide-area deployment.

The collected data can be transmitted directly to various IoT cloud platforms, including China Telecom IoT Platform, China Mobile OneNET, Huawei IoT Platform, TLINK, and other compatible cloud platforms. Users can conveniently monitor real-time and historical data through computers or mobile devices.

When abnormal temperature or pressure conditions are detected, the system can automatically send alarm notifications via WeChat, SMS, or phone calls, enabling maintenance personnel to respond quickly and minimize operational risks.

Powered by a built-in lithium battery, the instrument can operate continuously for more than five years, significantly reducing maintenance costs and eliminating the need for frequent battery replacement.

The wireless temperature gauge also features local historical data storage with breakpoint retransmission. If network communication is temporarily interrupted, all collected data are stored locally. Once the network connection is restored, the device automatically uploads the missing historical records to the cloud platform, effectively preventing data loss. In addition, measurement data can be exported locally via a USB interface, providing dual data backup for enhanced reliability and security.

Designed for harsh industrial environments, the instrument offers excellent resistance to moisture, water, dust, immersion, and explosion hazards. The pressure sensor provides outstanding temperature and long-term stability, while the temperature probe utilizes fine iron-sand thermal filling for improved sensitivity. Both integrated and remote probe configurations are available, allowing flexible installation for different measurement scenarios.
