Guardian of Gas Safety: Nexisense Gas Pressure Monitoring Terminal's 24/7 Protection

Urban gas pipeline networks are like the "lifelines" of a city, carrying the gas needs of thousands of households. However, with the continuous expansion of urban scale, factors such as pipeline aging, construction interference, and geological changes are intertwined, and safety risks such as pressure anomalies and leakage hazards always exist. How to achieve 24/7 precise monitoring and rapid response at key nodes has become a realistic challenge that gas companies must face. The Nexisense gas pressure monitoring terminal, as an IoT sensing device specially designed for urban gas safety, is injecting strong protective power into pipeline network safety with its high reliability and intelligent features.

Stringent Explosion-Proof and Protection, Adapting to Extreme Environments

The gas environment is inherently a high-risk explosive location, with extremely high requirements for the intrinsic safety of monitoring equipment. From the beginning of its design, the Nexisense gas pressure monitoring terminal strictly complies with national explosion-proof standards, meeting the requirements of GB/T 3836.1-2021 and GB/T 3836.4-2021, and has obtained Ex ib IIB T4 Gb explosion-proof certification. This means that even in environments filled with flammable gases, the equipment can operate safely and stably without generating sparks or high-temperature surfaces sufficient to cause explosions.

At the same time, the terminal has an IP68 protection rating, which can completely resist dust intrusion and maintain normal operation under long-term water immersion conditions. Whether it is the humid water accumulation in underground pressure regulating wells, rain and snow erosion in outdoor pressure regulating stations, or the oil-gas mixed environment in filling stations, Nexisense can achieve reliable deployment in all-weather and all-scenario conditions. This extreme environmental adaptability is difficult to achieve with traditional wired monitoring solutions.

High-Precision MEMS Sensing Technology, Reliable Data Assurance

Minor changes in pipeline network pressure are often early signals of leaks, blockages, or abnormal gas usage. The Nexisense terminal is equipped with high-precision MEMS pressure sensing elements, combined with advanced digital compensation algorithms, effectively suppressing the influence of environmental factors such as temperature drift and humidity interference on measurement, achieving long-term stable high-precision data acquisition.

In addition to the core pipeline network pressure monitoring, the terminal also reserves flexible expansion interfaces, which can seamlessly connect to liquid level sensors, water immersion sensors, and combustible gas concentration detectors, forming a "one device with multiple functions" comprehensive monitoring node. This modular design not only reduces deployment costs but also reserves ample space for future in-depth applications of smart gas platforms.

In actual operation, the pressure data resolution can reach 0.1kPa level. Combined with cloud algorithm analysis, it can promptly detect abnormal patterns such as "slow leaks" or "sudden pressure drops," providing a solid data foundation for preventive maintenance.

NB-IoT Communication Empowerment, Truly Achieving Remote Real-Time Supervision

Traditional monitoring methods rely on manual inspections or wired transmission, resulting in delayed response and high costs. The Nexisense gas pressure monitoring terminal adopts mature NB-IoT low-power wide-area network technology to achieve long-distance, low-power, wide-coverage wireless data transmission. Without on-site wiring, key data such as pressure, temperature, and status can be uploaded to the cloud platform, management center, or mobile APP in real time.

The deep coverage characteristic of NB-IoT is particularly suitable for signal-weak areas such as underground well chambers and remote pipeline networks. Even in pressure regulating wells several meters underground or deeper, data can still be stably transmitted. The terminal is equipped with a high-performance 3.6V lithium thionyl chloride battery, which can support more than 8 years of continuous operation with a single replacement, significantly reducing operation and maintenance frequency and manpower investment.

When abnormalities such as pressure exceeding the set threshold, low battery, or water immersion alarm are detected, the system will immediately push alerts through multiple channels such as SMS, WeChat, and Enterprise WeChat. Managers can quickly analyze and organize responses regardless of location, effectively shortening the "golden time" for accident handling.

Typical Application Scenarios and Actual Value

The Nexisense gas pressure monitoring terminal has been verified and promoted in multiple urban gas projects, covering the following key locations:

Urban Main Pipeline Network and Branch Pipeline Network

By deploying monitoring points at key nodes, full-network pressure situation awareness is achieved, helping the dispatching center to adjust gas supply strategies in time and avoid local overpressure or underpressure.

Pressure Regulating Stations and Pressure Regulating Wells

The underground pressure regulating well environment is harsh and difficult to inspect. The terminal's explosion-proof + IP68 + ultra-long battery life features play a huge advantage here and have become the preferred equipment for many gas companies' "smart well chamber" renovations.

Filling Stations and Industrial Users

For CNG/LNG filling stations and large industrial park gas users, the terminal can simultaneously monitor inlet pressure and storage tank liquid level, forming closed-loop safety control.

Actual application data shows that after deploying Nexisense terminals, the average time to discover abnormal events is shortened by more than 70%, inspection frequency is reduced by 60%, and the overall pipeline network safety level is significantly improved. These results not only reduce safety risks but also save considerable operation and maintenance costs for enterprises.

Assisting Smart Gas Construction and Moving Towards Digital Transformation

Under the dual strategic background of "Digital China" and "Safe Development," the traditional gas industry is accelerating its transformation to intelligence. The Nexisense gas pressure monitoring terminal is not only a single sensing device but also an important component of the smart gas ecosystem. It seamlessly connects with cloud platforms, big data analysis, and GIS pipeline network systems, providing real-time data support for pipeline network health assessment, risk warning, and emergency command.

In the future, with the further integration of technologies such as 5G-A and edge computing, this type of terminal will also achieve lower latency and richer multi-sensor fusion capabilities, promoting the complete shift of gas safety management from "post-event handling" to "pre-event prevention."
