Our Reporter (Li Hua) In daily life, how can we achieve round-the-clock safety monitoring in corners where flammable and explosive gases may be present, preventing disasters before they ignite? Recently, reporters visited several security technology companies and industrial parks and discovered that explosion-proof gas sensors, seemingly minor devices, are acting as crucial “nerve endings” and playing an indispensable role as “invisible guardians” in numerous scenarios from kitchens to factories.
Scenario One: Guardians of the Urban “Lifeline” – Gas Pressure Regulating Stations and Pipeline Valve Wells
Application Site:
At the smart operation center of a city gas company, large screens display real-time gas concentration data from hundreds of gas pressure regulating stations and underground pipeline valve wells across the city. These data are sourced from explosion-proof combustible gas sensors buried underground or installed in sealed equipment rooms.
Role and Value:
“The main component of natural gas is methane. Once it accumulates in a confined space and encounters a spark, the consequences could be disastrous,” said Mr. Wang, the company’s Safety Director. “In the past, we relied on regular manual inspections, which were not only inefficient but also carried the risk of delayed detection. Now, these intrinsically safe (a type of explosion-proof) sensors can operate 24/7. Once the methane concentration reaches 20% of the lower explosion limit (LEL), the system immediately alarms and pinpoints the leak location. Operators can remotely shut off the relevant valves and dispatch personnel for repairs, eliminating risks at their source. They are the first and most reliable line of defense in protecting the city’s ‘lifeline’.”
Supporting Technology: These robust sensor systems form a complete IoT solution. The complete set of servers and software wireless module supports RS485, GPRS, 4G, WIFI, LORA, and LORAWAN protocols, enabling seamless data transmission from even the most remote or challenging locations back to the central monitoring platform.
Scenario Two: The “Safety Talisman” of the Catering Industry – Commercial Kitchens and Food Courts
Application Site:
Inside a large shopping mall’s food court, behind the bustling crowds, each catering merchant’s back kitchen quietly houses explosion-proof combustible gas sensors. These are interconnected with emergency gas shut-off valves, forming a comprehensive safety assurance system.
Role and Value:
Ms. Liu, the mall’s Property Safety Management Manager, shared a case: “Last summer, a restaurant’s gas hose was chewed through by a rat due to aging, causing a minor leak. The kitchen was operating at the time, and sparks from the stoves could easily have caused an explosion. Fortunately, the sensor installed above the gas pipeline emitted a sharp audible and visual alarm within seconds of the leak and interlocked to cut off the gas supply to the entire area. Staff quickly arrived to ventilate and handle the situation, averting a potential major accident. Since installing this system, both merchants and customers feel much more secure. It’s like an invisible ‘safety talisman’.”
Scenario Three: The “Reassurance” for Industrial Production – Petrochemical and Painting Workshops
Application Site:
In highly hazardous environments like petrochemical workshops, paint spraying areas, or chemical storage warehouses, the air may not only contain combustible gases but also toxic gases (such as hydrogen sulfide, benzene, carbon monoxide). Sensors here require higher protection ratings and detection accuracy.
Role and Value:
Mr. Zhao, a Safety Officer at a chemical plant, explained: “Our environment is very complex, with multiple potential hazards simultaneously. The composite explosion-proof gas sensors we deploy can not only detect combustible gases but also simultaneously monitor specific toxic gases and oxygen concentration (to prevent hypoxia or oxygen enrichment). Their presence provides the most direct life safety assurance for workers operating in these extreme environments. If values become abnormal, they immediately trigger a chain reaction, activating powerful ventilation systems and notifying personnel to evacuate. For us, they are not just a requirement of safety regulations but also a ‘reassurance’ for all employees.”
Supporting Technology: The data from these critical sensors is reliably transmitted via the integrated wireless modules (supporting RS485, GPRS, 4G, WIFI, LORA, LORAWAN), ensuring continuous monitoring and instant alerts regardless of the plant’s infrastructure challenges.
Technology Empowerment: The Smart Leap from “Remediation After the Fact” to “Pre-Warning”
The core role of explosion-proof gas sensors is to transform safety management from passive, lagging post-incident remediation to active, real-time pre-warning. By integrating with the Internet of Things (IoT) and big data cloud platforms, sensor data is aggregated and analyzed, enabling advanced functions such as trend prediction and equipment life, truly building a solid and reliable intelligent safety protection network.
Experts point out that with the acceleration of urbanization and increasing demands for production safety, the application scenarios for explosion-proof gas sensors are rapidly expanding from traditional industrial fields to urban public safety and smart home applications. This tiny “electronic nose,” with its precise and reliable performance, silently safeguards social tranquility and people’s lives and property. Its value as an “invisible guardian” of the city is becoming increasingly prominent.
