Flammable gas leaks in industrial and daily environments (such as kitchens that use natural gas) and can be combustible when the flammable gas concentration reaches the alarm value set by the alarmgas detectorDetection alarm, combustibleGas alarmSound and light alarm signals are issued to remind people to take safety measures such as evacuation, forced ventilation, and equipment shutdown. WhileGas alarmIt can be linked to related equipment, such as leakage in factory production, storage and transportation, it can drive exhaust, cut off power supply, spray and other systems to prevent explosions, fires, poisoning accidents, and ensure safe production. It is commonly used in chemical plants, petroleum, gas stations, steel plants, and other places where flammable gas is generated.
Flammablegas detectorAlarm installation specifications:
1. Its location should be within 1m around the valve, pipe interface, air outlet or leakage point, as close as possible, but not affecting the operation of other equipment, and try to avoid high temperature and high humidity environment.
2. When used for large-area gas detection, the probe arrangement of 10-12 square meters can be used, and the detection and alarm effect can also be achieved.
3. The installation method can be roof hoisting, wall installation or pinch pipe installation. The installation should be secure and reliable, considering ease of maintenance and calibration.
4. Installation height: When detecting hydrogen, natural gas, city gas and other gases with a specific gravity of less than air, it should be installed about 1 meter away from the roof; When detecting gases such as liquefied petroleum gas with a specific gravity greater than air, it should be installed at a distance of about 1.5-2 meters from the ground.
5. The wiring should be a three-core shielded cable, and the diameter of a single wire is greater than 1 square millimeter. The shield must be grounded when wiring.
6. The on-site wiring should be threaded through the pipe, the pipeline used should meet the fire protection requirements, and the connection between the pipe and the probe should meet the fire protection requirements.
7. Mount the sensor downwards.
8. In the event of a power outage, the wiring should be wired, and the probe should be debugged after confirming that the wiring is correct.
9. Calibrate at least once a year to guarantee accuracy.
