Gas stoves typically require industrial and commercial point-type combustible EX gas detector. These devices comply with the national standard GB 15322.1-2019 and are suitable for use in restaurants, shopping malls, petroleum and petrochemical facilities, and other locations. They offer IP65/IP66 protection and explosion-proof certification.
1.Core Functions
Detection Range: Detects common combustible gases such as methane, propane, and hydrogen.
Technical Principle: Utilizes catalytic combustion and electrochemical combined detection technology, with built-in anti-poisoning and anti-interference components.
Linkage function: Supports relay outputs for coordinated gas supply shut-off.
Extended Functions: Supports RS485 communication for remote monitoring.
Based on the operating environment and safety requirements of your gas stove, we recommend the following detector types and related installation requirements:
2.Detector Type Selection
Point-Type Combustible Gas Detector for Industrial and Commercial Use: Utilizes a catalytic combustion and electrochemical combined detection principle to detect common combustible gases such as methane, propane, and hydrogen. With explosion-proof certification (Ex db IIC T6 Gb), it is suitable for complex environments such as the petroleum and chemical industries.
Infrared Optical Detector Principle: Detects methane and other alkane gases by utilizing the infrared absorption properties of gas molecules.
Applicable Scenarios: Complex industrial or commercial kitchens. Highly resistant to interference, but with a higher cost.
Laser Methane Detector: Principle: Utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology to identify the unique spectral fingerprint of methane using laser light.
3.Advantages
Precise and Anti-interference: Avoids false alarms from kitchen fumes, water vapor, vinegar, and other gases, responding only to actual leaks. Long-Life Anti-Poisoning: The core sensor has a lifespan of up to 10 years, eliminating the risk of silicon compound poisoning associated with traditional sensors.
Fast Response: Detects trace amounts of gas and issues an alarm within seconds, maximizing time for emergency response.
Installation Specifications
4.Location Selection
Natural gas (methane): The detector should be installed approximately 30 cm from the ceiling (natural gas is less dense than air, so leaks tend to stay high).
Liquefied petroleum gas (propane): The detector can be installed approximately 30 cm from the floor (liquefied petroleum gas is more dense than air, so leaks tend to stay low).
Avoid directly above the stove to prevent interference from high temperatures or oil smoke.
Linkage valve: Select a gas shutoff valve that can be manually reset by the user.
5.Precautions
Explosion-Proof Certification: Gas stove areas must utilize equipment certified by international explosion-proof certifications such as ATEX and CE to minimize the risk of explosions caused by equipment failure.
Real-Time Monitoring: It is recommended to select equipment that supports signal transmission to facilitate real-time monitoring of gas concentration changes during stove operation.
Regular Maintenance: It is recommended to calibrate and clean the detector every six months or once a year to ensure sensor sensitivity and explosion-proof performance.
