Nexisense GTYQ-MIC-600 Fixed Multi-Gas Detection Alarm Product Definition & ApplicationFields
The Nexisense GTYQ-MIC-600 Fixed Multi-Gas Detection Alarm is a high-precision, multi-functional gas detectionalarm designed for continuous online monitoring of hazardous gases such as CO, H2S,O2, and combustible gases. It is widely used in petroleum, chemical, power, pharmaceutical, and environmental industries to ensure operational safety.
Capable of detecting upto six gases simultaneously, it features high-resolution sensors, real-time alarms, and multiple communicationprotocols including RS485, 4–20 mA, and wireless transmission.
Typical Applications:
Petrochemical plants: Prevent explosionsand poisoning by monitoring gas leaks
Pharmaceutical & food industry: Ensure cleanroomstandards
Environmental monitoring: Track pollutant emissions
Industrial safety: Monitor confinedspaces, storage areas, or hazardous sites
Detection Principles
The Nexisense GTYQ-MIC-600 Fixed Multi-Gas Detection Alarm supports various sensing technologies depending on the gas type:
Electrochemical: Detects gases like CO, H2S, O2 via electrode reactions generating measurable current/voltage.
Infrared (NDIR): Uses gas-specific IR absorption to detect gases such as CO2 and hydrocarbons.
Catalytic Combustion: Measures heatreleased from gas oxidation on catalysts, ideal for flammable gases.
Thermal Conductivity: Measures differences in heat conduction to detect gases like H2 and He.
PID (Photoionization): Ionizes VOCs underUV light and measures resulting currents, suitable for benzene, toluene, etc.
Structural Design
The Nexisense GTYQ-MIC-600 Fixed Multi-Gas Detection Alarm features a rugged, explosion-proofenclosure certified to ExdⅡCT6 standards, built from corrosion-resistant materials for harsh environments. The internal architecture includes multiplegas sensors, digital processing circuits, and a high-resolution display for real-time readings.
