YJJ CH-A3 Catalytic Combustion Type Gas Sensor Is Used For Safe Gas Detection

Features:

CH-A3 gas sensor is a catalytic combustion type gas sensor produced by the British company Alphasense. It is mainly used for detecting the concentration of combustible gases, and is particularly suitable for scenarios such as oil drilling and extraction, and industrial safety.

Core parameters
Detection principle: Catalytic combustion type. Concentration is detected by the change in heat generated from the combustion of combustible gases on the catalyst surface.
Range: Supports 0~100% LEL (lower explosive limit), applicable to various combustible gases (such as methane, propane, etc.).
Response time: T90 (90% response time) is typically within 10 to 30 seconds, depending on the gas type and environmental conditions.
Accuracy: ±5% F.S. (full scale), some models support higher accuracy.
Operating temperature: -20℃~50℃ (standard type), wide temperature type can reach -40℃~70℃.
Protection level: IP66/IP67 (dust and water protection), compliant with ATEX, IECEx, etc. explosion-proof certifications. Purpose
Oil drilling and extraction: Monitoring the leakage of flammable gases in areas such as wellheads and storage tanks to prevent explosion risks.
Industrial Safety: Real-time gas concentration monitoring for use in chemical plants, gas stations, and other such facilities.
Environmental Monitoring: Measuring the pollution levels of flammable gases in the atmosphere to assist in environmental management.
Other characteristics
Anti-interference capability: Has cross-sensitivity to gases such as hydrogen sulfide and carbon monoxide. Careful calibration is required.
Communication interface: Supports 4G/5G, RS485, etc. for remote data transmission, facilitating integration into the IoT platform.
