Product Description:

YJJ CAT16 CAT-16 Catalytic Combustion Sensor Is Used Detect Concentration Of Combustible Gases

Features:

Core parameters
‌Detection principle‌: Utilizes catalytic combustion sensors, capable of detecting combustible gases such as methane, propane, and hydrogen.
Range: 0 - 100% LEL (Lower Explosive Limit), response time less than 15 seconds.
Working environment: Temperature -40℃ to 50℃, humidity 0-95% RH (no condensation), supports explosion-proof structure.

Output mode: Analog signal output, supporting 4-20mA current output.
Main application
‌Industrial/Commercial Environment Monitoring‌: Suitable for monitoring of combustible gases such as natural gas and liquefied gas, including in places like chemical plants and gas stations. ‌
Safety protection: It can be connected to an audible and visual alarm system. When the concentration of combustible gas exceeds the limit, the alarm will be triggered.
Home application scenario: Some models are suitable for home use, such as gas leakage detection in environments like kitchens.
This sensor needs to be installed with the help of a dedicated PCB socket to prevent damage to the equipment during soldering
