MC105 Catalytic Combustion - type Flammable Gas Sensor For Detecting The Concentration Of Flammable Gases And Organic Solvent Vapors In Industrial Sites

Working Principle:

The sensor adopts the catalytic combustion principle and consists of a test element and a compensating element that form two arms of an electric bridge. When the test element comes into contact with flammable gases, its resistance increases. This causes a change in the output voltage of the bridge, and the voltage variation is directly proportional to the increase in the flammable gas concentration. The compensating element serves as a reference and plays a key role in compensating for the impacts of temperature and humidity changes on the detection results, ensuring the stability of the sensor in different environmental conditions.

Core Features:

1. Linear Output Performance: The bridge output voltage has a linear relationship with the concentration of flammable gases. This linear characteristic simplifies the subsequent signal processing and calculation for gas concentration, facilitating accurate quantitative detection.
2. Reliable Anti - interference Capability: It has excellent resistance to H₂S poisoning and organosilicon interference. This enables the sensor to maintain stable performance even in harsh industrial environments where such interfering substances may exist, avoiding false alarms or detection inaccuracies.
3. Fast Response and Stable Operation: With a response time of less than 10 seconds and a recovery time of less than 30 seconds, it can quickly detect changes in flammable gas concentrations and recover to the initial state promptly after the gas dissipates. Additionally, it has good repeatability and selectivity, and the annual drift of its output signal is less than ±2 mV, ensuring long - term detection reliability.
