Winsen MC119 Catalytic Flammable Gas Sensor

The Winsen MC119 sensor operates on the catalytic combustion principle. It features two arms of an electric bridge, which includes a test element and a compensate element. The resistance of the test element increases when exposed to combustible gases, causing a change in the output voltage of the bridge. This voltage variation is directly proportional to the gas concentration. The compensate element helps in compensating for temperature and humidity effects.

• Avoid High Concentration Exposure: Do not expose the sensor to gas concentrations outside the 0-100% LEL range to prevent sensor damage.,
• Prevent Exposure To Extreme Conditions: Avoid using or storing the sensor in environments outside the specified temperature and humidity ranges.

• Ensure Correct Voltage: Operate the sensor at the specified voltage of 2.5±0.1 V to ensure accurate functioning.,
• Check Compatibility: Use the sensor within its specified gas detection range and environmental conditions.

• Voltage: 2.5±0.1 V,
• Current: 100±10 mA

• Temperature Range: -40 to +70°C for operation, -20 to +70°C for storage,
• Humidity: Less than 95% RH, non-condensing

• Description: Integrate the sensor with a simple drive circuit. Ensure that the bridge output is connected correctly to interpret the voltage variations corresponding to gas concentrations.
