What is a Gas Sensor? Construction, Types & Working of Gas ...

04/06/2019· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated. MQ-6 Gas Sensor ...

Frequently Asked Questions about LEL Gas and LEL Gas ...

06/04/2020· As the amount of detectable combustible gas rises, an LEL sensor will display a readout from 0 - 100% LEL. For example: Methane has an LEL of % Vol in air. When the volume of Methane has reached % Vol, we've reached the 1/2 way point or 50% LEL. If volume continues to rise to % Vol, the gas monitor will display 100% LEL and combustion is imminent if conditions are right. An …
