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

· Gas Sensor Working. The ability of a Gas sensor to detect gases depends on the chemiresister to conduct current. The most commonly used chemiresistor is Tin Dioxide (SnO2) which is an n-type semiconductor that has free electrons (also called as donor). Normally the atmosphere will contain more oxygen than combustible gases. The oxygen particles ...

Understanding Combustible Sensor Performance

A combustible gas sensor may be calibrated to any number of different gases or vapors. Where possible, the user should calibrate the instrument to achieve the level of sensitivity required for the substances to be measured. EnviroMed Detection Services 26 Glencoe Dr., Mt. Prearl, NL A1N 4S8 709-368-9000 4 Calibration is a two-step procedure. In the first step the instrument is ...

Combustible Gases | Catalytic and Infrared Sensors ...

Systems Combustible Gas Detectors feature both the Catalytic Bead and Infared Sensors. Catalytic Bead Sensors. The Catalytic Bead ("catbead" or "pellistor") sensor consist of a "reference bead" and an "analytic bead" wired into a Wheatstone bridge circuit. Catbeads burn a small amount of gas on the analytic bead which causes it to get hotter, increasing the resistance and voltage drop ...

Chapter 3 Catalytic Combustible Gas Sensors

Chapter 3 Catalytic Combustible Gas Sensors Chapter 3 Catalytic Combustible Gas Sensors C atalytic bead sensors are used primarily to de-tect combustible gases. They have been in use for more than 50 years. Initially, these sensors were used for monitoring gas in coal mines, where they replaced canaries that had been used for a long period of time. The sensor itself is quite simple in design ...

CORRECTION FACTORS FOR COMBUSTIBLE GAS (LEL) SENSORS

variety of combustible gases and vapors that exhibit different responses. Because LEL sensors use a diffusion barrier to limit the gas flux to the catalytic bead, they tend to have the greatest sensitivity to high-diffusivity compounds. Therefore, they are substantially more sensitive to small molecules like hydrogen and methane than to heavy components like kerosene. The best way to calibrate ...
