FAQs Gas Detectors | Gas Sensors by RKI Instruments

Gas Detection Sensor Mounting Height and Location Guidelines: It is important to mount the gas detection heads in areas that are most likely to first be exposed to a gas leak, or that are most representative of the gas levels in the area being monitored. Here are some criteria to consider: Density of the gas: When detecting for LEL levels of gases and vapors, the density of the gas should be ...

Portable Gas Detectors for Landfill Gases

of methane and carbon dioxide, as well as potentially lethal concentrations of hydrogen sulphide. ‘Wheatstone Bridge’ type LEL sensors detect gas by catalytically oxidizing or ‘burning’ the gas on an active bead or ‘pellistor’ located within the sensor. The ‘active’ bead is treated with a platinum or

AP 1018: Understanding catalytic LEL combustible gas ...

Figure 4: Catalytic “Pellistor” LEL sensors detect combustible gas by catalytic oxidation. When exposed to gas the oxidation reaction causes the “active” bead to heat to a higher temperature. Pellistor LEL sensors require oxygen to detect gas! Figure 5: The active “Pellistor” bead is strung onto a coiled platinum filament wire.

Why Is Methane Used as A Calibration Gas? | Newcastle ...

Jun 22, 2020· Calibration gas is a reference gas used to ensure accurate readings on gas detectors and instruments. The calibration process involves exposing the sensor to a certified concentration of gas for a particular length of time. The calibration gas you use to calibrate your LEL gas detection device is first based upon your application.

What does "methane %LEL equivalent" mean?

Low Alarm (%LEL) = 10 (based on CH4) High Alarm (%LEL) = 20 (based on CH4) UEL is the Upper Explosive Limit at which a gas concentration is too high it is not explosive. However, for safety purposes, we use only the LEL. A catalytic sensor is 0100% LEL, which means it is 05% vol. (or 50,000 ppm) equivalent to Methane.
