Definition of LEL Lower Explosive Limit Honeywell

One hundred percent lower explosive limit ( LEL) denotes an atmosphere in which gas is at its lower flammable limit. The relationship between percent LEL and percent by volume differs from gas to gas. The example below demonstrates the flammability of Methane (Natural Gas) in Air. In concentrations of 05% Methane in air, the mixture is too lean to ignite or burn. Methane concentrations ...

20210816· The XCD catalytic sensor can be used to detect flammable gases in the range 0 to LEL while the infrared (IR) sensor versions are available for the detection of methane in the range 0 to LEL, propane (with crosssensitivities to ethylene and butane) and Carbon Dioxide (CO2) in the range 0 to %v/v. Both sensors are used in conjunction with the flammable version of the …


Application Note 219 Using PIDs For 10% Of LEL ... Honeywell

below 10% of LEL (lower explosive limit). The most common sensor used for measuring LEL is the Wheatstone bridge/catalytic bead/ pellistor sensor (“Catalytic bead”). While useful in a wide variety of applications, in some settings catalytic bead LEL sensors either don’t have enough sensitivity to a particular chemical, or chemicals used in the environment can render the catalytic bead ...

CORRECTION FACTORS FOR COMBUSTIBLE GAS (LEL) SENSORS (FOR EMEA ONLY) Note: Changes have been made to the European Standard that defines the LEL (lower explosive limit) values for flammable gases. European Standard EN50054 defining the LEL values used in Europe has been withdrawn and superseded by a new standard, EN61779. The LEL …


Equivalent Gas Mixtures Honeywell Analytics

LEL sensors, which have been poisoned by silicone. Honeywell Analytics also offers methane calibration gas mixtures based on the actual percentage of LEL methane. Remember that in actual practice, the relative response varies somewhat from sensor to sensor. Response ratios may also shift over the life of a particular sensor. Most importantly, if sensitivity is lost due to poisoning, it is fre ...

COMBUSTIBLE GAS SENSORS The Sensepoint gas sensor for combustible gases is a sealed disposable sensor for the detection of flammable gases and is designed for industrial use with an approved junction box. The sensor is a certified product that can be used in atmospheres that will potentially contain


What gases can the LEL sensor detect? Honeywell

The LEL Catalytic sensor reacts with almost all inflamable gases. A new unit is factory calibrated for CH4 but the sensor can be calibrated for any other inflamable gas or adjusted through a correction factor. The IR LEL sensor is designed primarily for a target gas ( Methane, Propane). It can detect a variety of gases with a greater or ...


CORRECTION FACTORS FOR COMBUSTIBLE GAS (LEL) SENSORS

LEL sensors require oxygen for combustion and cannot be used in environments that contain less than 10 vol% oxygen. This threshold is the safe limit for up to LEL of nearly all chemicals, but it depends on the combustible gas concentration. For example, for 10% LEL Methane, RAE Systems LEL sensors show little or no oxygen dependence down to about 5 vol% oxygen. Inserting an LEL sensor ...


Sensepoint Flammable and Toxic Gas Detector | Honeywell

The flammable detector is available in either % LEL or PPM detection range versions and provides an industry standard mV bridge output. Typical life expectancy is greater than 5 years, after which the detector is simply replaced with a new one. The toxic detectors are supplied pre calibrated for easy installation and provide an industry standard 2 wire 420mA loop output. User connections are ...


RAE: Will the LEL sensor pickup Diesel Fuel? Honeywell
