Optional LEL Latching Alarm - Blackline Safety

When LEL latching alarm is enabled, the G7 will not stop alarming when LEL sensor readings return from the high alarm threshold. The device user must manually cancel the alarm by pressing and holding on the G7’s up and down arrow buttons for three seconds. If the LEL gas alarm is not canceled by the device user, it will continue until the battery is depleted.

Everything You Wanted to Know About Multigas Detectors!

Combustible gas detectors usually provide readouts in % of LEL (Lower Explosive Limit), in the 0 to 100% range. The lowest concentration, in air, of ignitable vapours corresponds to 100% of the LEL. Therefore, a combustible gas which has a LEL of 100% at 4% volume in air would produce a readout of 50% of the LEL if only 2% of the volume of air is that gas. The most popular sensor is the ...

Frequently Asked Questions about LEL Gas and LEL Gas Detectors

2020-04-06· For example: If an LEL sensor is calibrated with Methane gas, but the target gas is known to be pentane which has a lower LEL of % Vol, then actual %LEL could be double. Gas monitor displays 50%LEL, but is actually closer to 100%LEL due to it being a different target gas. Manufacturers do have published charts detailing correction factors to adjust readout for specific gasses. As a rule of ...

Definition of LEL - Lower Explosive Limit

In gas detection systems the amount of gas present is specified as a percentage (%) of LEL. Zero percent Lower Explosive Limit (0% LEL) denotes a combustible gas-free atmosphere. One hundred percent lower explosive limit (100% 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 …

Infrared LEL Gas Sensors – Risk or Reward?

2017-08-07· The detection capability of the IR sensor is limited by the adsorption characteristics of the targeted gas and the bandwidth of the filter in the sensor. Many combustible gases are simply undetectable by these low power infrared LEL gas sensors. Examples of non-detectable combustible gases include acetylene, acrylonitrile, aniline, and carbon disulfide. Again, manufacturers will …
