The LEL sensor reads a percentage of the LEL from zero percent–100 percent, in 1 percent increments. Five percent methane equals 50,000 ppm, ...

The residual O 2 in the instrument and sensor allows the LEL sensor to still read as high as 2.16% vol before it starts to drop, due to the lack of oxygen in the chemical reaction.

A pentane-calibrated catalytic bead LEL sensor will read high because the correlation factor is 0.5. On the other hand, a propane-calibrated infrared LEL sensor will read low at 3 percent LEL.

This innovative handheld device features real-time monitoring with audible, visual (bright LED) and vibrating alarms, ...

The IR400 Infrared (IR) Point Detector from MSA is a hydrocarbon gas detector that constantly monitors combustible gases and vapors within the lower explosive limit (LEL) and delivers alarm indication ...

This concentration certainly is high enough to change the thermal conductivity of the atmosphere and produce a change on the LEL sensor. In this situation, you also should note that because of the ...

Teledyne Gas & Flame Detection is supporting its business presence in the Middle East by partnering with Industrial Detection ...

Teledyne GFD’s FP-700 is also a non-intrusive ‘smart’ sensor, this time for the detection and monitoring of combustible gases over the range of 0-100% LEL using catalytic bead sensor technology.
