How does a line-of-sight gas detector work?

InfraRed detectors use the infrared absorption of hydrocarbon gases in the 3.4 micrometers wavelength to detect when a combustible gas is present. These detectors utilize an infrared light transmitter to detector at the target gas wavelength as well as control the wavelength.

What is LFL M?

Fixed point flammable gas detectors measure concentrations in percent of the Lower Explosive or Flammable Level (%LFL). Open path devices measure in LFL over distance in meters (LFL. m) e.g. A 5 meter gas cloud with a concentration of 50% LFL will read 2.5 LFL.

How many types of gas detector are there?

Gas detectors come packaged into two main form factors: portable devices and fixed gas detectors. Portable detectors are used to monitor the atmosphere around personnel and are either hand-held or worn on clothing or on a belt/harness. These gas detectors are usually battery operated.

Is LFL and LEL the same?

Below the lower flammable limit (LFL) the mixture of substance and air lacks sufficient fuel (substance) to burn. This is sometimes called the lower explosive limit (LEL).

How accurate are gas leak detectors?

PPM stands for parts per million. The lowest reading, 40 ppm, means that the leak detector is sensing 0.004% natural gas. This is a very small leak. At the top end of the scale, you’ve got 640 ppm, which would be 0.064% natural gas – a leak you should worry about.

What is Det-Tronics opecl open path IR gas detector?

The Det-Tronics OPECL Open Path IR Gas Detector is suited for Open Path Gas Detection applications in oil, gas, and petrochemical facilities. The Det-Tronics OPECL Open Path IR Gas Detector.

Why choose Det-Tronics point gas detectors?

You can count on Det-Tronics to engineer and deliver point gas detectors with field-proven performance and minimal maintenance/calibration requirements for your combustible gas detection needs. Continuously monitors for hydrocarbon gas clouds in large open areas up to 120 meters.

Why choose Det-Tronics fire and gas safety systems?

Our field-proven toxic gas and oxygen depletion detection solutions deliver protection for both people and processes. Det-Tronics offers certified fire and gas safety systems in a variety of configurations to meet the most demanding certification and listing requirements.

Why choose line-of-sight gas detectors?

Detecting hydrocarbon and non-hydrocarbon combustible gases before an issue develops is a demanding application requiring approved, robust and reliable technology that works every time, without fail. Line-of-sight detectors are an excellent choice for protecting wide open spaces, especially along facility perimeters.
