Constant monitoring of flammable gases and vapors is essential for a safe workplace. The Dräger PIR ® 7000 is an explosionproof point gas detection transmitter that uses infrared (IR) technology to continuously monitor ...
combustible gas may degrade sensor performance. INFRARED DETECTORS Gas sensing by the Infrared (IR) detection method is based upon the absorption of infrared radiation at specific wavelengths as it passes through a volume of gas. General Monitors’ IR detection technology incorporates a light source and a light detector that
The IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas. It monitors in both the LELm and ppmm ranges to detect both small and large leaks. The IR5500 offers the benefits of early detection with its high sensitivity to gas …
Nov 15, 2000· Recently evaluation of the system for gas detection has been performed. This paper presents these results. The system uses a conventional infrared camera fitted with a diffractive optic that images as well as disperses the incident radiation to form spectral images that are collected in band sequential mode.
Sep 20, 2018· Infrared Sensor (IR sensor) is the technology of choice for methane detection. A nondispersive infrared sensor (NDIR) typically consist of an IR source, a sample chamber, a light filter, and an IR detector. Typically, a second chamber containing a reference gas …
Thus, infrared radiation is essentially heat radiation. Read more: Reliable Gas Detection: The unique properties of the patented singlepulse infrared gas detector eliminate the need for frequent …

In order to detect a harmful gas in the air the multi gas detector brings gas in, sends it through a process with a sensor, and computes the amount of toxic gas in the air. The process and sensor vary depending on the type of detector and the gases being detected. The following are a few of the many types of gas detectors.
Infrared gas detection is based upon the ability of some gases to absorb IR radiation. Many hydrocarbons absorb IR at approximately micrometers and in this region H2O and CO2 are relatively transparent. As mentioned earlier, there are some hydrocarbons and other flammable gases that have poor or no response on a general purpose IR sensor.

Combustible, toxic, gas leak and oxygen depletion detectors for personnel, process and asset protection. DetTronics has designed and manufactured certified gas detection solutions for hazardous industrial environments for over 30 years. During this time, we have developed a broad line of innovative and reliable gas detectors…
A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
Infrared Gas Sensors I nfrared (IR) gas detection is a welldeveloped measurement technology. Infrared gas analyzers have a reputation for being complicated, cumbersome, and expensive. …
Thus, infrared radiation is essentially heat radiation. Read more: Reliable Gas Detection: The unique properties of the patented singlepulse infrared gas detector eliminate the need for frequent recalibrations and problems with long term drift. And does so with greatly improved sensitivity, resolution and time response.
Jul 29, 2011· However, these sensors are still exposed to the environment and hazards of everyday use on the job and therefore are susceptible to having the gas pathway to the sensor blocked by dirt and debris. If gas cannot enter the sensor, it cannot be detected. The characteristics of the light source and the IR detector may also be changed due to damage ...
The IR light source emits a broad spectrum of infrared light at all wavelengths which travels from the source to the sensor. On the way some wavelengths are absorbed by the gas molecules of interest. At the detector the difference in light intensity between no absorption and gas specific absorption is measured to determine the actual gas ...
