Absolute and Relative Gas Concentration: Understanding ...

Like most gas sensors, the Apogee O2 sensor responds to the absolute concentration of O2 in air. Thus changes in pressure and temperature change the output of the sensor even though the relative concentration of O2 has not changed. Fortunately, the sensor responses to pressure and temperature (P and T) are repeatable, thus it is possible to measure P and T and correct for them in software ...

Why is hydrogen such a big issue for CO sensors? | GfG ...

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross sensitivity …

Gas Sensor - an overview | ScienceDirect Topics

Gas sensors are used for detecting a wide range of gaseous substances in the atmosphere, including pollutants, toxins and combustible gases. In the case of combustible gases, the sensing element is a platinum wire coated with a mixture of substances which catalyse the oxidation of the gases. The coil is heated by passing a current through it; this causes combustion to occur, generating additional heat …

BMW extends UK recall over fire risk – Which? News

14/10/2019· BMW is extending its recall of diesel cars, after it was found that faulty parts could lead to a potential fire risk. In 2018, BMW originally recalled 268,000 UK diesel cars after it was found that glycol leakage from the engine’s exhaust gas recirculation (EGR) cooler could result in burning soot deposits when combined with the high temperatures inside the EGR system.

Toxic Gas & Oxygen Detectors | Gas Sensors | RC Systems

A sensor inside the toxic gas detector reads the gas levels, and when they rise above or fall below the specified level, an alarm activates. Sensors are made from electrochemical cells, and the alarm can be visual or audible. Readings can be sent via a digital signal or analog signal to a control room, and alarms can actuate local relays for the operation of alarm safety devices such as horns, fans, valves, etc.
