Cross sensitivity of toxic sensors: Chris investigates the ...

· A CO sensor which has a positive response to H 2 at a rate of 60%. Therefore, if the CO sensor saw 200ppm of H 2 then the CO sensor will show around 120ppm ( 60% of 200ppm). Negative response A negative response is when sensors produce a reduced response to the target gas if also exposed to a gas that causes a negative response. If this happens, the user may be exposed to …

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

The following chart shows the response of an LEL sensor and a 2CF “hydrogen nulled” CO sensor to 10% LEL methanol (= 6,000 ppm). Note that this is a very high concentration of methanol! In the following chart you can see when the methanol starts to break through the internal filter in the CO sensor. The CO reading does not begin to rise until almost minutes after the methanol exposure ...

Detection of Li-ion battery failure and venting with ...

· Finally, CO 2 is found in the cell leakage gas, so a CO 2 sensor can be used to detect a slow leakage. Carbon Monoxide (CO): CO was found in large amounts in the vent-gas of battery abuse tests. However, the concentration of CO decreased for cells with lower SOC and in the LFP cell thermal runaway case , so CO is considered inconsistent regarding detection. For first venting events, some ...

Leakage Current Measurement Reference Design for ...

The leakage current is measured by applying a fixed voltage and measuring the voltage across the shunt that is a result of the leakage current. The reference design uses different switchable shunt resistances, which are switched on in a sequence to measure the insulation resistance. When there is a dead short, the insulation resistance is 0 Ωand a full current (or maximum) can pass through ...
