carbon monoxide sensor cross sensitivities

Using Electrochemical Gas Sensors for Detection of Carbon ...

· Each sensor datasheet describes the levels of cross-sensitivity in detail. The sensor’s zero signal and the net sensitivity to the target gas are affected when the ambient temperature changes. The electrodes employed in SGX sensors have been designed to mitigate these temperature effects as much as possible. However, some effects will still ...

Carbon Monoxide and Sensory Sensitivity

· Carbon monoxide (CO) is the most common cause of toxic poisonings and deaths in America, and has been for over a century. CO also may be the most common cause of MCS, but it causes a very specific type of MCS that we call Multi-Sensory Sensitivity or MUSES Syndrome. MUSES Syndrome is caused only by CO poisoning and is characterized not just by hypersensitivity to …

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

· Cross sensitivity is a sensor’s reac­tion to other gases which can “interfere” with how the sensor reacts. Exposing a sensor to a gas that is not the target gas can cause an undesirable effect; this may be a positive response, negative response or inhibition. Positive Response A positive response means that sensors respond to not just the target gas but to another gas as well. This ...
