which co sensor cross sensitivity

SPEC SensorTM

· an approximate 50% cross-sensitivity on the CO sensor; while CO exhibits virtually no response on the NO sensor. By including an NO sensor in the detector, the CO readings can be automatically compensated for the measured NO. ii. Applications where it is desired to measure two or more gases for which both sensors exhibit cross-sensitivity to the other gas. Example: measuring …

What is cross-axis sensitivity? | Murata Manufacturing Co ...

Cross-axis sensitivity is the maximum sensitivity in the plane perpendicular to the measuring direction relative to the sensitivity in the measuring direction. It is calculated as the geometric sum of the sensitivities in two perpendicular directions (Sx and Sy) in this plane. We appreciate your cooperation with the FAQ improvement questionnaire.

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

· Cross sensitivity responses will vary from sensor type to sensor type, and suppliers often express the cross sensitivity in percentages while others will specify in actual parts-per-million (ppm) levels. 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 …

Does the CO sensor have a cross-sensitivity to H2?

The electrochemical CO sensors used in the majority of our products do have a cross-sensitivity to elemental hydrogen (H 2) gas, with the precise degree of cross-sensitivity depending on the model in question. For those applications where the CO monitoring is necessary in the presence of H2, models with CO-H sensor would be the best option.

How to select the right CO sensors for your application ...

· The CO/H2 low sensor achieves this reduced cross-interference of hydrogen using two electrodes and a special catalyst with a lower sensitivity to hydrogen. The CO/H2 null sensor uses four electrodes and is actually a combination sensor (similar to the COSH sensor). It includes one sensing electrode dedicated to detecting CO and a second sensing electrode dedicated to detecting H2. The CO…

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

Sometimes the cross sensitivity is presented as an advantage to customers. In some cases the response is so high the manufacturer tells customers the sensors should not be used at all in the presence of hydrogen. GfG instruments can be equipped with a number of different models and types of single and dual channel CO sensors. For applications where hydrogen may be present we use …
