Ammonia Sensing and a Cross Sensitivity Evaluation with ...

The optical sensor for ammonia shows its capabilities to detect 100 ppm ammonia in the deep UV region based on the absorption lines are similar to the theoretical spectrum. The cross sensitivity with CO 2 and O 2 gas has also been tested and it clearly shows that these two gases have no impact on the NH 3 measurement in the region of 200-230 nm. Thus, it has been demonstrated that the UV range ...

MOS sensors can be used to detect ammonia from concentrations as low as 30 ppm, all the way up to flammable range concentrations. However, because the output signal is highly non-linear, they need to be calibrated and adjusted for use in the desired range. Adjustment for use

Ammonia-sensitive sensor for ammonia measurements in ...

This sensor can be used to measure ammonia (NH3) in aqueous solutions. In an aqueous solution, ammonia is in a pH-dependent equilibrium with ammonium ions (NH 4 + ions). Provided the NH4 + ions are converted into ammonia by adding lye, the sensor also detects the resultant ammonia. The NH4 + ions themselves are not detected. The ammonia sensor consists of a pH glass electrode and a …

Sensor placement guide | Opera Inc.

Resources/ Sensor Placement Coverage . Guidelines for sensor placement of diffusion type sensors are based on the reasonable delay for gas to get from the source to the sensor. All sensors are created equal in this regard. For air quality control of exhaust emissions and accumulations of toxic gases the generally acceptable maximum radius of coverage is 50 feet (15 meters). Approximately 7500 ...

Ammonia sensors and their applications—a review

3. Application areas of ammonia sensors There are many ways to detect ammonia. High concentra-tions are easy to detect because the gas has a very penetrat-ing odour. With respect to other odorous gasses, the human nose is very sensitive to ammonia. To quantify the ammonia concentration or determine lower concentrations of ammo-nia, the human nose fails. However, in many occasions, the
