  • Fast detection of hazardous organic gases in the ambient air using adaptive neuro-fuzzy inference systems

    In this study, an adaptive neuro-fuzzy inference system (ANFIS) is proposed for the concentration estimation of volatile organic gases before the sensor response time by using the transient sensor response. A neural network (NN) structure with tapped time delays and Mamdani's fuzzy inference system (FIS) are also used for comparison. The estimation results of ANFIS are better than those of the ...

  • Characterisation of aseptic sterilisation processes using an electronic nose

    The present work describes the development of a multi–sensor system for the evaluation of aseptic sterilisation processes employing hydrogen peroxide vapour by means of an electronic nose. Microbiological count reduction tests with Bacillus atrophaeus spores have been carried out in order to characterise influencing factors of the sterilisation by hydrogen peroxide vapour, namely the hydrogen ...

  • BUMP TESTING AMMONIA (NH3) SENSORS

    Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (1-2 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall ...

  • Model 5100 Verification/Validation case study

    Background Many sensors used in gas analyzer systems come into direct contact with the process gas, and there is the potential for degradation over time especially with streams that contain contaminants like glycol, moderate to high levels of hydrogen sulfide etc. With sensor degradation, the analyzer response characteristics change resulting in inaccurate readings. In order to ...

  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • Filter damage monitoring in clean gas side - Case Study

    Application A coffee producer fi nishes coffee beans. During the handling process the beans are cleaned with water inside a tank. After cleaning, the beans are dried in another tank with heat. The moist air that results from this process is extracted by a vacuum, fi ltered and returned to the heat exchanger. The cleaning of the exhaust air is done by fi lter ...
