  • Multiple sensor fault detection and isolation of an air quality monitoring network using RBF-NLPCA model

    This paper presents a data-driven method based on non-linear principal component analysis to detect and isolate multiple sensor faults. The RBF-NLPCA model is obtained by combining a principal curve algorithm and two three-layer radial basis function (RBF) networks. The reconstruction approach for multiple sensors is proposed in the non-linear case and successfully applied for multiple sensor ...

  • Fault detection and isolation of sensors in aeration control systems

    In this paper, we consider the problem of fault detection (FD) and isolation in the aeration system of an activated sludge process. For this study, the dissolved oxygen in each aerated zone is assumed to be controlled automatically. As the basis for an FD method we use the ratio of air flow rates into different zones. The method is evaluated in two scenarios: using the Benchmark Simulation ...

  • Safe Landings Whatever the Weather: Lufft Sensors on Airports

    Pilots, air traffic controllers and airport operators do their best to make air travel safer and more efficient. Sometimes, however, flight security depends on external factors we can hardly influence. This especially refers to risky weather conditions: Strong winds, icy cold or strong precipitation can have serious consequences. On average, 23% of all aircraft accidents and 68% of canceled ...

  • Instrument air case study

    Application Moisture is measured in instrument air to ensure that the air is properly dried. Problem Instrument air is used through-out a facility to protect delicate electronics, instruments, and to operate key process actuators. Many instruments also use instrument air to operate various pneumatic operators they might possess. Too frequently, there is ...

  • Indoor Air Quality Myths Debunked

    Today’s buildings, whether it is a home, office, manufacturing plant, hospital, etc., are more energy efficient; however, they also foster a potentially harmful environment. Indoor Air Quality (IAQ) has become a rising concern in the HVAC industry. Poor IAQ can cause a number of health issues such as, allergies, dryness and irritation to the eyes, nose, throat, and skin. It can also cause ...

  • CO2 vs. VOC Sensors for IAQ - What`s the Difference

    People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...
