Electrochemical high-temperature gas sensors

SPIE Proceedings, 2012
Combustion produced common air pollutant, NOx associates with greenhouse effects. Its high temperature detection is essential for protection of nature. Component-integration capable high-temperature sensors enable the control of combustion products.

Self-calibrating electrochemical gas sensor

Proceedings of International Solid State Sensors and Actuators Conference (Transducers '97), 2002
A self-calibrating electrochemical gas sensor with an online supervision of the gas sensor's function, sensor's sensitivity and sensor's response time is presented. It leads to an online electrical recalibration and an early detection of an aging dependant sensor failure by detection of the value of sensor's electrochemical active area.

Solid-state electrochemical gas sensors

Ionics, 2009
The solid-state electrochemical principle has been a selective and accurate way of sensing chemical components in various environments, including liquid metal, for an extended period of time. Since after Carl Wagner’s interpretation of zirconia, there appeared many advances in chemical sensor applications.

Electrochemical sensors for environmental gas analysis

Current Opinion in Electrochemistry, 2020
Abstract The application of electrochemical sensors for measurement of concentration of pollutant gases in air in the part-per-billion (109) range is reviewed. Performance-limiting factors, particularly the effects of extremes and of relatively rapid changes in ambient temperature and humidity, are noted.

Solid State Electrochemical Chlorine Gas Sensor

Berichte der Bunsengesellschaft für physikalische Chemie, 1990
AbstractA solid state sensor for monitoring chlorine is presented. The applied method is the potentiometric partial pressure measurement via heterogeneous secondary equilibria using an appropriate solid state galvanic cell. The sensor is a planar double cell mounted on a supporting ceramic carrier.

Thin solid state electrochemical gas sensors

Sensors and Actuators, 1981
A new family of electrochemical gas sensors based on the use of thin and thick film technologies has been under study in our Laboratory for some years. This microelectronics approach allowed us to design solid state devices for oxygen and hydrogen detection.

Theory of gas sensors: response of an electrochemical sensor to multi-component gas mixtures

Sensors and Actuators B: Chemical, 1996
A first-principles model of the operation of an electrochemical metal oxide gas sensor had been previously used to analyze the response when the sensor was exposed to a simple gas mixture (e.g. O 2 /CO/CO 2 ). Here, the model is extended to study the sensor response to a complex gas mixture containing two reducing gases e.g.

Solid-state electrochemical gas sensors

Sensors and Actuators, 1987
Abstract The basic principles of operation of gas sensors based on solid-state galvanic cells are described. The generation of potentials and currents as a function of the partial gas pressures is considered for three types of solid electrochemical sensors: (i) direct measurement of the mobile species; (ii) indirect measurement of immobile components;
