Ceramic chemical sensors an overview.

Chemical sensors are measurement devices that convert a chemical or physical property of a specific analyte into a measurable signal whose magnitude is normally proportional to the concentration of the analyte. Coorstek sensors was formed to develop manufacture and deliver unique ceramic based smart sensors to help improve the environment around us combining the unique technologies of emisense emission sensors and pegasor air quality monitors for continuous real time on board and stationary monitoring. Chemical sensing principles methods and applications. Electrostatic potential drops across interfaces caused by the exchange of ions together with electrons may be used in various ways to measure the concentration of chemical species.

Some porous electrodes require two mode distributions of pore sizes. Ceramic components for all kinds of sensors from ultra sensitive pressure and temperature sensors to oxygen and chemical sensors coorstek provides high performance ceramic components for world class performance in virtually any service condition or application including sensor elements and components for. The general bibliography on chemical sensing contains a more complete exposition this chapter develops a taxonomy for this broad sensor class describes some promising application areas e g the detection of toxic chemicals in the environment and highlights the key materials challenges. Many electrodes used in electro chemical devices including gas purifiers gas sensors fuel cells and chemical analyzers are porous ceramics.

Small pores are for the electro chemical reactions while large ones are for flow paths of reactants.
