Amphenol SGX Sensortech Solid Polymer Electrolyte Gas Sensors are designed to detect a wide range of gases, including Carbon Monoxide, Chlorine, and Volatile Organic Compounds (VOC), as well as humidity and particulates. The Solid Polymer Gas Sensors are based on the principle of electrochemical catalytic reaction. Thesensor responds to the target gas and delivers a very small current proportional to the gas concentration. The SGX Solid Polymer Sensors have a dry core design of three electrodes in contact with the solid electrolyte. A typical electrode consists of a surface area of precious metal and other materials. The electrode, electrolyte, and the surrounding air are in contact while the gas diffuses through the back of the porous membrane into the working electrode of the sensor. At this working electrode, the gas is oxidized or reduced.
