Electronic Circuits for Use in Electrochemical Gas Sensors

Mar 10, 2015· This article is a guide to the design of electronic circuits used with SGX Sensortech electrochemical gas sensors. The block diagram of a typical gas detection system with an electrochemical gas sensor is shown in Figure 1. The gas sensor operates using a bias circuit for maintaining the appropriate bias potential between the sensing and reference electrodes.
