17/1/2013· A gassensor based on tunnelfieldeffecttransistor (TFET) is proposed that leverages the unique current injection mechanism in the form of quantummechanical bandtoband tunneling to achieve substantially improved performance compared to conventional metaloxidesemiconductor fieldeffecttransistors (MOSFETs) for detection of gas species under ambient conditions.

27/2/2020· Monitoring Carbon Monoxide Gas Levels in Tunnels. Carbon Monoxide is detected using an electrochemical gas sensor. This sensor measures the concentration of CO by oxidising it at an electrode and then measuring the resulting current. To reduce crosssensitivity to other combustible gases, it has chemical filters for H 2 S, N0 2, NO and SO 2.

Tunnel Sensors The VICONOX tunnel monitor is a single sensor solution for measuring NO 2 , NO, CO, visibility and temperature within a traffic tunnel, rail tunnel or other confined space. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection.
