A test system for gas sensors - ScienceDirect

Two test chambers have been developed, optimized for a small volume and a precisely defined gas stream. These test chambers simultaneously contain up to ten sensors of different types (semiconductor, dielectric, microbalance, etc.) and provide measurements of gas temperature and pressure. The exhaust gases are analysed by a dew-point mirror and an optional infrared gas analyser to check the gas combination and accuracy of gas concentration. Measurements with semiconductor sensors, …

Gas detection systems in automotive test chambers

Depending on the specification of the individual test chamber the temperature can vary between -40 °C and +90 °C. In many cases the humidity in the test chambers can vary from 5% up to 95% RH. These particular conditions often represent a major challenge for both the test objects and the gas warning devices. The changes in

TEST METHODOLOGIES FOR HYDROGEN SENSOR …

In chamber test methods, gas transport to the sensor can be dominated by diffusion which is viewed by some users as mimicking deployment in rooms and other confined spaces. Alternatively, in flow through methods, forced flow transports the gas to the sensing element. The advective flow dynamics may induce changes in the sensor behaviour relative to the quasi-quiescent condition that may ...
