Gas Sensors

AST's gas sensors often combine several measurement principles in one sensor. Thermal conductivity and thermal diffusivity measurements are often used for measuring concentrations/quality, but optical systems are also applied in the determination of gases.

Examples of our gas sensor applications are leakage and concentration measurement for hydrogen-powered vehicles or air quality measurement for the control of ventilation systems (HVAC). In general, our sensors can determine the properties of a wide range of different gases.

All AST sensors are equipped with a microcontroller and are thus able to calculate complex algorithms directly at the sensor. An output signal processed in this way is made available in analog or digital form.
