Gas Sensors

AST’s gas sensors often combine several measurement principles into one sensor. For concentration/quality measurement, thermal conductivity is often measured but also optical systems are applied to determine properties of gases.

Examples of gas sensor applications include leak-/concentration detection in hydrogen-powered vehicles and air quality measurement in ventilation systems (HVAC). Generally our sensors are able to determine the properties of a variety of gases.

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

Vehicles with hydrogen drives require a safety concept at the highest level. In particular, the detection of a leak in the hydrogen supply is an essential element in the careful handling of the critical medium hydrogen. The Hydrogen sensor based on the TCS process with its robust measuring principle fulfills this requirement perfectly. It is characterized by its low cross-sensitivity to other gases and its long-term stability.

Air quality sensors permanently measure the intensity, degree of pollution, and number of odor molecules in the exhaust air. These measurements can then be used to adjust the fan performance levels and generate a pleasantly fresh atmosphere.

In addition, the continuous measurement of air pollution enables our smart sensors to predict when the filters will need to be replaced and when the unit will next require servicing.
