Gas detector - Wikipedia

Semiconductor sensors, also known as metal-oxide-semiconductor sensors (MOS sensors), detect gases by a chemical reaction that takes place when the gas comes in direct contact with the sensor. Tin dioxide is the most common material used in semiconductor sensors, [10] and the electrical resistance in the sensor is decreased when it comes in contact with the monitored gas.

Gas Pressure Sensors | The Design Engineer's Guide | Avnet ...

A sealed gas pressure sensor is similar to a gauge gas pressure sensor but has been pre-calibrated to measure gas pressure in relation to sea-level atmospheric pressure. So its readings won’t change if the unit is taken to a different altitude or location. Vacuum pressure is the measure of the negative difference between the gas pressure at a given location and atmospheric pressure. Absolute ...
