Let’s explore the key gas detection technologies and how they work:

Catalytic Sensors

Catalytic sensors are commonly used to detect combustible gases. These sensors consist of a catalytic material that reacts with gas molecules, leading to a rise in temperature. The change in temperature is measured by the sensor, and if it exceeds a certain threshold, an alarm is triggered. Catalytic sensors are highly responsive and can detect a wide range of flammable gases such as methane, propane, and hydrogen.

Infrared Sensors

Infrared sensors are another popular technology used in combustible gas detectors. These sensors rely on the principle of absorption of infrared radiation by gas molecules. When a specific gas is present, it absorbs a certain wavelength of infrared radiation, causing a reduction in the intensity of the received signal. Infrared sensors detect changes in the infrared radiation and generate an alarm when the gas concentration exceeds a predefined level. They are commonly used to detect hydrocarbon gases such as methane, ethane, and butane.

Electrochemical Sensors

Electrochemical sensors are designed to detect toxic gases like carbon monoxide and hydrogen sulfide. These sensors utilize chemical reactions that occur at the surface of an electrode. The gas molecules interact with the electrode, causing a change in current flow. The magnitude of the current change is proportional to the gas concentration, and when it reaches a certain threshold, the alarm is activated. Electrochemical sensors provide accurate and reliable detection of toxic gases and are commonly used in industrial settings and residential areas.

Metal Oxide Semiconductors

Metal oxide semiconductors are versatile sensors used for detecting a wide range of gases, including combustible and toxic gases. These sensors operate based on the principle of changes in electrical conductivity when exposed to gases. When a target gas is present, it interacts with the metal oxide surface, altering the conductivity of the sensor. By measuring the changes in electrical resistance, the gas detector determines the gas concentration and triggers an alarm when necessary. Metal oxide semiconductor sensors are sensitive, responsive, and cost-effective, making them ideal for various applications.
