These devices primarily rely on one of several detection methods, each nuanced towards specific operational contexts and sensitivity requirements. Understanding these core principles is essential for selecting the right type of natural gas detector for a given environment.

Catalytic Combustion Sensors

One of the oldest but still widely used technologies in natural gas detection. Catalytic combustion sensors measure gas concentrations through the heat produced when the gas burns, initiating a change in electrical resistance within the sensor. This change is proportional to the concentration of gas present, offering a reliable means of detecting natural gas leaks. However, these sensors require oxygen to function and can be poisoned by certain substances, limiting their use in certain industrial environments.

Infrared Sensors

Infrared (IR) sensors offer a non-contact method of detecting natural gas and other hydrocarbons. By emitting an infrared light into a monitored area, the sensor can detect specific wavelengths absorbed by natural gas molecules, thus determining the gas’s presence. One of the key advantages is their immunity to sensor poisoning and a lack of need for oxygen, making them ideal for a variety of environments. These sensors are particularly valued in the oil and gas industry for their durability and long service life.

Semiconductor Sensors

Utilizing a more modern approach, semiconductor sensors detect gases through changes in the electrical conductivity of a semiconductor layer when exposed to a gas. These sensors are sensitive to a wide range of gases, including natural gas. They are known for their rapid response times and are commonly used in portable gas detectors due to their compact size and lower cost. However, environmental factors such as humidity and temperature can affect their performance.

Electrochemical Sensors

For environments requiring the detection of low levels of natural gas, electrochemical sensors are often employed.

Types of Natural Gas Sensors

When it comes to ensuring safety in environments where natural gas could pose a risk, understanding the types of sensors available for detecting natural gas is crucial. There are primarily two types of natural gas detectors used in the industry: catalytic sensors and infrared sensors. Each type employs a different method for detecting natural gas and comes with its own set of advantages and applications.

Catalytic Sensors

Catalytic sensors, also known as combustible gas sensors, use a catalyst to oxidize natural gas, measuring the resulting heat to determine the concentration of gas in the air. When natural gas comes into contact with the catalytic surface, it heats up, altering the resistance in the sensor circuit and triggering an alarm. These sensors are widely used because of their sensitivity and reliability. They are particularly effective in environments where gas concentrations can reach levels high enough to combust, such as in petrochemical processing plants or natural gas pipelines. However, they require regular calibration and maintenance to ensure their accuracy over time.

Infrared Sensors

In contrast, infrared (IR) sensors measure natural gas by detecting the specific wavelengths of light absorbed by gas molecules. Natural gas, primarily methane, absorbs infrared light at specific wavelengths. IR sensors use a light source to emit a beam of infrared light through the air in the sensor chamber. If natural gas is present, it absorbs some of the infrared light, and the sensor measures the reduction in light intensity to determine the gas concentration. These sensors are less susceptible to poisoning or saturation and do not require oxygen to function, making them suitable for a wide range of applications, including areas where gas is likely to build up in an oxygen-depleted environment. However, IR sensors are typically more expensive than catalytic sensors and may not detect all types of gas, which could be a limitation in environments with a variety of combustible gases.

Both types of sensors play crucial roles in monitoring and maintaining safety in hazardous environments. Selecting the right type of natural gas detector depends on various factors, including the specific gas to be detected, the potential concentration levels, environmental conditions, and the required sensitivity and accuracy of detection. At the Intrinsically Safe Store, we offer an extensive range of both catalytic and infrared natural gas detectors, ensuring that you can find the right solution tailored for your specific safety needs in hazardous environments.
