Gas Detection Sensors

In many different types of industrial settings, various gas detection sensors are used to monitor and detect the presence of hazardous gases. The reliability with which harmful airborne substances can be detected depends, to a large extent, on the sensors that are used. It is important for the gas detector and sensor to be adapted to each other. Hazards must be identified quickly and dependably, and false alarms leading to production downtime and the like must be avoided.

The selection of a particular type of gas detection sensor depends on factors such as the type of gas to be detected, the concentration levels, temperature, humidity, and the specific requirements of the industrial environment. 

Some of the more common types of gas detection sensors used in industrial settings are:

Electrochemical Sensors: These sensors operate based on the chemical reactions that occur when a target gas encounters an electrode. They are commonly used for detecting gases such as carbon monoxide (CO), hydrogen sulfide (H₂S), and oxygen (O₂).

Infrared Sensors: Infrared gas sensors detect gases by measuring the absorption of infrared radiation at a specific wavelength. They are effective in detecting hydrocarbons and certain other gases. In industrial settings, they are often used for detecting combustible gases and carbon dioxide.

Catalytic Bead Sensors: These sensors utilize a heated catalytic bead that oxidizes combustible gases, leading to a change in temperature. This change is then measured to detect flammable gases such as methane and propane.

Photoionization Detectors (PID): PID sensors use ultraviolet light to ionize gas molecules, and the resulting electrical current is measured to detect the concentration of volatile organic compounds (VOCs) and other gases.

Properly functioning sensors can help to maintain the safety and protection of your personnel, equipment, and property. Draeger provides comprehensive sensor solutions in our portfolio of small wearable single & multi-gas monitors and stationary gas detection systems that can monitor your entire facility. 

Portable gas detectors may have a single gas sensor or may include a combination of different sensor types to provide comprehensive coverage. The selection of sensor(s) depends on the specific gases to be monitored, the intended application, and safety requirements.

Fixed gas monitors are often configured with a combination of sensors to provide comprehensive coverage for multiple gas hazards. These systems are designed for continuous monitoring and may include features such as alarms and communication capabilities to help ensure a rapid response to gas leaks or hazardous conditions.
