What are Gas Sensors & How is the Market Booming?

Gas sensors are devices that monitor the presence or concentration of gasses in the surrounding atmosphere. The various types of types of gas include Carbon Dioxide (CO2), Carbon Monoxide (CO), Nitrogen Oxides (NOX), Methane (CH4), and Volatile Organic Compounds (VOCs) which are all converted to an electrical signal that can be read by the monitoring system of a manufacturer or discloser. There are several sensing technologies used to manufacture gas sensors. The most common are electrochemical, infrared, and semiconductor catalysts. Electrochemical sensors are used most frequently for measuring toxic gasses at low levels, whereas infrared sensors are often used to measure carbon dioxide and hydrocarbon gasses due to their stability and accuracy.

The gas sensor market has been experiencing rapid growth due to regulatory, technological, and environmental drivers. The oil and gas, chemical, mining, and power generation industries are all expanding rapidly resulting in a high degree of gas sensors being required. The industries are often operating in hazardous areas and if a gas leak occurs there could be a considerable amount of danger. As a result of these factors many companies have begun to implement advanced gas detection technologies as preventive measures, and to remain in compliance with safety requirements.

Future Outlook for Gas Sensors

Transition toward Smaller, Low Power Gas Sensor Technology

• Due to developments in the use of micro-electronics and nanoscale materials, compact gas sensors can now operate with significantly less power than conventional chemical-based sensors. The miniaturization of sensors is also making it possible for them to be integrated into portable devices, smartphones and wearable safety equipment, thus allowing for gas detection to be more easily accessible throughout multiple industries.

Increase in Use of Infrared/Optical Sensors for Gas Detection

• Infrared and Optical gas sensors are being increasingly used due to their greater accuracy, longer life-span and lower maintenance requirements than conventional chemical-based sensors. Because of these advantages, infrared and optical sensors are anticipated to replace chemical-based sensors in applications requiring continuous (i.e., long-term) monitoring.

Growth of Portable/Wearable Devices Used for Gas Detection

• There is an increasing trend toward portable gas detection devices which will be able to be carried by personnel working in potentially hazardous environments. Wearable devices have become prevalent within industries such as oil & gas, mining and firefighting where they provide real-time alerts of exposure to hazardous gases and increase safety of workers.

Gas Sensors Market Dynamics

Driver

The Need for Air Quality Monitoring and Safety in Industrial Settings

The rapid growth of demand for gas detectors is due in part to the heightened anxiety surrounding air pollution along with the increased requirements for safety in industrial workplaces. As governmental bodies and the regulates impose more stringent standards for air quality, gas detectors are being used in urban centres and at industrial sites on a large scale. With The world health organisation (WHO) estimates that 7 million people die prematurely from air pollution each year, there is a clear example of why continuous monitoring of toxic gas emissions is needed.

In industries such as oil & gas refining, chemical manufacturing and mining, gas detectors will continue to play (and already do play) a critical role in preventing the release of hazardous and combustible gases in the workplace and thus protecting workers. Also contributing to the demand for gas detectors and increasing the number of gas detectors needed is the growing trend toward building smarter and more energy efficient commercial buildings with reusable energy systems, (HVAC) heating, ventilation, air conditioning, and other mechanical systems that rely on the use of gas detectors to monitor the indoor air quality.

Restraint

Calibration Requirements and Sensor Performance Limitations

The gas sensor industry is subject to restrictions, such as the requirement for continuous calibration and maintenance of the sensors for accurate measurements. Over time, the response of some gas sensors will become out of calibration because of external factors (temperature, humidity, other gases present in area), which will result in erroneous readings or false positives unless there is a process in place to maintain the sensors correctly. In an industrial environment, it is required to calibrate the gas sensor routinely; therefore, they also incur an expense related to operations and the cost to employ a skilled operator to conduct calibrations.

Furthermore, cross-sensitivity to other gases may impact gas sensor performance; therefore, achieving an accurate measurement of gas within an industrial environment will be difficult for operators. Restrictions associated with gas sensor calibration and performance will inhibit the use of gas sensors, which may have a greater impact on the usage of gas sensors in smaller and medium enterprises, as they typically have lower levels of technical expertise than larger businesses.

Opportunity

Expansion of Smart Infrastructure and Connected Sensor Networks

As smart cities, connected infrastructure, and Industrial Internet of Things technologies continue to grow, gas sensors will have an exciting growth opportunity. Gas sensors are being increasingly integrated into wireless networks and cloud-based platforms to enable real-time monitoring and analytics. Cities are deploying dense air quality monitoring systems to help them make improved environmental policy decisions; for instance, thousands of air monitoring stations operated by the U.S. Environmental Protection Agency utilize gas sensing technology.

The expansion of connected industrial systems has now enabled companies to use sensor data for predictive maintenance & optimization of operations. There is a growing demand for portable, inexpensive and, connected gas sensors which will lead to new innovation and significant scale opportunities for both developed and emerging market segments.
