About Gas Sensors for Air Quality and Applications Leak Detection

A gas sensor is a device used to determine the presence and amount of a specific gas or gases. The gas sensor system is typically manufactured to detect a specific family of gasses or specific gas and convert that measurement into a resistive electrical signal that can be interpreted by the system. Several factors influence the quality of a gas sensor, including accuracy (how accurate is the measurement), sensitivity (detection of very low levels of gas), selectivity (how well it performs in the presence of other gases), and stability (how reliably it performs year after year).

Renesas' digital and analog gas sensors provide industry-leading specifications, addressing industrial leak detection and Air Quality including TVOC, O3 & NOx as well gasses found in refrigeration systems. Options are available for measuring the presence of hydrogen gas, methane gas, propane gas, liquefied petroleum gas (LPG.

MOx Sensor Technology Offers Superior Performance

MOx sensors, sometimes called chemiresistive sensors, are well known for their ability to offer affordable, reliable performance in harsh applications compared to non-MOx sensors. MOx materials and appropriate deposition methods that have a long history of use in critical applications with well-documented stability and reliability.

Liquefied Petroleum Gas (LPG) and Propane Gas Sensors

Liquefied petroleum and propane gas sensors are used to detect mixtures of hydrocarbon gases. These gases are used for fuel in heating appliances, cooking equipment, and vehicles. Unfortunately, these systems have the potential to leak small quantities of gas into the environment. While there are well-established approaches to quantifying explosive levels, such as pellistors and non-dispersive infrared (NDIR) sensors, detection of trace or ppm levels is a challenge for many sensor technologies. The high sensitivity and fast response time of Renesas propane gas sensors make finding leaks easier.

Methane Gas Sensors

Methane gas sensors monitor the colorless, odorless, hydrocarbon gas. Quick detection of this gas is vital, as this is a contributor to climate pollution and global warming. While there are well-established approaches to quantifying explosive levels, such as pellistors and non-dispersive infrared (NDIR) sensors, detection of trace or ppm levels is a challenge for many sensor technologies. The high sensitivity and fast response time of Renesas methane gas sensors make finding leaks easier.
