Non-dispersive infrared sensors, or NDIR, were introduced in the 1960s and have been widely used for gas-leak detection since that time (Fig. 1). This technology works by using infrared light to ...

Maintenance 4.0 for gas detection system. The new smart sensors for gas detection enable industrial mobility and wireless connectivity. For example, Bluetooth wireless connectivity is a new option for ...

Gas detector sensors have a service life and are generally not fail-safe. For instance, a lower explosive limit (LEL) sensor may show a lower reading of explosive gases as it ages. Without observing a ...

A team of researchers at IMDEA Nanociencia institute and Università Cattolica del Sacro Cuore has unveiled a new class of gas ...

In residential properties and commercial industries that rely heavily on propane, natural gas and other combustible gases, ...

In an advance in microsensor technology, researchers have unveiled an ultra-sensitive gas detection method using surface acoustic wave (SAW) sensors enhanced by the physics of exceptional points ...

Today, there are sensor technologies designed to detect almost any gas to which we might be exposed. Some of these technologies include, but are not limited to, infrared and photo-ionization detection ...

A new study confirms the success of a natural-gas leak-detection tool pioneered by Los Alamos National Laboratory scientists that uses sensors and machine learning to locate leak points at oil and ...

Wearable sensors that detect gas leaks Date: April 16, 2021 Source: Pohang University of Science & Technology (POSTECH) Summary: A research team has developed wearable gas sensors that display an ...

Here, Dr. Chris Weber addresses the value of understanding the science of gas detection and the limitations of our equipment, and offers tips for using your equipment most effectively. FDIC ...

Here is a gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications. The circuit operates off a 9V PP3 battery. Zener diode ZD1 is used to ...
