An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber. ASDs can typically detect smoke before it is ...

Wherever wine is stored and matured, gases will also be present, the most frequent and well-known of which is carbon dioxide. The potential for carbon dioxide levels to rise in the confines of a wine cellar is quite high and the installation of a CO2 gas monitoring system can mitigate this health hazard.

A nondispersive infrared sensor is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element is used to separate out the broadband light into a narrow spectrum suitable for gas sensing. The majority of …

Most of gas boiler rooms run without permanent monitoring and a gas leak could stay unnoticed.Boiler rooms gas detection controllers mainly remove these risks triggering valve actuators. In presence of any flammable gas detection (liquefied petroleum gas or natural gas), a controller will shut down gas supply with a gas solenoid valve installed outside the boiler room.
