Smart fire alarm

Sensors applied in fire prevention and fire fighting are mainly pressure sensor, flow sensor, temperature sensor, smoke sensor, infrared sensor, gas sensors, etc. Take fire alarm as an example, The automatic fire alarm system is one of the important device of daily life and industrial safety monitoring system. It is an important way to ensure safe operation and reduce casualties and property losses in case of fire. Traditional smoke and temperature sensing alarms have wide use due to its low cost and simple manufacture process. But most of them are used to detect gas concentration and can’t detect fire flame have defects like responding in long time and not good at anti-inference, can’t defect fire without smoke, etc. As sensing technology advancing, there are new detecting products to solve these problems, and improve fire prevention efficiency.

1.Flame detector

Flame detector, also known as photosensitive fire detector, used to respond to the light characteristics of fire, including the light intensity, the flicker frequency, visible and invisible radiation of flame during burning. This infrared flame detector based on the principle of pyroelectricity can be applied to short and long distance, multi-band flame detection. It has the advantages of fast response, long detection distance, and large protection area, especially for flames formed by hydrocarbon combustion. Therefore, it is more suitable for inflammable and explosive industrial and civil places such as chemical industry, road tunnels, ammunition warehouses, paint factories, petrochemical enterprises, pharmaceutical enterprises, power plants, logistics warehouses, etc.

2.Fuel gas alarm

The continuous occurrence of gas explosion safety accidents has repeatedly alarmed us for the fuel gas safety and reminded us that it is very important to take effective measures to prevent gas safety hazards and strengthen the monitoring of gas leakage and combustion products. Based on our own R&D team, Winsen has developed a variety of sensors that can detect natural gas in the air for the application of .

3.Smoke alarm

The smoke alarm gas sensor can detect the smoke generated when a fire occurs, and is an effective and practical fire detection and alarm tool. At present, smoke alarm gas sensors are standard use in fire safety detection of large supermarkets, hotels, apartments, warehouses and factories. With the rapid development of modern science and technology, the smoke alarm sensors have been greatly improved on performance and reliability. Winsen has developed a variety of sensors that can detect smoke in the air.
