Carbon monoxide detector can continuously detect the concentration of toxic gases, oxygen, flammable and explosive gases, and observe the current gas concentration value at any time. It is widely used in petroleum, chemical industry, coal mine, metallurgy, papermaking, fire protection, municipal administration, telecommunications, food, Textile and other industries. Moreover, in addition to traditional applications, carbon monoxide gas detectors have also begun to be used in newer requirements, such as smart homes and fire safety in intensive public places. However, many friends do not know much about the classification of carbon monoxide detectors, so they have no way to start when choosing. So what are the categories of carbon monoxide detectors ? The following is an introduction by Yiyuntian:

There are mainly the following types of carbon monoxide detectors:

1. Classified by sensor type:

There are two types of sensors for commonly used carbon monoxide detectors: Electrochemical sensors and semiconductor sensors. The electrochemical sensor has high precision and good stability, so the price is relatively high. The power consumption of the electrochemical sensor is low, and the device can be powered by a battery. Semiconductor sensors have high power consumption and are usually not powered by batteries.

2. Classification by function:

Carbon monoxide detectors can be divided into carbon monoxide detectors with and without control output according to whether they have control output. The carbon monoxide device with control output outputs the switch signal while outputting the sound and light signal, usually a pair of normally open contacts or a pair of normally closed contacts, which can be used to drive the exhaust fan or forcibly open the window. Without control output is only the output acousto-optic signal, no other signal output.

3. Classification according to morphology:

There are three types of fixed carbon monoxide detectors, portable carbon monoxide detectors, and online carbon monoxide detectors. A suitable form of carbon monoxide detector can be selected according to specific applications, so as to facilitate and better carry out gas detection work.

3. Classified by application:

can be divided into industrial and household carbon monoxide detectors. Industrial carbon monoxide detector is expensive, requires very high precision, temperature and zero drift are very small, some special occasions often need to use the shell. Industrial carbon monoxide detectors must use electrochemical sensors. The household carbon monoxide generator is mainly used in ordinary families, small entertainment places and small factories, and small chemical laboratories.

In summary, this is the classification of carbon monoxide detectors.By understanding the occasions where carbon monoxide is produced, we know the place where the carbon monoxide detector is used, so that in the place where the carbon monoxide detector is produced or used, the appropriate carbon monoxide detector is selected for the detection of carbon monoxide.
