The carbon monoxide alarm is an important security device for detecting the concentration of carbon monoxide gas leaks. Many people think that the carbon monoxide alarms are the same. In fact, there are many types of carbon monoxide alarms, each of which is different. Now let me explain the types and differences of carbon monoxide alarms.
First: According to the type of sensor: There are two commonly used carbon monoxide sensors: electrochemical sensors and semiconductor sensors. Electrochemical sensors have high precision and good stability, so the price is relatively high. The electrochemical sensor has low power consumption, and the resulting alarm can be powered by a battery. Semiconductor sensors consume a lot of power and are usually not powered by batteries.
Second: According to the function points: according to whether the control output points can be divided into two types: the control output and the carbon monoxide alarm without control output. The carbon monoxide alarm with control output is also outputting the switch signal while outputting the sound and light alarm signal. It is 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 the control output, only the audible and visual alarm signal is output, and no other signal is output.
Third: According to the application, it can be divided into two types: industrial and household carbon monoxide alarms. The Chuangan brand industrial carbon monoxide alarm is expensive, requires very high precision, and has a small temperature and zero drift. In some special occasions, an explosion-proof enclosure is often required. Chuang'an brand industrial carbon monoxide alarm must use imported electrochemical sensors. The Chuangan brand household carbon monoxide alarm is mainly used in ordinary households, small entertainment places and small factories, as well as small chemical laboratories. The appearance is relatively small and the price is relatively low.
The above is the introduction of the carbon monoxide gas alarm, so the procurement must be based on these in order to purchase the appropriate safety equipment.
