As we all know, the ammonia detector is currently used to detect the 1 kind of detection instrument for ammonia concentration in the environment. When the concentration of ammonia in the environment reaches or exceeds the preset alarm value, the ammonia detector will send out sound and light and vibration alarm signals. So do you know how the ammonia detector works? The following Yi Yuntian Xiaobian for you to introduce:

the detection principle of ammonia detector generally includes electrochemical or semiconductor principle sensors. The sampling method is divided into pump suction type and diffusion type. The ammonia gas detector mainly consists of sampling, detection, indication and alarm. When the ammonia gas in the environment diffuses or sucks to the sensor, the sensor converts the ammonia gas concentration into a certain size. The electrical signal, and then the concentration value is displayed by the display.

Air and the measured gas diffuse to the induction electrode through the diffusion membrane. The control circuit maintains a voltage between the sensing electrode and the counter electrode sufficient to initiate an electrochemical reaction. The electrochemical reaction generated under the action of the measured gas can form an electric current between the two poles. The intensity of this 1 current is proportional to the concentration of the measured gas and is reversible. The control circuit also creates a bias level between the sense electrode and the reference electrode that does not create a current between the two poles.The rapid response of the sensor enables real-time, continuous detection of the surrounding air.

In summary, it is the working principle of the ammonia gas detector. Ammonia detector compact and economical design can be used in the case of a variety of harmful gases, can be widely used in various types of cold storage room, there is ammonia in the laboratory, ammonia storage warehouse and other applications to ammonia industrial sites, can effectively prevent poisoning, explosion accidents, to protect life and property safety.
