What are the sampling methods of carbon monoxide detectors?
Carbon monoxide is a common gas that we use. When we need to measure the concentration of carbon monoxide in the environment, we need to use a carbon monoxide detector. The main function of the carbon monoxide detector is to detect the concentration of carbon monoxide in the working environment. When the concentration of carbon monoxide in the working environment exceeds a safe concentration preset by the carbon monoxide detector, the carbon monoxide detector will send out an alarm signal to remind on-site workers to pay attention to protection and take necessary emergency measures. So what are the sampling methods of carbon monoxide detectors?
Sampling method of carbon monoxide detector:
1. As can be seen from its name, the pump-type carbon monoxide detector uses a small air pump. Its working method is that the power supply of the instrument drives the air pump to pump and sample the gas in the detection area, and then inhales the carbon monoxide into the instrument. Perform testing. Its characteristic in use is its fast detection speed. If it needs to be used in hazardous areas, you can choose to install an instrument with a handle, which can achieve long-distance measurement. To measure the safety of workers, the usage method is similar to other diffusion gas detectors.
2. Diffusion carbon monoxide detector means that the gas in the measured area will flow slowly and freely into the detector with the air for measurement. However, it will be affected by the environment, such as ambient temperature, wind speed and other factors. The advantage of using a diffusion carbon monoxide detector is that it is relatively low cost.
The above sampling methods of carbon monoxide detectors are shared with you here. Generally speaking, the sampling methods of carbon monoxide detectors are divided into pump suction type and diffusion type. Their working principles are basically the same. They both detect gas through sensors. The signal is amplified through the circuit and the measurement results are displayed on the screen.
