gas detectorGas sensors are primarily utilized to detect the types of gases present in the environment. Gas sensors are used to detect the composition and content of gases. Gas detectors are widely used in petrochemical, coal, chemical and other industries, which can effectively protect people's lives and property. So do you know which gas detectors are divided according to the detection method? Let's find out more and hope it will be helpful to you.
Gas detectors can be divided according to the number of gases detected
Single gas detector and all-in-onegas detector
A single gas detector can only detect one gas, and an all-in-one gas detector can detect multiple gases. For those who are not familiar with the LEL and ppm ratios in the picture, you can click on the ppm Vol LEL on the gas detector What does "comb" mean? Find out.
According to the sampling method: DiffusionGas detectorand pump suction gas detectors
Diffusion gas detector: DiffusionGas detectorIt needs to be placed on site, and the gas to be measured slowly flows into the detector for detection.
Pump suction gas detector: pump suction typegas detectorIt is equipped with a gas sampling pump to sample the gas to be measured. Faster detection speed, long-distance measurement, and greater security compared to diffusion types.
According to the detection gas: combustible gas detector, toxic gas detector
gas detectorAccording to the detection method, it is divided into
, according to the installation method: benchtop gas detector andHandheld gas detector
, according to the principle of gas sensor: infrared gas detector, electrochemical gas detector, semiconductor gas detector
Infrared gas detectorAdvantages: Less affected by the environment, high precision, long service life
Disadvantages: There are few types of gases to be detected, and they are greatly affected by humidity
Advantages: large measurement range and high sensitivity
Disadvantages: short service life and greatly affected by humidity
The above is the whole small series of Values for you to share, this article shares with you through the four aspects of sampling method, gas detection method, installation method, gas sensor principle gas detection According to the detection method, which gas detector can be divided into?
