The principle of gas detectors

- Jun 13, 2018 -

The incident particle causes the gas to be ionized between the high-voltage electrode and the collecting electrode, and the generated electron ions drift toward the two poles under the action of the electric field, generating an output pulse on the collecting electrode, and feedback to the measuring system called the specific electrical signal and displayed on the screen. Wrong This is the principle of a gas radiation detector, not the principle of a combustible gas detector. The general principle of a combustible gas detector is to detect the measured gas by electrochemical method. The gas radiation detector is used to detect the number of incident particles of the counter, such as Geiger counters, proportional counters and other things. )
