What is the principle of mixed gas detector?
The fixed mixed gas detector is mainly divided into two parts: a fixed probe and an alarm control host, which form a mixed gas detector system;
The probe detects the gas leakage concentration value in the place, and the host is in the monitoring room so that the safety protection personnel can see the value at any time, and take the work of safety protection treatment in time.
The use standard of mixed gas detector
The use of mixed gas detectors is very simple. Isn't it said that there are two types?
The use of the portable mixed gas detector is very simple. Just turn it on, and then preheat for 100s, and then hold it directly in the field to test. If it is a pump type, it can be used in underground, mine, pipeline construction and other places;
Just put the pumped pipe in it, the pump will automatically absorb the gas in the testing place, and then conduct the test;
If the gas to be measured exceeds the standard, it will alarm and warn, and then remind the construction workers to take safety protection measures.
The fixed mixed gas detector is simpler to use, as long as the installation and power-on test are normal;
It will continuously detect the gas to be measured in the site 24 hours a day, the efficiency is very fast, the detection is also very accurate, and no manual operation is required.
The working principle of mixed gas detector
The working principle of the mixed gas detector is that the gas sensor performs a chemical reaction with the measured gas in the air, and the degree of the reaction is converted into a specific value and displayed;
If the value exceeds the lower limit of the alarm, that is, after the unit value of 25% and 50%, the alarm will prompt the relevant security personnel to take protective measures;
For example, turn on the exhaust fan, cut off the source of gas leakage, start the spray system and other equipment;
Dilute the gas that exceeds the standard to reduce it to a safe range or eliminate it completely.
