What is the principle of the mixed gas detector?
The fixed mixed gas detector is mainly divided into two parts: fixed probe and alarm control host, which form a mixed gas detector system;
The probe detects the value of the gas leakage concentration 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 timely safety protection measures.
Standards for Mixed Gas Detectors
The standards for using mixed gas detectors are very simple. Didn’t the above say that there are two types?
The use of the portable mixed gas detector is very simple. Just turn it on, and then warm it up for 100s, and then hold it directly to detect it in the place. If it is a pump suction type, it will be used in underground mines, mines, pipeline construction and other places;
Just put the pumping tube in it, the pumping will automatically suck up the gas in the detection place, and then carry out the detection;
If the gas to be measured exceeds the standard, an alarm will be issued and an early warning will be issued, and then construction personnel will be reminded to take safety protection measures.
The fixed mixed gas detector is easier to use, as long as the installation and power-on test are normal;
It will continuously detect the gas to be measured in the place 24 hours a day, the efficiency is very fast, and the detection is very accurate, without any manual operation.
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 reaction is converted into specific values to display;
If the value exceeds the lower limit of the alarm, that is, after the unit value of 25% or 50%, an alarm will be issued to remind relevant security personnel to take protective measures;
For example, turn on the exhaust fan, cut off the source of gas leakage, start the sprinkler system and other equipment;
Dilute the excess gas to reduce it to a safe range or eliminate it completely.
