Как често прави сензора на а газ детектор трябва да бъде заменен ?

Проблемът на как често сензорът на a газ детектор трябва да бъде заменен често се случва в нашата околност % 2c и като дълго като ние използваме a газ детектор % 2c ние ще лице такова a проблем. Така че как често правя ние замени сензора ?

In fact, there is no recommended maintenance plan for sensor replacement of portable gas detectors. You should not consider replementing sensors as repplacementing your car's gasoline, it is more like filling up the fuel tank. When the sensor does not have sufficient sensitivity to achieve successful calibration, it can be considered that the fuel tank is insufficient and should be replaced. As long as there is oil in the tank, сензор може функция нормално.

A gas detector has a standard method to confirm the status of the sensor and determine how much oil is still in the tank. It is called retained value. The retained value is a measurement of the sensitivity of the sensor, obtained during the calibration of the detector. After the calibration of the detector, the retained values of each sensor will be displayed and stored in the calibration record of the instrument. When the retention value of the sensor is less than or equal to 50 percent of the standard gas concentration, the sensor will fail calibration and must be replaced. When the retained value is between 50 percent and 70 percent of the standard gas concentration, it indicates that the sensitivity of the sensor is in an edge state. At this point, it is possible to consider replacing the sensor to avoid the situation where the fuel tank is completely empty.

So the bottom line should be like this. As long as your sensors have sufficient sensitivity or retention values to successfully calibrate, they can be usedly. It is not necessary to replace the sensor before it fails calibration and cannot be used. Keep an eye on the retention value, so you won't encounter a state where the fuel tank is напълно empty.

Here, I would like to remind all friends that gas detectors, as an important alarm device for detecting gas leakage концентрация, are of self-evident важност. From the задължително инсталация of national laws to the strong requirements of chemical, pharmaceutical and other enterprises, this indicates that we have increasingly attached importance to safety production. Безопасност е а предпоставка за стабилното развитие на обществото и страната%2в и ние трябва да култивираме концепцията на безопасност производство.
