가스 검출기 할 수 없음 사용 외부 농도 탐지 범위.
For example, the four gases routinely measured by the four-in-one gas detector are combustible gas, hydrogen sulfide, carbon monoxide, and oxygen. The detection range is as follows:
1. 가연성 가스 (메탄): 사이 10 percent LEL - 25 percent LEL, that is, 0.5 percent methane - 1.25 percent methane gas detector will alarm.
2. 수소 황화물 가스: 가스 검출기 윌 알람 언제 그것 초과 10ppm.
3. 탄소 일산화 가스: 가스 검출기 윌 알람 언제 그것 초과 24ppm.
4. 산소: 언제 그것 is lower than 18.0 percent , the gas detector will alarm.
If the conventional measurement of the four-in-one gas detector exceeds the calibrated concentration detection range, it will cause serious consequences such as damage to the gas detection probe (sensor), failure, or burning.
Another example is a 가연성 가스 검출기 whose detection range is 0-100 percent LEL. If it is used to detect an environment exceeding 100 percent LEL, then if it is used in an environment exceeding 100 percent LEL, the sensor may be burned. For toxic gas detectors, working at a higher concentration for a long time will also cause damage to the sensor. 그러므로, if the gas detector sends an over-limit signal when it is in use, immediately turn off the power switch to ensure the safety of the instrument.
To sum up, we can see that only when the gas detector is used within the calibrated concentration detection range can the the authenticity and reliability of the measurement results of the detection alarm be guaranteed. Exceeding the calibrated concentration detection range will cause serious results such as damage to the gas detection probe (sensor), failure, or burning. In short, gas detectors can effective suppress pre-disasters, so that accidents that may cause disasters are controlled in advance, while protected industrial safety and the safety of workers. Gas detectors need to be combined with specific use environments and required functions. Choose.
