Six misconceptions about gas detectors
Myth 1: Gas detectors can detect any gas
A detector can only detect a specific gas. Composite gas detectors can only detect several gases simultaneously.
Myth 2: Gas detectors can be installed freely
Strictly require the installation position of gas detectors. The installation position is incorrect and cannot be detected properly.
Myth 3: Using high concentration gas testing during acceptance
Some customers use high concentration gases for testing during the acceptance process. This approach is very loose and can easily damage the instrument. The detection range of the combustible gas detector is 0-100% LEL. Testing with gases higher than this concentration range is likely to fumigate the sensor, causing damage or detection failure!
Myth 4: As long as there is combustible or toxic gas around the gas detector, the alarm should sound an alarm
The condition for a gas detection alarm to alarm is that an alarm signal will only be issued when the measured gas concentration reaches or exceeds the preset value of the instrument.
Myth 5: Damage to the explosion-proof facilities of the gas detector itself does not affect its use
During use, if there are signs of damage to explosion-proof facilities such as alarm explosion-proof seals, looseness, and rupture of explosion-proof pipes, it is necessary to repair them in a timely manner.
Myth 6: Gas detectors do not require maintenance and upkeep
A gas detector is a measuring instrument that requires regular calibration to ensure the accuracy of its detection. Long term use of gas detectors can cause drift, and if not calibrated in a timely manner, the error will become increasingly large, posing a safety hazard.
According to regulations, the maximum calibration cycle of gas detectors should not exceed one year, and enterprises with specialized metrology departments suggest that it should not exceed three months. The calibration of gas detectors should be operated by professional personnel.
