Maintenance and environmental requirements for the detection of combustible gases
Although combustible gas detectors are generally suitable for use in a variety of harsh environments, this does not mean that there are no requirements for the working environment. What are the requirements for the working environment of combustible gas detectors? What maintenance is required?
1, due to the combustible gas detector working environment is generally more harsh, polluting gases and dust may enter the internal instrument. Therefore, it is necessary to clean and maintain the combustible gas detector regularly to improve the accuracy and sensitivity of the instrument.
2, in order to ensure that the gas detector is not subject to electromagnetic interference, it is best to test the grounding of the instrument, to eliminate the instrument is not grounded or grounding substandard conditions.
3, to ensure the reliability of the instrument, to prevent the instrument component failure caused by aging. The system should be replaced in time if it is out of service.
4, different applications, should be used in different gas detector. Use of gas, natural gas, liquefied petroleum gas places should be selected semiconductor-type combustible gas detector, while the dissemination of combustible gases, combustible vapours of industrial premises is best to use catalytic combustible gas detector.
Portable gas detector daily use precautions
1: Portable gas detector under normal working conditions detection, sensor life of more than two years.
2: Prevent the portable gas detector from falling from a high place or subject to severe vibration.
3: If the machine appears for a long time no response phenomenon, please turn off the portable gas detector power restart.
4:You need to use the portable gas detector in a place without corrosive gases, fumes, dust and rain.
5: In order to ensure the accuracy of measurement, portable gas detector should be calibrated regularly, the verification cycle shall not exceed one year.
6: Do not make the portable gas detector often contact with high concentration of gas above the detection range, and strictly prohibit collision and disassembly of the sensor, otherwise it will lose the working life of the sensor.
