What are the common faults of gas detectors?
Long term use, improper storage, and use of gas detectors may cause malfunctions and reduce their lifespan. So, what are the common gas detector malfunctions?
1. Unable to display correctly
If a gas detector is used for a long time or not calibrated for a long time, the problem of reading errors may occur. We all know that gas detectors mainly detect through internal sensors, which have a certain lifespan. After a certain number of uses, the sensitivity of the sensor decreases, which affects the detection results. In addition, if calibration is not carried out for a long time, it will also affect the detection results.
2. The gas detector cannot inhale air
This type of problem mainly occurs in pump suction gas detectors. By using a small suction pump inside the detector to suck in gas for detection, if the suction pump is damaged or malfunctions, it will cause the gas detector to be unable to suck in. This problem is easy to solve by replacing the suction pump with a new one.
3. Gas detector malfunction
This type of malfunction is prone to occur in special working environments, such as when there is a lot of dust and oil pollution in the detection environment, which can contaminate the gas detector and cause it to malfunction. In such environments, it is necessary to clean the gas detector.
Maintenance methods for gas detectors
1. Regular inspections should be carried out, and calibration and impact testing should not be forgotten.
2. Keep away from moisture, rainwater, and corrosive liquids to ensure the surface of the instrument is clean and dry.
3. Do not hit or shake the machine strongly, and do not drop or use it roughly.
4. Regularly replace filter paper.
Precautions for maintenance of gas detector
1. Check the gas flow rate, the value should not be too large or too small.
2. Check for any air leaks in the pneumatic system.
3. Clean the sampling probe and unclog the sampling hole pipeline.
4. Check if the condenser is working properly, usually adjust the temperature within the range of 3 degrees Celsius.
5. Check the measuring room for dirt and clean it promptly.
