When using a combustible gas detector, you may encounter a variety of problems. These problems may involve the performance, operation, maintenance, and environmental factors of the instrument. The following is a detailed introduction by yi yun Tian xiaobian to possible problems:

1. instrument performance issues

1. Explosion-proof facilities are damaged:

Combustible gas detectors are usually used in flammable and explosive places. If explosion-proof seals are damaged or loose, explosion-proof pipes are broken and other explosion-proof facilities are not repaired or updated in time, when oil and gas leak, it may directly cause a fire.

2. The sensor is aged or damaged:

The sensor is the core component of the combustible gas detector. It may be aged or damaged after long-term use, resulting in reduced detection sensitivity or failure.

3. The instrument shows no or abnormal display:

The instrument cannot display normally due to abnormal power supply voltage, circuit board failure, water inflow into the meter, etc.

4. Alarm value deviation:

The alarm value of the instrument may deviate due to inaccurate calibration, aging of the sensor, etc., resulting in false positives or omissions.

2. operational issues

1, alarm recognition error:

Many people believe that as long as there is an oil or gas leak near the detector, the detector should send out an alarm signal.However, in fact, the detection object of the detector is the combustible gas in the air, and only when the concentration of the combustible gas reaches the set value, an alarm signal will be issued.

2. Improper test method:

When testing the reliability of the combustible gas detector, if the liquefied gas of the lighter is directly used in contact with the sensor, it may cause damage to the gas sensor, reduced sensitivity or failure.

3. Improper operation causes damage:
