I believe everyone knows that the main function of the hydrogen alarm is to detect the concentration of hydrogen gas in the air. When the concentration in the air reaches a certain concentration, the hydrogen alarm will automatically sound and light alarm to remind the staff Take corresponding measures in time to avoid major accidents. However, when we use the hydrogen alarm, sometimes the display value error is large or there is no indication. Do you know what to do if hydrogen alarm shows a large error or no value? The following is a brief introduction by yi yun Tian:

Large Error in Fault 1. Display

Part of the reason for this failure is that the hydrogen alarm probe has not been effectively calibrated for a long time, as a result, the sensitivity of the sensor is greatly reduced, resulting in inaccurate measurement results of hydrogen gas concentration. In addition, according to the analysis of drilling site operation, the hydrogen alarm probes are mainly distributed at the wellhead, drill floor and other positions, which makes the surface and gas flameproof membrane easily polluted by mud and drilling fluid, and the flameproof membrane is also easily soaked by rain in rainy weather. These are hydrogen alarm indications that can cause errors.

Handling:

1. Regularly check the usage of the hydrogen alarm probe, regularly clean the flameproof membrane, and regularly calibrate the sensor.

2. Install a rainproof device for the probe installed in the open air.
