The primary job of the combustible gas detector is to determine whether the airborne flammable gas concentration exceeds a certain unsafe level. The combustible gas detector will automatically send out an audible and visual alarm to remind people to take the necessary precautions in time to avoid major accidents when the airborne combustible gas concentration reaches a certain level. This ensures both the safety of production and the safety of workers.
One piece of safety gear that is frequently used in chemical industry businesses is the combustible gas detector. Along with paying attention to routine upkeep and repairs, some issues are always disregarded while in use.
1. The display of combustible gas may be lower than the actual concentration if a portable or fixed combustible gas detector is used in an environment with limited oxygen. In contrast, a flammable gas detector may give a result that is higher than the real concentration in an oxygen-rich atmosphere.
2. The combustible gas sensor needs to be calibrated if the combustible gas report concentration gauge displays "above range." For instance, a flammable gas detector's measurement range is 0-100% LEL; if the actual concentration is higher than 100%, the detector will be out of range. The gas sensor needs to be recalibrated at this stage.
3. The combustible gas detector's normal operation may be hampered by water vapor or other recognized sources of silicone compounds, resulting in readings that are lower than the actual gas concentration. To ensure reliable measurements, recalibrate the instrument before the next usage if it is utilized in a water vapor environment with silicone compounds.
