When combustible gases are part of the mix, sophisticated systems should be in place to detect dangerous levels of these gases. If this is not the case, the result can be a massive fire or explosion. To keep this from happening, companies rely on catalytic gas detectors. But to make sure the detectors used are the best for a particular work environment, it is important to understand how these detectors function.
When using catalytic gas detection devices, it is important to know the various calibration methods associated with them. For example, catalytic bead sensors usually require frequent monitoring and manual calibration by technicians and engineers who are on the job site. However, when using infrared catalytic sensors, the sensors themselves are programmed to self-calibrate depending upon the work environment conditions. In addition, infrared catalytic detection equipment can also be calibrated by off-site engineers in monitoring centers, which can be useful if an emergency situation arises.
Since more and more companies today rely on mobile devices for numerous functions, catalytic gas sensors are equipped with technology allowing them to use wireless networks to link to various mobile devices. Thus, if a technician is using a tablet to troubleshoot equipment and check various readings throughout a plant, the sensors can be linked to the tablet. Once this happens, the sensors can then transmit real-time data regarding gas levels and equipment performance to a technician or engineer, no matter where they happen to be in a facility.
High Gas Concentrations
In many work environments, high gas concentrations may occur on a frequent basis. For example, offshore drilling platforms or manufacturing plants that contain many confined spaces may be subject to high gas concentration levels. In these cases, this is often due to the confined spaces having various types of equipment located within them, and also having numerous pipes and valves that could potentially leak. Because of this and the need to quickly detect even very small concentrations of gas in these areas, it is usually recommended infrared sensors be used, due to their ability to scan areas using open path technology. However, in larger areas where the threat of a high gas concentration is relatively low, bead sensors often work very well.
While most types of catalytic detection equipment can perform well under extremely adverse environmental conditions, there are some factors that should be taken into consideration. As an example, if the work environment will be subjected to frequent temperature extremes or high humidity levels, infrared sensors are a better choice. Yet if dust and dirt, shocks and vibrations from equipment, or other related factors will be part of the work environment, either infrared sensors or bead sensors will be very accurate and reliable.
