When you are in an industrial area and smell rotten eggs, you can be sure this means hydrogen sulfide is in the air. Since this can be a very dangerous situation, time is of the essence to get the area evacuated and the leak stopped before more damage is done. To cope with these situations, industrial facilities rely on hydrogen sulphide transmitters that are installed in various areas where an H2S leak may be most likely to happen. However, as technology has transformed these transmitters over the years, it has become a greater challenge to know how to properly pick the best transmitter for a facility. If you need assistance with this task, here are some tips to keep in mind.

Alarm System Capabilities

When choosing hydrogen sulfide gas detectors for your facility, always make sure they are equipped with several different types of alarm systems. Since most of today’s newer transmitters come with this capability, this should be the easiest part of the selection process. In most cases, the transmitter will have such alarms as sirens, strobes, and flashing lights. Not only will this allow them to be installed in any type of work environment, but also make them capable of alerting workers of danger even if such obstacles as noise or facility layout are present.

Confined Spaces

If your facility contains many confined spaces, it will be imperative you select H2S gas detectors that can accurately and reliably monitor these areas. Since confined spaces often contain many types of machinery as well as complex systems of pipes and valves, these areas are well-known for having H2S gas buildups. Along with installing fixed H2S sensors near these areas, most facilities now also use portable sensors and detectors for employees who will be working in these areas. Smaller than most cellphones, the detectors can clip to clothing and offer hands-free monitoring. In addition, while a technician is inspecting equipment, performing troubleshooting procedures, or repairing pipes or valves, the portable detector can gather and transmit data in real-time, ensuring they will remain safe.

Manual and Self-Calibration

For data to be accurate and reliable on a regular basis, an H2S transmitter must be properly calibrated for the work environment in which it is placed. Since work areas may have such conditions as temperature extremes, high humidity levels, and dust and dirt, these factors will need to be taken into consideration when selecting a transmitter. However, due to the technology used in most of today’s transmitters, they are capable of manual as well as self-calibration. By being programmed by engineers in off-site monitoring centers, transmitters can calibrate based on environmental conditions and gas levels present in the air. However, they can also be manually calibrated by on-site technicians, which can be important when testing becomes necessary.
