When undetected levels of dangerous gases are not quickly found, the result is a fire or explosion. Since industrial facilities, medical and research laboratories, manufacturing plants, and other similar settings have the potential for undetected gas leaks, sophisticated monitoring systems must be in place as a safeguard against these events. Some of the most popular detection systems used today are LEL monitors, also known as Lower Explosive Limit detectors. Containing precise electronics, these monitors scan areas for gas levels falling within a certain range, transmitting real-time data to engineers. To gain a better understanding of how an LEL gas detector works, here are some details about its features.
A major component of modern gas detection technology, electrochemical sensing is a big reason why LEL gas monitors are considered to be very accurate and reliable in many different types of work environments. Rather than using strictly one pathway to monitor gas levels, these detectors use multiple pathways, enabling them to detect gas levels much faster than many other types of detectors. As a result, by using open path as well as sample draw detection, extremely small amounts of gas can be detected, allowing for the source to be located and repairs made before a situation turns critical.
Since LEL meters are used in work environments where noise levels may be high or that contain numerous confined spaces and isolated areas, they are equipped with multi-alarm capability. By having this feature, they can ensure workers in any setting can be alerted to danger very quickly. In having sirens that can be used to alert workers spread out over long distances or who are unable to see warning lights, as well as strobes and flashing lights that can be used in noisy work environments, LEL detection systems can be relied upon to work well under the most difficult of conditions.
When gas levels begin to rise, the surrounding environment can experience many atmospheric changes. When this happens, it can sometimes be difficult to ensure the data being transmitted from various sensors is accurate and reliable. Due to this possibility, LEL sensors are equipped with state-of-the-art calibration features, allowing them to self-calibrate based on changing conditions within the work environment. Along with this, engineers in monitoring centers can program the sensors to be properly calibrated, and if necessary on-site engineers and technicians can use controlled amounts of gases to test the sensor’s accuracy. In having multiple calibration options, the sensor’s accuracy and reliability will rarely waver.
Expandable Wireless Networks
With most facilities now relying on wireless networks, LEL detection systems are also equipped with wireless technology. This allows for a variety of options, such as expanding the number of sensors positioned within a facility. In many cases, as many as 12 additional sensors can be added to the network. Along with this, the sensor network can be linked to mobile devices, allowing engineers and technicians to have 24/7 access to data no matter where they are located.
