Continued development and refinement of advanced low-power LED photometric infrared technology for LEL detection of hydrocarbon gases has made gas detection more reliable and safer than ever before. In recent years, new high-performance low-maintenance portable gas detectors featuring infrared technology that reliably warn of exposure to combustible gases (Lower Explosive Limit – LEL), hydrogen sulfide (H2S), carbon monoxide (CO) and oxygen (O2) deficiency levels have been put to the test. When first introduced, these detectors were able to operate continuously 24 hours a day for 2 months or longer without having to recharge the battery. Advancements in infrared LEL sensor technology have led to the development of 4-gas detectors today that can run for as long as 2 years continuously with no charging. Just turn them on, clip them on, and these simple-to-use and simple-to-maintain detectors provide protection for 24 months with very little to no maintenance at all. What makes these portable gas detectors able to perform this well for this long even under the harshest of conditions?
It’s not the battery type, it’s the sensing technology
Infrared LEL sensor technology for portable gas detection has an extremely low drain on the detector battery. The infrared LEL sensor doesn’t have to continuously heat up to detect gas which allows the battery to last for months instead of hours. There are other benefits besides long run times that contribute to the safety features of portable gas detectors equipped with infrared technology. Infrared LEL sensors need no oxygen to detect gas. They detect gas with an infrared beam of light, so they always can detect gas accurately in oxygen deficient environments. Infrared LEL sensors are durable and dependable. They have no fragile filament or bead to break, burst or get poisoned and do not suffer from reduction in sensor life after repeated exposure to gas. Due to advanced infrared sensor technology and current designs, some detectors are factory calibrated and virtually maintenance free. This makes gas detection easy in remote areas where detectors cannot be easily calibrated on a regular basis. The continuous self-test and fail-to-safe functions of the infrared LEL sensor give assurance that you are always protected. Infrared sensing is an active technology which continuously monitors for sensor failures and immediately communicates them to the wearer. You can focus on the job at hand having confidence that your gas detector is always operable and will alert you when there is gas exposure danger.
Tested technology you can trust
Infrared technology being utilized in gas detection is not something new. It has proven to be a reliable method of gas detection for many years in fixed gas detection applications. Like the advancement of technology in phones that has allowed phones to become portable and smaller with better performance, advancement of infrared technology in gas detection has allowed it to be miniaturized and placed in portable gas detectors. These detectors can now be worn to provide a constant personal warning system with no down time. Since the first portable gas detector using a low-energy infrared beam of light inside the LEL sensor was introduced several years ago, many advancements in safe gas detection have been made. Gas detectors are now easier to operate, more reliable, more reasonably priced and have lower maintenance costs over their lifetime.
