Collecting information and surveying your workplace environment is a vital part of health and safety when working in a hazardous zone. One of the first issues you need to resolve is the reliability of the power supply. Many gas detection systems may rely on one source of power, so you will need a fully certified and reliable power supply that can deliver sufficient amounts of uninterrupted power to devices for long periods.
Gas detection systems come with different specifications. Infrared gas detectors provide great performance and last for a long time with as little signal drift as you would expect which helps to reduce maintenance and recalibration bills. They also should be able to detect specific gases and compensate for temperature and ambient pressure. You will need your infrared gas detectors to be able to operate in the LEL and high concentration range with a linear response across the sensing spectrum.
Infrared detectors have a multitude of uses ranging from petrochemical processing, offshore platforms, tunnelling, gas storage, mining to telecoms and the brewing industry. This gives them a great versatility within Group 1 and Group 2 hazardous areas when detecting carbon dioxide and methane.
Infrared devices usually have a choice of analogue output signals which can be combined with trip amplifiers and sensor controllers to monitor several sensors at once. More sophisticated I/O systems can be integrated for larger operations making them perfect for the mining and tunnelling industries.
You should also be intimately aware of the specifications of your device. The average response time of an infrared device is 20 seconds but they can also have a warm up time of up to 20 seconds as well. All gas monitoring equipment should be accredited and certified from the likes of ATEX for Europe and IECEx internationally.
