Long Life Span
GD2G Infrared Fixed Gas Detectors
GD2G Infrared Fixed Gas Detectors detect flammable-explosive gases with high sensitivity. It does not require frequent calibration and has a long lifetime. Infrared sensor technology does not measure based on a chemical reaction like catalytic or electrochemical sensors. They work on the principle of measuring the absorption amount of infrared rays in different gases. They are not affected by temperature, pressure and other gases which are harmful effects in the environment. In this way, it provides high performance and does not require continuous calibration, does not require maintenance and provides a longer-lasting solution.
GD2G Infrared Fixed Gas Detectors have an advanced micro-controller chip in the smart circuit board. Its embedded software algorithm guarantees perfect detection under all conditions. It also enables software optimizations according to the needs of your facility.
GD2G Infrared Fixed Gas Detectors can be used as an independent device with digital relay outputs (NOC), and can be easily integrated into your control and automation system thanks to its industrial standard 4-20mA analog outputs. It reacts immediately if target gas is detected at the lower and upper alarm limits you have specified. Dangerous conditions for the safety of your staff and facility are avoided before they grow.
